ISR Performance Silicone Radiator Hose - Nissan 240sx KA24 - Black

The ISR Performance black silicone radiator hoses for the Nissan 240SX KA24 are the low-key option in ISR's silicone hose line for the KA engine. They replace the original rubber radiator hoses with silicone designed for a wider range of heat and coolant pressure, finished in black so they blend into the bay.

What you get over rubber

Silicone has much higher strength than the OEM rubber hose, which prevents the hoses from expanding when the system is pressurized and keeps them from softening or splitting as they age. On a 240SX that is well over twenty years old, replacing these hoses removes a common failure point before it strands the car.

Application

• Nissan 240SX, KA24 engine
• Color: black
• Blue version also available from ISR

Fitting

Drain the cooling system, swap the hoses with fresh clamps, and refill and bleed with new coolant. Consider pairing with an ISR aluminum radiator and fan shroud kit for the KA24 to finish the cooling system in one pass, and give the clamps a final check once the engine has been through a few heat cycles.

All ISR Performance products are designed for off-road use only.
