ISR Performance S13 SR20DET Water Pump and Combo Kit - Nissan 240sx

If the water pump on your S13 SR20DET is due, this ISR Performance combo kit handles the rest of the cooling system at the same time. It packages the OE replacement water pump with a 60 degree thermostat and a black silicone radiator hose set, so brittle factory hoses and a tired thermostat come out while the coolant is already drained.

Why do it together

• Replacing the pump means draining the system anyway; the hoses and thermostat add little labor
• Old factory rubber hoses on a swapped SR are often hard and cracked
• The lower opening temperature of the 60 degree thermostat helps bring water temperatures down on a turbocharged engine

Kit includes

• ISR thermostat, Nissan SR/KA, 60 degree
• ISR OE replacement water pump, Nissan SR20DET S13
• ISR silicone radiator hose kit, Nissan SR20DET S13/S14, black

Install tips

Clean the block mating surface completely before fitting the new pump, use fresh coolant, and burp the system thoroughly after refilling. Recheck hose clamps after the first few heat cycles since silicone can relax slightly.
