Heater Shutoff Valve?
Greetings,
I'm looking for a part number for adding a 4 port vacuum controlled shutoff valve in the coolant lines feeding the heater. Preferably, I could pick one up at my local NAPA. I could have sworn I had seen such a post in this forum, but I can't find it.
A few years ago, I added a 2 port shutoff valve (NAPA #660-1200) and it worked great, but it completely shuts off coolant flow in the heater circuit. I now realize a 4 port version would be better, as it would return the coolant instead of completely stopping the flow.
I'm looking for a valve that diverts the flow when vacuum is applied, and runs straight through when vacuum is released.
Thanks

Thanks! That translates to BK 6601294 at NAPA, for anybody else in search of this valve.

I tried a 4 port for awhile, it ended up leaking coolant out the vacuum line. So I switched to a 2 port and have noticed any issues yet. Also keep in mind the 2 port was available on the vans, so I figured it was capable of the same duty as the trucks.
