Product Detail
FITMENT: This Gates 170 - degree thermostat is specifically designed for Subaru WRX models from 2002 to 2014 and Subaru STI models from 2004 to 2021. FEATURES: Installing this thermostat in your vehicle is a game - changer! It optimizes engine performance and longevity. By lowering the engine's operating temperature, it prevents overheating, a big problem that can cause serious damage and expensive repairs. Running at a cooler temperature means more efficient combustion, better fuel economy, and fewer emissions. It also protects engine parts like gaskets, seals, and lubricants, extending your vehicle's lifespan. Plus, it boosts engine power and responsiveness. Cooler intake air increases the density of the air - fuel mixture, leading to better performance. GOING RACING! In racing, combining this 170 - degree thermostat with a high - flow radiator is a smart move. The thermostat keeps the engine cool during intense racing, preventing power loss, wear, and even failure. A high - flow radiator has larger coolant passages and efficient cooling fins for better heat dissipation. Together, they keep the engine in its ideal temperature range, maximizing performance and reliability. They also prevent heat - related issues and extend the life of key engine components.

Using this Gates 170 - degree thermostat is easy. First, make sure your engine is cool before starting the installation. Locate the existing thermostat housing in your Subaru WRX (2002 - 2014) or STI (2004 - 2021). Remove the old thermostat carefully and clean the housing. Then, place the new 170 - degree thermostat in the housing as per the correct orientation. Reassemble the housing and check for any coolant leaks. When it comes to maintenance, regularly check the coolant level. If the coolant is low, top it up with the recommended type for your vehicle. Also, keep an eye on the engine temperature gauge. If it shows abnormal readings, it could be a sign of a problem with the thermostat or other cooling system components. When going for long - distance drives or in hot weather, especially if you're using it for racing, ensure your high - flow radiator is in good condition. If you notice any issues like overheating or reduced engine performance, it's best to have a professional mechanic check the thermostat and the entire cooling system.
