Product Description

Stock transmission coolers are fine for everyday driving but struggle under heavy use. Tube-and-fin cores like the factory cooler rely on thin metal tubes and fins to shed heat. This works until your truck is towing, carrying heavy gear, or loaded for overland adventures. Roof-top tents, armor, bigger wheels and tires, and extra cargo all add load that generates heat in your transmission.

This is where a stacked-plate core makes a real difference. With far more surface area and improved fluid flow compared to tube-and-fin designs, it dissipates heat more efficiently. Lower transmission fluid temperatures mean less wear on your transmission and more confidence that your Xterra or Frontier can handle towing, off-road trails, or fully loaded overland trips.

Two performance levels:

The standard cooler utilizes a compact 19-row core, offering ample fluid cooling performance for street-driven trucks where maximum cooling is not required. Also works well with vehicles that require more space for other coolers in front of the core support, particularly with Z1's Supercharger Kit.

An optional upgrade is available featuring a MASSIVE 34-row core, providing the most fluid cooling capability. Perfect for trail rigs with lots of load, of vehicles that are primarily used for towing.

Regardless of choice, either core option will provide notable increases in cooling system performance compared to the factory 16-row tube-and-fin core.

Features:

  • Provides more stable transmission fluid temperatures
  • Durable Pro-Cooler, available in two sizes
  • 100% bolt-on installation - no modifications necessary!

Fits:

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

Install was pretty straightforward. However there wasn’t enough room to keep my winch installed. I am running a Coastal Offroad front bumper. With how much wider the new cooler is, there really wasn’t any way to keep the winch installed there. Also I had to modify my grill quite a bit to get that to fit back into place as well. Temps seem to be running cooler but I haven’t gotten to do any steep mtn passes yet.

For a 19 Row cooler, it does pretty well over the Factory Cooler. If anything I have noticed that it sheds heat a bit quicker. That said for my setup I wish I would have gone with the 34 Row instead. If your vehicle is heavy or has a Bull Bar, I would would go with the 34 Row.

Very easy installation as the instructions are well written with many photos. It took me maybe 90 minutes to take out the stock cooler and install this one. Make sure you have a 12mm hex socket to tighten the banjo bolts. I also used a 5/16in brass barbed connector to connect the included return line hose to the stock return line hose. This is an easy item to install as everything fits perfectly.
