Question : If you have a leak at the heater control valve/hose connection point under the hood, would it be normal that this would leak when you have the heat on but not leak when you have it off ?
Background:
Due to a loose water pump belt I replace the belts and tensioned to spec (yes, using the right and expensive gauge). I drained all the stuff in the system and used a light (150/gal hour) pump to flush with distilled water. I then refilled everything with distilled water ONLY and burped it. Right now I am not putting coolant in as I want to find leaks now that the water pump is properly pushing liquid around.
There seems to be a slight leak around one of the oil cooler connections to pipes, but the bigger leak/spew is that at the heater control valve. I suspect I either leaked too much H20 to have it leak once I turned the heat off OR I don't understand enough about the system and it makes perfect sense that it wouldn't leak with the heater off. Which is it ?
