WHY TO BUY?
It is crucial to keep your engine at optimal temperature. If your motor stays too cold it will operate inefficiently and your heater will function poorly, but if it gets too hot your motor can be severely damaged. The job of thermostats is to regulate engine temperature. While factory thermostats usually work well, they are a common wear and tear item that will fail over time. Here at Andy's Auto Sport we have a full selection of replacement thermostats for you to choose from. Available in a host of different temperature ranges thermostats are very reasonably priced, and you are sure to find the perfect unit for your application in our lineup.
DID YOU KNOW?
A thermostat is a cleverly designed device. It is essentially a temperature sensitive valve. When your engine is cold the valve stays shut, keeping the coolant circulating in the motor so that it heats up quickly. But when the engine temperature reaches the thermostats preset level, the valve opens allowing coolant to circulate through the radiator to prevent overheating. It is possible to change to a higher or lower temperature thermostat depending on your requirements. If you want more heat from your heater, a higher temperature thermostat is often a great way to go. However if you want to reduce the chances of overheating in hot climates, running a lower temperature thermostat is preferable.
FAQ's
Q: What is a thermostat? Why buy a thermostat?
A: A thermostat is a unit that sits between the engine and the radiator. The thermostat blocks the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature, the thermostat opens up. Aftermarket performance thermostats open up at a lower temperature than a factory unit allowing the coolant to flow through your engine sooner, reducing coolant temperatures. If your vehicle's cooling system is efficient, you're less prone to overheating when putting you car through extreme performance measures.

Q: How do you install a thermostat?
A: A thermostat is installed by removing the thermostat housing unit. Once removed you can replace the factory thermostat with the aftermarket unit and help your engine cool off faster.
