You can also put your vacuum controlled shut off valve on a switch to operate from the cab. I personally like this option the best.

Edit: Correction: I should have said tee-ing into the RED vac line.

Here in Payson, AZ (5,000 Ft) it is either Hot or Cold. When it starts cooling off I remove and plug the vac line at the valve so there is heat coming out the dash vents. That is the drawback to tee-ing into the white vac line, no heat in highlighted switch positions because the valve is in the divert position. Think about that before choosing either the white or red vac like to tee into.

Heat to floor and defrost will work but not dash vents or dash vents/floor vents. Diverter valve operates in thiose positions.

you cut both lines and install it. then you run a vacuum line to under the dash and T-in.
had a manual, then installed the old version of this one:

and the ranger valve by far out performs them all.
NOte: getting under the hood to turn the valve on and off SUCKS. The ~$20 is well worth it.

Besides if you used a diverter valve it should not build pressure, but divert the coolant back toward the water pump.
The diverter valve also needs to be oriented properly so the coolant pressure is not working against the operation the diverter. The valve I installed had coolant flow direction arrows.
The valve should be non-operated in the off position.

Autozone, but of course, had to buy the pack with 10 other T's in it, for 5 buks. Probably Ace also, individually

Meant to ask, why is that? And don't mean to question but it is more that i want to learn something. Coolant gets old and causes you to need a new heater core? I had a car in the barn 15 years, no circulation, Pulled it out, New gas and drove it for two years. No heater core failure. Maybe i just got lucky?
I love the pic hilighting which switch positions are affected, that's hard to describe in words. This was the first mod I did on my truck. I used Neal's writeup and I'm going to check out the link above too. One tip I coulda used: the Dinky vacuum lines had me confused until I realized ya don't stick the fitting into the hose like the old style big hoses, instead the hose and tee go into a short bit of connector hose.

Aren't the radiators inside the core assembly aluminum?
Another question. If i take off the degas bottle cap, What would the flow pressure be from the head output to the heater core inlet? Thinking about this option, Instead of a manual valve, Install this, Then hook it to one of the empty push buttons on my dash. Trying to figure out what the flow pressure is because of valve is only 1/2" npt. 1lb-5lb?

Thanks Tim, I lost that website, and could not find it. Thanks for bringing it back to me.
That one was 1/4" NPT. 2.7 orifice
1/2" NPT was 16mm orifice

1" is 25mm orifice.. IDEAL .635" ID
Bit pricey, Hummm.. O well, It was a thought.
