- Removed Thermostat and bench tested found that Thermostat is opening at 185 F degrees and not defective. Warranty of thermostat and installed new one. With further diagnostic checks found that engine is still getting hot and over-heating. Cause is that over 54/hc in cooling system head gasket and also leaking water pump are at fault and causing to munch air to be in cooling system not allowing thermostat to open. Will need to replace head gaskets to solve over-heating problem. Continued operation of vehicle while overheating will cause headgasket to fail.
