Does water flow through the heater all the time or is there an on/off valve?
I ask because I don't have a heater, the outlet from the back of the manifold is connected to the metal return pipe with a U shaped hose so I think the heater return is feeding water at engine temperature back into the front of the block via the pump all the time so am wondering if this is why the electric fans are on more than I would expect?
(I'm not overheating but the 2 speed electric fans do seem to be running nearly all the time on slow speed)
