Frequently Asked Questions (FAQs)

1. How do you know if your thermostat is bad in your car?

One of the first things you will notice is the temperature gauge is higher than normal. It may even start to fluctuate frequently. If you notice the gauge is hovering ¾ of the way from the top, then your thermostat is experiencing damage in the form of overheating. This can soon lead to your engine and car overheating.

2. How much does a car thermostat change cost?

Unfortunately, thermostats play an essential role in your car. So fixing a car thermostat will usually cost somewhere in the range of $200 to $300.

3. How do you know if your car thermostat is working?

Start your car's engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
