In the freezing winter, you try to warm up with the heater, but the diesel heater just won’t start. Don’t panic—most of the time it’s not broken, just a few common issues.
First, check the battery. Diesel heaters are picky about voltage. If your battery is low, the heater won’t even try. A voltmeter in your car can save you trouble.
Next, check your fuel. If the diesel is dirty or mixed with water, it affects atomization and won't ignite properly. Cheap fuel can block the nozzle and cause white smoke.
Don’t overlook the air intake or exhaust. Blocked air intake or a clogged exhaust pipe will stop it from working. Always check before starting.
As for maintenance—it's simple. Wipe the case, check wiring, clean out carbon buildup after a winter’s use, and flush out the bottom of the fuel tank.
A little care now saves a lot of headaches later.
