Engine Coolant Thermostat (105 Deg) by Aftermarket

Engine Coolant Thermostat (105 Deg) by Aftermarket

Your engine coolant thermostat sits between the engine and the radiator, in a thermostat housing. The thermostat blocks the flow of coolant to the radiator until the engine has warmed up. Once the engine is warm enough, usually around 200-220 degrees F, the thermostat opens and allows the coolant to flow. The engine coolant thermostat is the most common component of the cooling system to fail, which can cause your car to overheat in the unlikely event it were to be stuck closed. More commonly, the thermostat can be stuck open, making it difficult for your engine to warm up. This can result in your car running cool, causing an overly rich fuel mixture and an inefficient running engine. It should be replaced anytime you have major work done to the coolant system.

About Aftermarket

Aftermarket Logo

At, the term aftermarket is less of a brand and more of a philosophy. Whenever a manufacturer designs and builds their own version of OEM and OES parts, we consider them being built after the car hit the market. When you see a part labeled under the "Aftermarket" namesake, this means the actual brand of the part is shifting and cannot be guaranteed.

The quality of these parts should be expected to be on par with OES parts, but luckily for you, at a substantially more cost effective price. This is because we are constantly looking for different aftermarket brands that fulfill our quality benchmarks to put an one year warranty on, while featuring a price point that you can agree on.

Our aftermarket hardware is US sourced and of the absolute highest quality. We take your safety as well as your vehicle's reliability seriously. You never have to wonder if our hardware is mislabeled.

If this is not the exact Engine Coolant Thermostat (105 Deg) you are looking for, or you would like this part in a brand other than Aftermarket, please call us at (800) 467-9769 and one of our customer service experts will help you locate the exact part you need.
