Z1 Off-Road Cooling Upgrade Kit for the Nissan Frontier / Xterra / Pathfinder models equipped with the 4.0L VQ40 powertrain. This upgrade kit will keep your engine running at a lower temperature whenever under excessive load.
At the heart of this Z1 Performance Aluminum radiator is a massive 42mm core (60% thicker than OEM), the thickest core that will properly fit in the factory core support. The increased core thickness provides substantially greater coolant volume and surface area, allowing for improved heat dissipation under heavy loads, high ambient temperatures, towing, off-road use, or forced induction applications.
Coupled with the Z1 Performance Radiator is the Z1 Silicone Radiator Hose Set that is unlike the conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack this silicone hose will stay soft and never degrade. (Please select your preferred silicone color before adding to cart)
The Mishimoto Low-Temperature Thermostat opens at 62°C / 144°F , rather than the OEM Thermostat which opens at Opens @ 177° - 182° F , which will reduce and maintain cooler engine temperatures under excessive loads. New upper and lower radiator mounts are included to ensure your newly upgraded radiator will not be damaged by your old worn-out rubber mounts.
This OEM Upgraded Thermostat is originally from the 2003-06 Nissan 350Z and features the same fit as as the standard Thermostat for the VQ40 but with a lower opening temp of 170° F compared to the factory VQ40 177° - 182° F opening.
