should I turn the valve off or could I disconnect the two hoses from the engine ( heater in and out I think )and join the outlet and inlet on the engine with a hose to complete the water circulation. your input would be well recieved.

You'll probably find the rubber stopper inside isn't moving quite as much as it should, allowing a small amount of water (air when blowing!) through.janstolp wrote: Is that done on purpose to keep some circulation i.e. better cooling near cil. four?
Or is this valve also at fault ,what would be pitty ofcourse.
