What would cause head gasket failure on a na truck? My truck has 255k and when you lift the hood it looks like a new engine... no leaks all the paint still on the engine. The truck has tons of new parts including a new water pump, thermostat, and new fan clutch. Would not flushing the coolant cause a hg failure? The older gentleman i bought it from was on top of maintenance.... hopefully I can find my sd card so I can upload some pics off of my phone.
