ISR Performance Silicone Radiator Hose - Nissan SR20DET - Red

Red hoses have been a staple of the SR20DET engine bay for a long time, and the ISR Performance red silicone radiator hoses give you that look with hose material that outperforms factory rubber. ISR's silicone-based coolant hoses are built to take a wider range of heat and coolant pressure than OEM-style hoses.

Material advantage

• Silicone strength well above OEM rubber, which prevents the hoses from ballooning under pressure
• Tolerates higher coolant temperatures and pressures
• Resists aging, so the hoses stay pliable rather than cracking
• Red finish stands out against a black or raw-aluminum bay

Compatibility

Nissan SR20DET, as found in S13 and S14 240SX swaps. ISR offers the same hose set in blue and black as well.

Installation advice

Drain the system first, fit new hose clamps, refill with fresh coolant and bleed the air out before driving. If you are upgrading to an ISR aluminum radiator at the same time, install the hoses with the radiator so the whole cooling system is new. Inspect the clamps again after a few heat cycles, since silicone can settle slightly on the fitting.

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