What It Helps Address

Installation Notes and Tips

Verify available space, hose routing, and connector style before installation. This cooler uses male 3/8 hose barb fittings and does not include a bracket, so mounting location and line routing should be planned before assembly. Confirm the vehicle’s transmission cooler line size and inspect surrounding condenser or radiator components for clearance.

For best results, flush the transmission cooler lines before connecting the new unit and check for leaks after startup. Confirm fitment against the specific year, make, and model listed for your application, including Nissan Armada, Ford F-150, and GMC Sierra coverage.
