Installation Notes and Tips

Verify fitment by matching the vehicle year, model, and connection style before installation. Inspect the surrounding hoses and fittings for wear, contamination, or damage while replacing the cooler.

For best results, flush the power steering system if contamination from the failed cooler is present.
