Little Hot, Sweating my @#$% off!
It's starting to get warm up in my part of the world and now I wish that I wouldnt have put a new blower and heater core in this winter. What can I do so that my truck doesnt allways blow hot air. It seems like whatever way I put the knobs on my non-ac truck it still blows hot, really hot air. Could I just take out a fuse or something, or disconect the lines that go to the air duct under the dash?

you could put a shut off valve inline in the hot coolant supply line.
I've seen plenty of guys just use a regular old garden hose tap.

But wont that cut off the coolant flow? Maybe I'm just not understanding something here. Does anyone have a picture of the valve setup? I'd really appreciate the help.

You could also re route your heater core hoses. run one from the two points on the engine that the hoses are currently connected to. then run the other hose from one end of the heater core to another. The valve is a better idea though, that way when it gets cool or your windows start to fog up you can just turn the valve open and go. The valve is supposed to cut off hot coolant from flowing into the heater core. It will not have a negitive effect on cooling. I do not have any pics though.

A/C trucks came from the factory with a vacuum operated cutoff valve.

If you have a NAPA in your area, they should have valves that you can put in the heater hoses and stop coolant flow into the heater core.
I had to do this on my 78 vette to prevent the hot air flow in the summer.

Initially, I installed a new Heater Control Valve. Didn't help. So, I installed a ball valve in mine. No more hot air and, the a/c blows about 10° colder, too!
Good Luck! TP |

Hey, 1sttimepro71, how hot does it get in Minnesota?
If you desire the best heat our great county has to offer, come on down to MS in July or August, temp may only reach 95-98 degrees Farienheit. The humidity is the killer running from 75% well into the 90% numbers, very hot sweltering heat. Stand still and just sweat, sweat, sweat.

We had a couple of days last summer where the heat index was 110. Thats about the extreme. But the opposite of that extreme is easily -60 with windchill.
CPNE I'll try what you said, thanks for the reply's guys.

couldn't you just loop a hose from your water pump to the intake? that is only if yours is set up like this. Mine is on my 350 but that engine is from an 82 with a long water pump.
