2005 Duramax losing coolant... no apparent reasons...

125

Asked by cberci2692 Aug 07, 2011 at 10:31 PM about the 2005 Chevrolet Silverado 2500HD LS Crew Cab LB 4WD

Question type: Maintenance & Repair

About a month ago my duramax started losing coolant, check radiator, water pump area and all hoses... can't find the leak. I also checked for traces of coolant in the oil.. evidence of a blown head gasket, but no success. I am running out of ideas.. losing between a liter to two liters of coolant a week...

Any help or advice will be greatly appreciated!

Thanks in advance!

This model year is notorious with coolant leaks. Its the heads of your truck. If it has a blown gasket, it will leak coolant. Just read it in Diesel Power Magazine last month. They did an article about it.
