What is a Car Thermostat?
A thermostat opens or closes a valve to control coolant flow between the car's radiator and engine. It responds to changes in temperature. The valve itself operates through a wax-container element. As coolant temperature increases, the fluid (or wax) container melts and enlarges, which, in turn, pushes a small bar, dividing a centre plate from its mounting base to expose the valve. The thermostat also helps to keep your engine running smoothly and reduces engine wear. Ensuring optimum fuel economy and harmful emissions.
If your car starts overheating quickly after starting it, or the dashboard temperature gauge drops below normal, it might be an indication that your thermostat has failed.
What is a Thermostat Housing?
The thermostat housing is where the thermostat is fitted to perform its operation. A broken housing might cause the thermostat to fail, which, in turn, could cause damage by overheating your engine.
How a Car Thermostat Works
Sitting between the engine and the radiator and usually connected to the upper or lower radiator hose, think of the thermostat as a valve that opens and closes to allow or prevent coolant from flowing to the radiator.
All thermostats have a temperature rating at which they open or close, and the rating can differ from vehicle to vehicle based on the manufacturer's specifications. Most thermostats are rated to begin opening between 180 and 195 degrees and will reach the full open position around 20 degrees higher, allowing coolant to flow between the radiator and engine.
Problems a Thermostat Can Experience
The thermostat isn't a maintenance or wear-related item that requires replacement at any pre-set level. Instead, it's usually only replaced if failing, or whenever the water pump is replaced. The main problems a thermostat can experience are being stuck open, stuck closed, or leaking.
1. Thermostat Stuck Open
If the thermostat is stuck open, an optimal engine temperature is never going to be reached, and there will be no or little heat available in the passenger compartment, and engine wear can increase.
2. Thermostat Stuck Closed
If it's stuck closed, the engine is going to overheat because coolant isn't moving to the radiator. Debris or a broken spring in the thermostat could be responsible for it being stuck in either the open or closed position.
3. Leaking
Finally, the thermostat housing can fail and begin leaking coolant.
Signs of a Bad Thermostat
At the very least, a periodic visual inspection should be conducted under the hood and under the car to look for signs of leaking coolant. Another alternative is to actually test the thermostat by removing it from the vehicle and placing it in a pot of boiling water. If the thermostat opens in the water, and then closes when removed from the water, it's working. Other warning signs indicating a faulty thermostat include:

Pro Tip
Take a look at the coolant/antifreeze first. If it looks dirty, it should be flushed. It would be a good idea to flush with the old thermostat still in, or removing it to complete the flush.

FAQs About Thermostat
Q: Why Should You Replace a Bad Thermostat?
A: Aside from maintaining the engine’s optimal performance, getting a new thermostat reduces the risk of overheating and thermostat failure. Experts recommend changing the thermostat every ten years for preventive maintenance, especially on early-model and high-mileage vehicles.
Q: Can You Drive Without a Thermostat?
A: It is not advisable to run your engine without a thermostat. While driving without a thermostat almost never causes overheating, it does increase the risk of sludge formation due to the engine running too cold, and sludge in the oil pan can starve the engine for oil.
Q: Is it Safe to Drive with a Bad Thermostat Housing?
A: Although it’s possible to drive with a damaged thermostat housing, it’s highly recommended that you don’t. Ignoring a coolant leak is flirting with disaster, and cooking your engine can ruin your whole day. It’s best to enlist the help of a mechanic to check your thermostat and replace the faulty parts as needed. You don’t want to wait until your vehicle overheats, potentially causing catastrophic internal engine damage.
