Your car’s temperature is controlled by a thermostat that turns on the cooling system when it gets too hot.
The engine must run cool to avoid damage and maintain optimal performance.
However, if your thermostat is faulty, it can’t do its job, and you might have to replace it when the car starts cooling too quickly or not at all.
Common Issues of Thermostats
A common issue with car thermostats is that they become clogged with deposits from the mineral oil used in the engine.
When this happens, the metal blade inside the thermostat doesn’t move properly, so the coolant isn’t turned on or off as needed.

However, if your thermostat is faulty, it can’t do its job, and you might have to replace it when the car starts cooling too quickly or not at all.
Another common problem is when the thermostat fails to open and close properly.
When this happens, the coolant can’t circulate through the engine, which causes it to overheat.
A thermostat is a simple device that consists of two metal plates separated by a sealed chamber filled with liquid coolant.
When the engine starts heating up, the thermostat senses the temperature change and allows the coolant to flow between the plates.
This circulation keeps the engine at its ideal temperature. When replacing a thermostat, get one designed for your car’s make and model.
Some thermostats are specific to certain engines and won’t work if they aren’t compatible with yours.
Replacing a Faulty Thermostat
Car thermostats are located near the engine and are easy to access. You can replace it in about two hours with basic tools like a socket set, ratchet, and extension bar.
When replacing your thermostat, ensure you have all the necessary tools and replacement parts before working on your car.
Thermostats are pretty easy to install, but if you’re unsure how to do it yourself, get help from a friend or family member familiar with auto repair.
If you prefer to have a professional mechanic replace your thermostat, then be sure to have them diagnose the issue first so they can determine which part is causing the problem.
Things you’ll need:
- New thermostat (make sure it’s for your car)
- Ratchet set
- Socket set
- Flashlight or torch
- Coolant + water hose pipe sealer
- Oil filter wrench
- Jack stands or sturdy blocks
If you’re not ready to tackle this project, bring your vehicle to your local mechanic for diagnostic assessment.
Expert technicians can estimate how much it would cost to repair your thermostat and get your car back on the road as soon as possible.
If your thermostat is still working but not cooling enough, try lowering the temperature setting on your AC unit.
This can help reduce the strain on your engine and prevent overheating. If your thermostat is faulty and causing the engine to overheat, you must replace it.
This repair shouldn’t be taken lightly, as it involves removing and replacing the old thermostat with a new one designed for your vehicle.
Once you’ve gotten your car back on the road again, keep an eye on your thermostat to make sure it’s working properly.
If you’re experiencing overheating problems or notice that the AC is not cooling enough, then have your vehicle checked out by a mechanic right away.
Besides the thermostat, other things that can make your car overheat are hoses, fan belts, and radiator fans.
If one of these parts fails, it can cause your engine to work extra hard, leading to overheating problems.
Clogged coolant passages in the block or head are another common problem that causes engines to overheat.
When this happens, coolant can’t circulate freely through the engine, which can also lead to leaks.
