Using this coolant hose reroute kit is easy. First, make sure your engine is cool. Then, carefully remove the old factory heater coolant inlet tube and degas return hoses. Take the parts from the kit, like the billet aluminum heater inlet adapter, and connect the 5 - ply polyester reinforced silicone hoses using the 90° quick - connect hose ends and hose clamps. Follow the plug - and - play design and you don't need to cut or change the factory lines. When installing, be gentle with the parts to avoid damage. Check all connections are tight to prevent leaks. For maintenance, regularly inspect the hoses for any signs of wear, like cracks or bulges. If you notice any issues, replace the hoses right away. Also, keep the anodized billet aluminum heater inlet fitting clean. This will help the kit last a long time and keep your engine running smoothly.
