How to Spot a Broken Car Thermostat

How to Spot a Broken Car Thermostat

The thermostat and the water pump work together to ensure that the engine has enough coolant to operate at temperatures below 220 degrees Fahrenheit. When your thermostat needs to be replaced, take it to an auto repair shop. If you notice any of the following signs of thermostat failure, give us a call to schedule an appointment.

Corrosion on the Thermostat

If coolant is seeping out of the thermostat valve, one of the first things you may notice is that the thermostat will corrode. This valve opens and closes as needed to send coolant to the engine. If the valve becomes stuck in the closed position, a slow leak can occur. As a result, the coolant will begin to eat away at the metal housing of the thermostat as it puddles around it. At this stage of corrosion, changing the thermostat prevents a larger coolant leak.

Leaking Coolant on the Floor

There will be puddles or spots of coolant on the garage floor if you have a larger coolant leak. This indicates that the coolant has eaten its way through the thermostat, and the thermostat is now releasing the coolant. When you drive your car, truck, or utility vehicle, the engine may overheat due to the larger coolant leak. The thermostat, unfortunately, cannot be repaired. You will have to replace it because it’s corroded beyond repair.

Unpredictable Changes in Temperature

Unfortunately, the thermostat may begin to incorrectly read the engine’s temperature and release the coolant at an inopportune time. This will result in unusual temperature fluctuations in your engine, which you will be able to see on the temperature gauge. The engine will frequently alternate between running too cold and running too hot. If this is the case, you’ll need a new thermostat.
