DP Customs -10AN L5P Duramax Coolant Heater Hose Kit

The DP Customs -10 AN L5P Duramax Coolant Heater Hose Kit is a preassembled high end AN hose kit designed to replace your existing aftermarket rubber hoses found on competition L5P Duramax set ups. These kits utilize our Billet -10 AN Adapter Fittings which give you leak free and easy connections at the firewall and thermostat housing. Simply connect the barb Push-Lock fitting end to the lower 5/8 return hose (located by the belt tensioner) and secure it with the supplied Otiker clamp for a permanent tight connection on the other end. These line kits are perfect for competition set up use where clearance and heat resistance is key.
