Heater Hose Shutoff

[bobs66440]

There is a lot of heat coming into the passenger compartment via the heater hoses/heater core even though I don't have the heat on. I would like to put an inline shutoff valve in one of the hoses. Does it matter which one? (the one closer to the rad or the one closer to the back of the engine)

On a 440 the rear nipple on the water pump housing is hot water out, this is where you'd want to place a shutoff valve.

NAPA has the inline valve pictured below.

John,

Ive been looking for a simple valve like that for the time being. Do you have a PN or can i just ask for some universal heater valve? 

Thanks

I would imagine that almost any metal valve designed for liquid that fits the heater hose would work.


This one looks similar

Have you check if your coolant has a leak in it? The common defect a heater hose is its leak. Better check it first.

I had a valve like that on my 69 corvette. Worked great, make sure you put it on the heater core outlet side.

I know this is an old topic but I picked one of these valves up yesterday and want to be sure where to install. So off of the heater core in/out which(right or left side when looking at the firewall) do I install? thx guys

Couldn't shutting down the heater core cause back pressure and cause flow problems?

Nope, thats how the factory did it.

Check the second or so post "rear nipple on the wp housing"
