Reply to "Heater Hose Engine Routing Question"

bosswrenchMember

I believe you can rout them whatever way works for you. I also believe that you should add a manual shut-off valv somewhere in each of the the two hoses. The valves will be used to positively shut off water flow to the heater core in the summer; the stock in-dash heater control will not, due to a conflict between the undere-dash valve and the leverage of the stoch cable control. Most of us use brass ball valves with 1/4-turn levers that are reachable from outside the car, and these are required for open track events, for safety. They also markedly improve the performance of the stock air conditioning. 90 degree bends make it easier to clear the engine harmonic balencer.
