Watch this video as barry wilson explains the importance of choosing the correct thermostat for a classic car or truck engine.

Car thermostat temperature range.

A thermostat stuck in the open position constantly pushes coolant into the engine and causes a lower operating temperature. This can range between 195 degrees fahrenheit and 220ºf. Your thermostat will typically be wide open when the temp reaches 20 degrees above the rating. Or replace it if necessary.

Without a thermostat your engine won t get to the operating temperature the computer is looking for so it will think the engine is cold and enrich the fuel mixture to help warm the engine.
