Replacement SPL/SRL Heater Valve To Heater Core Hose

 

The short curved hose that connects the heater valve to the heater core may be replaced using a Gates 18821 pre-formed hose.  It does require cutting some of the hose off on either side of the preformed bends, but the bend shape is almost exactly the same as the Nissan supplied hose.  The inside diameter of the Gates hose is a snug, but nice, fit to the brass hose fittings on the heater valve and the heater core.  Once installed the hose appears to have been made for this application.
