ISR Performance Silicone Radiator Hose Kit Nissan 370z 2009+ - Red

Red ISR Performance silicone radiator hoses for the 2009 and newer Nissan 370Z, sold as a kit to replace the original rubber hoses in one go. Stock hoses on a Z34 are fine when new, but years of heat cycling leave them soft and prone to weeping at the clamps. ISR builds these from two layers of silicone so they tolerate a wider band of heat and coolant pressure than the OEM style hoses they replace, keeping the VQ37VHR cooling system reliable under hard use.

Construction details

• Two-layer silicone build for strength at temperature
• Designed to handle more coolant pressure than factory rubber
• Resists heat degradation, so the hoses stay pliable instead of cracking
• Red finish for an engine bay that reads as deliberately built

Vehicle fitment

Nissan 370Z, Z34 chassis, 2009 and later. This listing covers the red kit. Black and blue versions are also available for most applications.

Install tips

Have fresh coolant on hand, since the system has to be drained to change the hoses. Clean the hose necks before fitting the silicone so the clamps can seal against a smooth surface, and recheck clamp tension after the first few heat cycles. The kit weighs about 2.5 lb.
