2006 Chevy Silverado 2500HD Duramax Coolant leak

Asked by Oct 26, 2016 at 11:14 AM about the 2006 Chevrolet Silverado 2500HD LT2 Crew Cab SB 4WD

Question type: Maintenance & Repair

Every 3-4 days my low coolant light comes on and there's not a visible coolant leak although you can smell it after its ran for awhile probably burning off. All pressure gauges in the truck have read fine and my oil level hasn't changed or show any water or coolant mixed in it. I've read where it could be a water pump or head gaskets. The water pump isn't making any crazy sounds although I guess it could be leaking slightly on the bottom side and burning off the engine ( I hope). What is probably the case? (Hopefully not head gaskets).

More than likely head gasket. I am in the process of replacing my head gasket now because of an external leak. But that is more than likely your leak. Possible the turbo.

I hope your wrong but I guess I'll have to swallow the pill either way it goes.

head gasket you would start getting white smoke and the radiator would be over flowing because of back pressure. trace leak is all i can say with what little info, sorry
