Subaru WRX STI Water Pump

Keeping your WRX STI in top shape is your top priority.

Auto enthusiasts appreciate the a variety of optional equipment built into each Subaru, and know that only top quality repair WRX STI parts will suffice when your car or truck needs fixing. Your Subaru dealership isn't the only place to locate the highest quality parts to repair your WRX STI. It's not every day that you discover you need a replacement Water Pump to fix your automobile. Anyone who owns a Subaru knows that when it comes to repairing their car, truck, or SUV only the highest quality replacement parts will do.

Why Water Pump replacement is so important.

Your Subaru WRX STI uses liquid coolant to maintain a constant temperature in the engine, and at the heart of that engine is the water pump. It turns along with the crankshaft via a belt that connects pulleys on each part. Along with the thermostat, coolant hoses, and radiator core, your Subaru WRX STI water pump continuously recirculates the water and ethylene glycol mixture through the engine; keeping it operating at a manageable, pre-determined temperature. If it fails, then the coolant temperature will soar and your engine block or cylinder head will crack.
