I used a ball valve from hardware store because I was working out in the middle of nowhere and the only thing around was a hardware store I cut into the water pump hose and installed a ball valve with 2 barbed female male brass fittings along with hose clamps. It's been on there 3 yrs. With no problems, when winter gets here I just raise the hood and turn valve back on,I also leave it barely flowing just to keep coolant flowing through heater core. My AC is so cold in my 04 6.0 PowerStroke that I can't leave it on full blast on a 100°degree day or it will cause a brain and face freeze!!

There is an empty rubber stopper through the bulkhead right next to the under dash vacuum tube that was way easier to get through than next to the heater hoses and don't have to reach up behind the dash. It is behind the passenger wheel well plastic though. Other than that everything else is the same.

Does it matter if you put the hose from the water pump on the right or left inlet? Reason I ask is when I switch from max the valve doesn't revert to flow into heater core. I have verified with vacuum gauge that vacuum goes from 14 to 0 when switch is not on max.

Trey, what actuates the vacuum? Is there an on/off switch?
@FrGeorge
@FrGeorge 8 лет назад
cloudisunset - it's the same vacuum signal that closes the fresh-air door to recirculate air in the cab. Whenever you put the selector knob to Max A/C it closes the fresh-air door and actuates the bypass valve at the same time.
@cloudisunset
@cloudisunset 8 лет назад
George McGavern ahh, I want to have that thing shut most of the time. Maybe I can add a switch. Don't like the exhaust smell making it back into the cab.
@FrGeorge
@FrGeorge 8 лет назад
I ride around in Max A/C most of the time. In that mode, the heater core is bypassed. Occasionally when I'm not in traffic I switch over to norm just to make sure fresh fluid is flushed through the core. I don't know if it's that critical, I just feel like it's a good thing to do. Later trucks have this mod standard.
@jimgafford611
@jimgafford611 7 лет назад
George McGavern+ I have a 2004 f350 that when the Max A/C is on it will stop blowing out of the vents and start blowing out from the defrost vent. Is this normal because it seems cooler when I run it on just A/C.
@FrGeorge
@FrGeorge 7 лет назад
No. Sounds like you have an issue in your vacuum system. Could possibly be the line controlling the outside air door is off or broken causing the system vacuum to reduce, or it has been mis-plumbed. Vacuum controls the dampers that direct air to the vents, defrost, floor, etc. and it also controls the dampers that direct air from outside or recirculate it, and how much air passes over the heater core.

@maxwelljrdn
@maxwelljrdn 10 лет назад
Keeps the heat from the core from warming the air before it blows over the a/c evaporator. pretty much anytime the climate controls are "on" (heat or air), this valve is open, allowing water to flow. this is why if you select hot air on the blend even with the a/c on, you get full 150' air coming out cause there is water going thru. I think the tee he put in would seem to only apply vaccum to the valve and open when the heater only is on (floor or defrost). But the overall (and valid) theory is to keep all the extra heat out of the heater & a/c box. I did this in my Dodge van several years ago and my a/c got at least 15 degrees cooler, except instead of a stock valve I used two brass plumbing ball valves and capped the vaccum hose. I just open the hood and turn them on when it gets cold out.
