Looking to fix your leaking heater hoses? Full Send Diesel has the solution. Our bottom heater hose replacement is made from the best -10AN braided hose and fittings. It is designed to replace the bottom heater hose that runs to the front of the engine to the heater core connection on the firewall. If you have a manual transmission this is a direct replacement, if you have an automatic transmission this will bypass the heat exchanger mounted on the side of the block. This can be routed a few different ways although we prefer to route it underneath the manifold.
- Lifetime Warranty
- Billet AN Fittings
- Durable Braided Hose
