3rd Gen Tech: Colder AC in under 25
#12
Well I did the mod, and it turned out great. The only thing I did different was I found a 3/4" valve with 3/4" barbed ends (all one piece). I let the truck sit for awhile then went out there cut the hose, put on the hose clamps, and put the valve in. Worked like a charm. The valve cost me about $7.50 at Lowes. It took longer to wait for the truck to cool down enough than it did to put the valve in. I saw a 14* drop in temp coming out of the vent.
Thanks Wildcat

I too looked for an "All in one" valve. I couldn't find one with 5/8" barbed fittings. I figured if I was having trouble tracking down a 5/8" valve, or a 3/4 valve with 5/8" barbed fittings, others might also, so I would just cover the assembly of something that would work.
Did you have trouble getting the 5/8" hose over the 3/4" fittings?
Glad this helped you!

I "wonder" if it leaks by... Most of them do.. (By design, I think)

5,000 to 10,000 miles, about your typical diesel truck oil change.....on a newer truck i wouldnt worry, on something 10 years old i would worry more about it......and 14 degrees is a HUGE drop in air temp......what was the before and after temps and what was the outside air temp at the time you did the measuring.....

NP man.

No I didnt have any trouble getting the 3/4 onto the 5/8 hose, the motor and that hose was still pretty warm so the hose was pretty flexible and the barbs just kinda slipped right in.

Logan, I bought the temp gauge and put in the air vent on the drive home approx 20min, it never got below 55, I pulled in the garage and sat there about 10 min at idle still never went below 55, I did the mod went for a 20min drive and it got down to 41* sat in the garage for about 10min at idle and it stayed at 41 never went lower than that. The outside temp was hoovering around 100*.

A couple problems I saw right off were the hose you need to cut the valve into isn't as accessible as on the 5.9L. Also your turbo is water cooled, and that would need to be addressed.
So, you would probably need 2-3 valves, and a Tee or 2 to plumb in a bypass for the heater core.
I guess I should have looked at it closer, but then it was hot outside and the thought of cool beverage and fellow diesel enthusiasts were calling me in...
Maybe if someone wants me to do one here local, I can take another look at what it would take... They will have to buy everything tho'...
