The Most Reliable Cargo Vans

If you're thinking about buying a Mercedes or already own one, it's normal to wonder how long it will actually last. We hear this question all the time. The short answer?  If you keep up with maintenance, most Mercedes-Benz vehicles will run strong for 200,000 to 250,000 miles. Some of models like the E-Class and S-Class can even hit 300,000 or more. Of course, how long your car lasts depends on things like how you drive it, how often it’s serviced, and which model you’ve got. But if you treat it right, a Mercedes can easily go the distance. Mercedes Vehicles Are Built to Last Mercedes puts a lot of engineering into their vehicles. You get solid drivetrains, high-quality components, and well-designed systems. But even a great vehicle can wear out early if it's not cared for. If you stay on top of oil changes, fluid services, and repairs when they first show up, your Mercedes has a real shot at lasting longer than most cars on the road. Some people run into issues because they wait too long between services or skip them altogether. Ignoring things like coolant leaks, check engine lights, or transmission problems might save you money in the short term, but it usually leads to bigger repairs later on. Gas vs Diesel Longevity Most Mercedes owners are driving gas-powered models, but diesel engines are known for lasting even longer with the right upkeep. If you're running a diesel, just know there are extra systems to watch, like the DPF and DEF systems. If those go unchecked, repairs can get pricey. But with regular inspections and the right service schedule, both gas and diesel Mercedes vehicles can stick around for a long time. Service Makes a Difference One of the biggest things that impacts the life of any Mercedes is where you take it for service. Not all shops know how to work on these vehicles properly.

Wondering how often you should change the oil in your Sprinter? If you drive a diesel MB Sprinter van, you already know it’s built to work hard. But like anything that runs long miles, it needs regular care to stay in good shape. One of the biggest maintenance items? Oil changes. For most diesel Mercedes Sprinter diesels, it’s a good idea to change the oil and filter every 10,000 miles or once a year, whichever comes first. If you’re doing a lot of stop-and-go driving, towing heavy loads, or spending time in extreme temperatures, it’s smart to do it a little more often. Those kinds of conditions can wear the oil out faster, so staying on top of it can help avoid bigger problems down the road. At Colorado Fleetworks, we service and repair Sprinter vans in our Denver shop to the tune of dozens every week. We’ve seen what happens when oil changes are done on time, and we’ve seen what happens when they’re not. The Short Answer For most Mercedes Sprinter diesel engines, the recommended oil change interval is about 10,000 miles or once a year , whichever comes first. That’s assuming you’re using the correct synthetic oil and OEM filters. If your Sprinter is part of a fleet, gets heavy daily use, or spends a lot of time idling, you might want to change it closer to every 7,500 miles to stay ahead of wear. Why Oil Changes Matter More Than You Think Sprinter diesel engines are tough, but they run hot and work hard. Over time, oil breaks down and collects gunk from combustion. If you push your oil past its limit, it can lead to things like sludge buildup, reduced fuel efficiency, or even early engine wear. Clean oil keeps everything moving the way it should and helps your engine last a lot longer. Don’t Forget the Filter We always recommend swapping out the oil filter with every change. Dirty filters can’t do their job, and keeping them fresh ensures that contaminants don’t cycle back through your engine. It’s a simple step that can prevent expensive problems later on. Signs You Might Be Overdue If you’ve gone too long between changes, you might notice sluggish performance, engine noise, or reduced fuel economy. Some Sprinters will even throw a warning light when it’s time. But you don’t need to wait for a signal. Regular oil service is cheap insurance compared to what engine repairs cost. Book Your Oil Change with Sprinter Experts We’ve been working on Sprinters in the Denver area since 2015. Whether it’s a routine oil change or a full inspection, we can help you get the most life out of your van. If it’s been a while or you’re not sure when your last service was, stop by and we’ll take care of it. You keep the van moving. We’ll help keep it running right.

If you've got a cargo van, camper van, or fleet vehicle that needs body work, you already know it’s not exactly fitting into your average garage. These things are tall. And wide. And long. And most body shops just aren’t set up to handle that. That’s where having a shop with large bays and tall paint booths makes all the difference. Size Matters (A Lot) Standard auto body shops are built for regular passenger vehicles. But when you roll in with a high-roof Sprinter or an extended Ford Transit, suddenly the game changes. Without extra-tall ceilings and oversized paint booths, a shop simply can’t get your van inside, let alone repaired and painted properly. You can’t exactly buff out a dent on a roof you can’t reach. At Colorado Fleetworks, we’ve got two of the tallest paint booths in the Denver metro area, and bays built to handle high-roof vans and larger fleet vehicles. That means we can take care of everything from basic fender repair to full panel replacements and full-body paint jobs, no weird workarounds or sketchy corner cutting. Vans Have More Going On The other thing with van body repair is that it’s rarely as simple as “pop off the bumper and replace it.” If your van’s a camper, you might have cabinets, plumbing, wiring, or custom panels in the way. If it’s a work van, you’ve probably got shelving, racks, or tool systems built in. A shop that knows vans understands how to remove interior components without destroying your setup. We know how to get the job done while protecting the stuff you’ve built around it. Paint Jobs That Actually Work Painting a van isn’t just about matching color. It’s about space. You need the kind of airflow, ventilation, and vertical clearance that a shop with oversized booths can provide. Trying to spray a tall van in a short booth is a no-go. You’ll get overspray, inconsistent coats, or worse, a job that peels or fades in a few months. With our equipment, we can get that even, factory-quality finish no matter the size of your van. Bottom Line If you’ve got a van that needs body work , don’t waste your time at a shop that isn’t built for it. Find a place that actually has the right equipment, knows how to work with large vehicles, and respects the setups inside them. At Colorado Fleetworks, we’re set up to handle everything from Transit Connects to high-roof Sprinters , and we do it every day. If your van needs body work in the Denver area, we’re ready when you are.

Replacing the engine in your Mercedes Sprinter isn’t anyone’s idea of fun, but if you’re her asking "How much does a Sprinter engine replacement really cost?," you might be staring that reality in the face. Whether you're running deliveries every day, living full-time in your van, or just trying to keep your work fleet on the road, a blown engine is a big deal. And yes, it can be a big price tag too. So… what’s the damage? Let’s get to the part everyone wants to know. On average, a full engine replacement for a Sprinter can run anywhere from $10,000 to $20,000. That’s a wide range, but there’s a reason for it. It depends on: The year and model of your Sprinter Whether you go with a brand-new engine, a remanufactured one, or a used swap Labor costs, which vary depending on where you take it How much additional work is needed once the engine’s out For example, if the turbo is cooked or you’ve got other damage tied to the failure, that could bump up your costs. Why labor costs are a big factor Sprinters aren’t like your typical pickup or sedan. Everything’s packed in tight under the hood, and getting to the engine takes time. There’s also a whole lot of sensors, electronics, and van-specific parts to reconnect after the new engine is in. It’s a time-consuming job that really needs a tech who knows these vans. New vs. remanufactured vs. used Sprinter engines A brand-new engine from Mercedes is the most expensive route, and not always necessary. Many folks opt for a remanufactured engine, which has been rebuilt with new internal components and tested. It's usually more affordable and still super reliable when sourced right. Some go the*used engine route, but it’s riskier unless you really know the history. Should you replace or repair? Not every engine issue means full replacement. If the bottom end’s still solid and you’ve just got a cracked head or blown gasket, repairs could be more cost-effective. But if your Sprinter’s racked up a ton of miles and it’s one thing after another, a full swap might actually save money long-term. Trust a Sprinter expert, not just any mechanic We’ve said it before, and it definitely applies here: not every shop is set up to handle Sprinters the right way. You need someone who understands these vans inside and out. At Colorado Fleetworks, we work on Sprinters every single day , including work vans, camper builds, delivery vehicles, you name it. We’ve done our fair share of engine replacements, and we’re honest about what makes sense and what doesn’t. If you’re facing a possible engine replacement, we can walk you through the options, take a real look at what’s going on, and help you make the call that’s right for your van and your budget.

Winter driving in Colorado isn’t for the faint of heart. One day, the roads are dry and clear, and then overnight, you’re waking up to black ice and a foot of snow. If you’re still running all-season tires, you might be rolling the dice more than you realize. Here’s why winter tires are a game changer for safety and control when the temperatures drop. What Makes Winter Tires Different? Winter tires aren’t just about tread patterns - they’re made from a different type of rubber that stays flexible in the cold. Regular all-season tires harden in low temperatures, reducing grip, while winter tires keep their traction even in freezing conditions. Plus, their deep grooves and biting edges are designed to cut through snow and slush, helping you stay in control. Do You Need Winter Tires in Colorado? Short answer: Yes, if you want to drive safely in snow and ice and don't have other traction devices. Colorado’s winter roads can be unpredictable, and while all-wheel drive helps with acceleration, it won’t help you stop faster. Instead, your tires do that. If you drive in the mountains, winter tires can make the difference between getting up a pass or sliding backward. Even in the city, icy intersections and surprise snowstorms mean having the right tires could prevent an accident. The Colorado Traction Law If you’re driving in the mountains from September to May, you might already know about Colorado’s traction laws. When these go into effect, vehicles must have proper tires with at least 3/16" tread, snow chains, or a four-wheel/all-wheel drive system. You can view all of the up-to-date requirements here . Winter tires (or all-terrain tires with the right tread depth) make it easier to comply with these laws while also keeping you safer on the road. When to Switch to Winter Tires The best time to put on winter tires is before the first big freeze, typically around October or early November. A good rule of thumb? When temperatures consistently drop below 45°F, it’s time to swap them on. Once spring hits and the weather warms up, switch back to all-season or summer tires to prevent unnecessary wear on the softer winter rubber. Need Help Getting Winter-Ready? At Colorado Fleetworks, we know how important it is to keep your vehicle safe and reliable all year long. If you need winter tires installed or aren’t sure if your current ones are up to the challenge, we’re here to help. Swing by, and we’ll make sure you’re set up for whatever Colorado’s winter throws at you!

Winter is tough on vehicles, and the last thing you want is to deal with a dead battery or sliding around on icy roads. A little maintenance now can save you a lot of hassle when temperatures drop. Here’s what to focus on before winter really sets in. Check Your Tires Tires are your first line of defense against winter roads, so make sure they’re in good shape. Check the tread depth—if it’s worn down, you might need new ones. If you live somewhere with heavy snow and ice, winter tires are a smart investment since they provide better traction. Also, colder temperatures cause tire pressure to drop, so check it regularly and keep it at the recommended PSI. Test Your Battery Cold weather drains car batteries faster, and if yours is already weak, it might not have enough power to start your vehicle. If your battery is more than three years old, get it tested before winter hits. Also, check for corrosion on the terminals, since buildup can interfere with the connection. If you notice slow starts or dimming headlights, it might be time for a replacement. Keep Up with Oil Changes Winter temperatures make oil thicker, which can strain your engine. Check your owner’s manual to see if your car requires a different oil viscosity in cold weather. If you’re due for an oil change, don’t put it off—clean oil helps your engine run smoother, especially in freezing conditions. Inspect Your Brakes Slippery roads mean your brakes need to be in top shape. If you’ve noticed any squeaking, grinding, or a spongy brake pedal, get them checked out. Worn brake pads can reduce stopping power, which is the last thing you want when roads are icy. Keep Your Fluids Topped Off Antifreeze (coolant) keeps your engine from freezing, so make sure it's at the right level and mixed correctly. You’ll also want to check your windshield washer fluid and switch to a winter formula that won’t freeze. While you’re at it, inspect your wiper blades—if they’re streaking or skipping, replace them so you can keep your windshield clear in snow and sleet. Pack a Winter Emergency Kit Even with the best maintenance, breakdowns can still happen. Keep a kit in your car with essentials like an ice scraper, jumper cables, a flashlight, blankets, and extra gloves. If you travel in areas with heavy snow, consider adding a small shovel, kitty litter (for traction), and some non-perishable snacks in case you get stuck. Don’t wait until you're stranded to make sure your car is winter-ready. A little preparation now can keep you safer on the road and prevent unexpected breakdowns. If you need a winter tune-up or a battery check, bring your vehicle to Colorado Fleetworks and we can help. Stay safe out there!

If you drive a diesel, you already know they’re built for serious work. But come winter, diesel vehicles need a bit of specialty maintenance to keep them running strong. The cold brings unique challenges, and neglecting them could leave you stuck, or worse, facing expensive repairs. The big ones to pay attention to? Diesel Exhaust Fluid (DEF) and Diesel Particulate Filter (DPF) systems. These two are critical, but there are a few other key areas you’ll want to prep before winter hits. Here’s what you need to know. Diesel Exhaust Fluid (DEF) DEF is a must-have for modern diesel vehicles to reduce emissions. But here’s the kicker: it freezes at 12°F (-11°C). Make sure your DEF tank is topped off and that the system is working properly. If DEF crystallizes, it can cause clogs or damage to your system. Don’t let that happen, check it before the cold sets in. Diesel Particulate Filter (DPF) Your DPF traps soot to keep emissions clean, but in winter, it can be harder for the system to complete its cleaning cycle, especially if you’re making short trips. A clogged DPF means reduced performance and potential breakdowns. Keep your engine warm and running long enough for those regenerations to happen. Glow Plugs and Modules Glow plugs act like spark plugs for diesels, warming the engine cylinders so it can start. In the cold, worn glow plugs or a faulty glow plug module can make starting a nightmare. If your vehicle struggles to turn over on cold mornings, it’s time to get these checked. Winter Fuel and Anti-Gel Additives Diesel fuel tends to gel in freezing temps, turning waxy and clogging your fuel lines. Using winter-grade diesel fuel or adding an anti-gel treatment can help prevent this. Trust us, you don’t want to deal with gelled-up fuel when you’re already late for work or trying to make it to a job. Battery and Starter Check Cold weather drains batteries faster and puts extra stress on your starter. Diesels need strong cranking power to start, so if your battery’s already weak , it’s a good idea to replace it before winter hits. Clean terminals and a quick battery test can save you from being stranded. Is Your Diesel Ready for Winter? Winter can be hard on diesel vehicles, but a little prep goes a long way. At Colorado Fleetworks, we specialize in diesel maintenance , from DEF and DPF systems to glow plugs and winter-ready tune-ups. If you want to keep your diesel humming through the cold months, swing by. We’ll make sure you’re ready for whatever winter throws your way. Stay warm, and keep that diesel running strong!

Your battery may be the unsung hero of your vehicle, but it doesn’t last forever. As we head into winter here in Colorado, symptoms of a bad battery can get much worse. Cold weather reduces your battery's ability to hold a charge, and it can also slow down the chemical reactions inside, making it harder to start your engine. If your battery is already weak, the extra strain from freezing temperatures combined with increased power demands like running the heater, defroster, and lights could leave you stranded. Here are some clear signs it’s time for a replacement. 1. Slow Engine Start If your engine cranks slower than normal when you start the car, your battery could be losing power. This is one of the first warnings of a failing battery. 2. Dim or Flickering Lights A weak battery can’t power your vehicle’s electrical systems properly. If your headlights or interior lights dim, it’s a red flag. 3. Dashboard Warning Light Many vehicles have a battery-shaped light that appears when the system detects low voltage. Don’t ignore this—it’s there for a reason. 4. Corrosion on Battery Terminals Check under the hood. If you see white or blue corrosion on the battery terminals, it can interrupt the connection and cause performance issues. 5. Swollen or Leaking Battery A bloated or cracked battery case usually means it’s overheating or has internal damage. This can be dangerous, so get it replaced immediately. 6. Frequent Jump Starts If you’ve needed to jump-start your car more than once in a short time, the battery isn’t holding a charge properly. 7. Strange Electrical Issues Your radio resetting, power windows acting up, or the key fob not working consistently could point to a battery problem. Ready to Replace Your Battery? Most car batteries last around 3 to 5 years. If yours is older and showing any of these signs, don’t wait for it to fail completely. A dead battery at the wrong time can leave you stranded. At Colorado Fleetworks, we know vehicle batteries inside and out. If you’re unsure about yours, we can test it and replace it along with any other winter maintenance your vehicle needs , helping you get back on the road with confidence.

If you’re looking for a van for work, deliveries, or life on the road, reliability is probably your biggest concern. The Ram ProMaster has earned its place as a popular option, offering some real advantages compared to other vans. In fact, the ProMaster is one of our favorite vans to specialize in repairing . How well do they hold up over time? Let’s break it down. Where the ProMaster Stands Out One of the biggest benefits of the Ram ProMaster is its front-wheel drive system. This design gives it better traction on wet or slippery roads and makes the van easier to maneuver in tight spaces. It also allows for a lower floor height, which is a huge plus if you’re loading tools, cargo, or even building out a camper. The ProMaster’s shape is another major win. With its square, straight walls and wide cargo area, you get more usable space than in other vans. Whether you’re installing shelves for work or trying to squeeze in camper van furniture, you’ll appreciate every inch of that boxy design. Compared to vans like the Mercedes Sprinter, ProMasters are also more affordable. They cost less upfront and are cheaper to maintain over time. Parts are easier to find, and repairs tend to be simpler since the ProMaster skips a lot of the premium bells and whistles. The Drawbacks to Be Aware Of No van is perfect, and the ProMaster has a few quirks. Transmission issues can be a problem in older models, especially if maintenance has been overlooked. Electrical systems are another area where trouble can pop up, so keeping an eye on any warning lights is important. The front-wheel drive, while great for city driving, isn’t ideal for rough terrain or off-road conditions. The ProMaster doesn’t have an all-wheel-drive option, which could be a downside if you spend a lot of time in snow or on unpaved roads. How to Keep a ProMaster Running Strong Like any van, reliability depends on how well you take care of it. Regular oil changes , transmission services , and chassis maintenance go a long way toward extending the life of a ProMaster. It’s also worth sticking to a consistent service schedule, especially if you use the van for heavy-duty work or long trips. If you’re using a ProMaster as a camper, be sure that any build-out or modifications don’t interfere with key systems like wiring, brakes, or the transmission. A good van mechanic will know how to work around those setups without causing damage. Are ProMasters Reliable? For most owners, yes. ProMasters are dependable when they’re maintained properly, and they’re an excellent choice for anyone who needs a spacious, practical van that won’t break the bank. They’re ideal for city driving, delivery routes, and budget-friendly camper conversions. If you’re looking for a rugged van that can handle extreme weather or off-road adventures, you might want to look at other options like a Sprinter or Ford Transit. But for everyday use and smart, affordable design, the ProMaster delivers. And if you’re ever in doubt about your van’s reliability, it helps to have a shop that knows what they’re doing. Vans have their own set of unique challenges, and the right mechanic can save you a lot of time, money, and headaches. If you're in the Denver area and needing service or maintenance, give us a call .
