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

Swap the tired factory rubber hoses on your 2009+ Nissan 370Z for this blue ISR Performance silicone radiator hose kit. It is a straightforward upgrade for anyone who has pulled a soft, bulging OEM hose off a VQ37VHR and would rather not do it again. The two-layer silicone is built to withstand more heat and higher coolant pressure than the stock rubber, which matters once the car spends time at full load on a hot day.

What the upgrade gets you

• Two-layer silicone that stays firm at operating temperature rather than ballooning
• Higher tolerance for coolant pressure than OEM style rubber hoses
• Better resistance to the heat that gradually degrades factory hoses
• Blue silicone that adds a clear visual accent to the engine bay

Compatibility

Fits the Nissan 370Z, Z34 chassis, model years 2009 and up. This is the blue kit; ISR offers the same hoses in black and red for most applications.

Before you install

Plan on a full coolant drain and refill, and inspect the radiator and thermostat housing necks for corrosion while the hoses are off. Use proper clamps sized for silicone rather than reusing stretched factory spring clamps, and bleed the system carefully once everything is back together. Kit weight is around 2.5 lb.

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