Product Description

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.

The CSF Dual-Row Drop-In Radiator is constructed of Aluminum and does not have the plastic caps that are prone to busting under high pressure. Having Dual Rows in this radiator will ensure the temperature of your coolant stays cooler than the OEM single row radiator.

Coupled with the CSF 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.

NOTE: The Radiator Cap supplied on this CSF radiator is not compatible with all models. It is recommend to transfer your OEM radiator cap from your previous radiator to prevent overheating. It may be necessary to bend the tabs on your OEM radiator cap for installation.

Kit Includes:

Optional:

* We recommend using the OEM Long Life Blue Coolant (Antifreeze) Not Included

Fits:

  • 2005-2019 Nissan Frontier
  • 2005-2012 Nissan Pathfinder
  • 2005-2015 Nissan Xterra

Much better upgrade than the plastic trimmed factory one that cracked on me.

Operates as advertised! My 06' Xterra runs much much cooler during operation with the Mishimoto thermostat combination. The red silicon tubes look great! The radiator looks great too, nice and shiny; solidly built.

Really high quality. Not a difficult job, but zero instructions. Lots of stickers, no instructions ( had to search for the overflow tank hose location). I did the heater core bleeder at the same time.
