Car Thermostat Replacement Cost

The engine’s thermostat is responsible for monitoring and regulating the flow of coolant. The physical valve blocks or allows this flow depending on if it has reached a designated temperature, which determines how quickly your car will warm up.

This thermostat will help ensure your car engine is at the perfect temperature to operate efficiently. Once you start up, it ensures that all coolant reaches a safe temperature so that there are no overheating problems.

Car thermostat repair details

Before a mechanic will deem the thermostat as the only faulty part, they’ll want to inspect your entire cooling system. They’ll start with checking all of its parts including hoses and fans – before finally examining engine codes in case you’re facing engine issues. In cases where leaks are suspected or it’s clear that some hoses are deteriorating due to wear and tear, mechanics would recommend new hoses for stronger protection against coolant loss. When the mechanic tests your engine, he or she will check its temperature and thermostat’s opening. If the sensor indicates that it is running hotter than usual, then they’ll inspect for more signs of damage to see if this is more than just a problem with your thermostat.

To replace the thermostat, first, drain all of the coolant from your vehicle. You will then need to remove both the thermostat housing and the actual thermostat entirely in order for a new one to be installed properly. If you’re working on an engine that has a modern-day type of heating system – the thermostat and its housing will usually be a single part.

Once removed, the surface in-between the housing and engine will be cleaned before new gaskets are inserted. A replacement thermostat is then installed along with a fresh coolant refill which typically takes about 60 minutes for most vehicles to complete.

Typical signs of a faulty car thermostat

When a thermostat fails to work, it often remains open and the engine is allowed to run cooler than usual. If this happens then your “check engine” light may illuminate as well. However, in some cases, you might see poor gas mileage or even notice that your heater only blows cool air without any heat coming out of it at all.

If the thermostat remains in the closed position, this means that coolant will not be signaled to make its way to your engine. This can cause it to overheat and if left untreated may result in a blown head gasket or worse yet, a blown engine. Even if the thermostat is left on open, driving like this, without fixing it for too long could affect fuel efficiency and without proper heating capabilities, you won’t have heat inside of the car either. Get any issues fixed immediately before ending up with costly repairs down the line.
