Using this upper coolant pipe is easy. First, make sure your truck is turned off and has cooled down. Remove the old OEM upper coolant hose carefully. Then, install the new aluminum pipe from Wherli Fabrications in its place. Make sure to tighten the upgraded silicone boots and clamps properly. When it comes to maintenance, regularly check the clamps for tightness and the pipe for any signs of damage. If you notice any leaks or cracks, contact customer service. Also, remember that each pipe is made to order, so it may take a few weeks to arrive. And be aware that aftermarket radiators could cause fitment issues, so if you have one, double - check the fit before installation.
