ISR Performance Silicone Radiator Hose - Nissan SR20DET - Blue

The blue ISR Performance silicone radiator hose set for the Nissan SR20DET swaps the factory rubber coolant hoses for silicone pieces that handle a higher range of heat and coolant pressure. On an SR-powered 240SX, it is a simple way to add reliability to the cooling system and bring some color to the engine bay.

Silicone versus rubber

• Silicone has much higher strength than OEM rubber, so the hoses do not expand under pressure the way old rubber does
• Rated for higher temperatures and coolant pressures than OEM-style hoses
• Does not go hard, crack or soften with age the way rubber coolant hoses do
• Blue finish for a clean, coordinated look

Application

Nissan SR20DET. Commonly used on S13 and S14 240SX swaps. The same hoses are also available from ISR in black and red if blue does not match the rest of the bay.

Install tips

Replace the hose clamps while you are in there, drain and refill with fresh coolant, and bleed the system thoroughly. Silicone hoses are a natural companion to an aluminum radiator, so if the factory radiator is on its way out, consider doing both at once.
