Water Pumps

Water Pumps: the part that keeps coolant moving and heat out of your engine

A water pump is the heart of your cooling system. Driven off the belt or timing drive, its impeller pushes coolant through the block, up into the head, and out to the radiator so heat has somewhere to go. When the impeller wears, the shaft bearing gets noisy, or the weep hole starts leaking, temps climb and the job only gets worse. Replacing tired water pumps before they fail is cheap insurance against a warped head or a cooked engine, and if you already have the front of the motor apart for a timing job, it is the right time to do it.

What ThreePiece stocks

There are 34 water pumps in this category right now, spread across 11 brands. Gates leads the count, followed by Mishimoto, with Bosch, Edelbrock, Ford Racing, ISR Performance, Snow Performance, AMS, Aeromotive, Hot Rods and QuadBoss also represented. Current in-stock pricing runs from $51 to $604 - that is the live range for what is on the shelf, not a fixed quote. Coverage in the fitment data spans model years from 1989 to 2021, across makes including Ford, Nissan, BMW, Infiniti, Subaru, Mitsubishi, Honda, Kia, Chrysler and Polaris, plus powersports names like Kawasaki and Suzuki.

How to choose

The main decision is OE-style replacement versus a performance or specialty pump. A direct engine pump like the Gates EJ25 pump for Subaru Impreza, Legacy and Outback or the Mishimoto N54/N55 pump for the BMW 335i and the Mishimoto N20 pump for the F30 is the straightforward path when you are restoring cooling to stock. Performance builds and forced-induction setups have different needs: the Ford Racing 5.0L/5.2L performance pump kit targets the Coyote crowd, the AMS VR30 intercooler water pump kit for the Infiniti Q50 feeds an air-to-water intercooler rather than the engine, and the Aeromotive high-flow remote-mount coolant pump is a universal 27gpm unit with 3/4 NPT ports for custom plumbing. Match the pump to the exact job - engine cooling, intercooler circuit, or standalone electric flow - before you match it to price.

What else you need with it

Do the cooling system as a system. A worn pump often lives next to a tired radiator, and a coolant-passage job means fresh head gaskets or a full gasket kit. Plumbing an electric or intercooler pump pulls in fittings and adapters. Browse the rest of the Engine Components section to round out the build.

Fitment and ordering

Only some of these pumps carry model-specific fitment, so confirm the part matches your engine before you buy. If you are not sure, call fitment help at 813-535-5801 or reach us through our contact page. Every order ships free, and Affirm and Katapult financing is available at checkout.
