Installation Notes and Tips
Verify the vehicle’s original cooler style, inlet and outlet connection size, and mounting layout before installation. Compare the existing cooler to Dorman 918-598 to confirm fitment on 2013-2017 Chevrolet Equinox and 2013-2017 GMC Terrain models. Inspect hoses and surrounding steering components for wear or leaks during replacement so the new cooler can perform as intended.
