Hi all,
This is a follow on to my heater problems. After replacing the mono valve kit (No torn rubber) and the thermostat, disconnecting the aux coolant pump and numerous R&Rs of associated components I am at the point that I have good heat up to the magic number 2000 RPM beyond which I lose heat. Its cold here and I am actively pissing off a lot of folks by driving keeping the RPM just below 2000 which by the way does not correspond to much speed. I have read many threads on the subject, but have not determined if anyone has figured out what is the culprit or at least a logical technical explanation of what is happening. Does paying $250+ for new complete mono valve, solenoid and all solve the problem or its the dash controller????
