Part #: OE - SR - WP - S13. This ISR Performance OE replacement water pump is a great fit for your Nissan SR20DET S13. Unlike OEM Nissan parts, these are OE replacement pumps, just like the ones you'd find at an auto parts store. It comes with a new gasket, and you'll need to reuse the stock studs. Note that it only fits the S13 SR20DET RWD models. Get reliable cooling performance with this water pump.

Using this water pump is easy. First, make sure your engine is cool. Remove the old water pump and carefully clean the mounting surface. Then, place the new gasket on the pump and attach it to the engine using the stock studs. Tighten the studs evenly. When it comes to maintenance, check the water pump regularly for any signs of leaks or unusual noises. If you notice any issues, it's best to get it checked out right away. Also, keep the coolant levels in check as proper coolant levels help the water pump work efficiently.
