Diesel Vehicle Maintenance for Colorado Winters
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.
