How to Diagnose a Blown Head Gasket
As a Certified master technician, sometimes diagnostics require specialized equipment and a lot of in depth testing. Sometimes it just requires some knowledge.
Today we are going to show you how to quickly diagnose it. We placed a glove over the radiator and it expanded when we attempt to start the truck. The reason this happened is the combustion from the piston got into the radiator and its not supposed to do this but the head gasket is blown. So if the glove waves at us, it is a blown head gasket. This is just one of the ways we can diagnose a blown head gasket, this one happens to be pretty severe.
