Installation Notes and Tips

Verify the vehicle’s build date and connection style before installation. This cooler uses 0.31 in. hose clamp inlet and outlet fittings, so the existing hose routing and clamp condition should be inspected during replacement. Confirm fitment for 2014 Infiniti QX60 models built from 11/2013, as noted in the application data. For best results, flush the transmission cooler lines and check for debris before placing the new cooler into service.
