ISR Performance S13 SR20DET Water Pump Combo

If you're pulling the water pump on your S13 SR, you're already deep in there. Smart move to swap the brittle factory hoses and tired thermostat while everything's apart. This combo packages all three together so you only pay shipping once and you're not chasing parts mid-job.

What It Does

Bundles the three cooling system components that should always get changed together on an S13 SR20DET refresh: water pump, thermostat, and full silicone hose kit. The 60-degree thermostat opens earlier than stock, which helps keep coolant temps in check during hard driving. Silicone hoses replace the original rubber lines that get hard and crack with age.

Fitment

Nissan 240SX S13 (1989 to 1994) with SR20DET swap. The water pump and thermostat also work on KA-equipped cars. The included silicone hose kit is the S13/S14 black variant for SR20DET applications.
