Prelude heater bypass, how to...
Over on the Prelude group, I'm working out issues on my mid-engine Mini. https://honda-tech.com/zerothread?id=1283595
I know you guys must have run into this same thing. Long story short, I put the engine behind the seats and am not using the factory heater or it's hoses. What's the right way to deal with the hoses, connect them together, allowing the coolant to go on it's way, or plug both? My thinking was since there must be a valve in the heater turning on and off the flow, blocking the hoses should be fine, but now I'm not so sure. Since I'm having cooling system issues now I'm reexamining how I did everything. Specifically, my dash ECT gauge reads 210deg F at the same time the ECT sensor feeding the ECU is telling it the engine is 140deg F. Not good since it's preventing VTEC goodness from happening.
