Symptoms of a Bad Heavy-duty Engine

White Smoke

If you notice that white smoke is coming from your exhaust, chances are you have a blown head gasket. Head gaskets tend to blow when your engine overheats for a prolonged period of time. If left unchecked, a blown head gasket may lead to further damage. White smoke is usually accompanied by coolant loss, poor performance, and poor fuel efficiency.

Rough Idle

If your truck is idling very roughly, chances are you have a damaged EGR valve. This is especially common on Cummins engines. When an EGR valve is damaged or stuck open, all of your exhaust is being recirculated into your combustion chamber. This means your truck isn’t getting enough oxygen, hence the rough idle.

"I took my 45' diesel motorhome to AZ Fleet for 75,000 mi. service. They performed all the requested services in a careful timely manner. Both of these issues were of great concern to us as we live fulltime in the motorhome and we are traveling over 10,000 mi. this summer"
