ABSTRACT:
An engine coolant thermostat for an internal combustion engine is provided with pressure release blowout plugs in the event that a thermostat should fail. These plugs may be formed from a fibrous material and in one embodiment, a dye is released to color the engine's coolant so as to indicate that the thermostat has failed. Further embodiments envision the use of umbrella-like strainers threadably attachable to the top of the thermostat, and these strainers may be periodically inspected to determine the type of debris and residue present in the engine's coolant.
