AC not as cold as my 20 yo van....do I need the Muzzy AC hack

I put one of those on my truck and it lowered the temperature at my vent by 10 degrees.
 
I’ll never understand how my 20 year old half ton blows so much cooler than my brand new Laramie.

Ram climate control leaves a lot to be desired.
 
I think it’s been figured that the hack will deny coolant to the oil cooler, concerning the gas motors.
 
I live toward Naches ... Where I off road my RedX all year... 35s double locked

... So these rigs plumb the trans oil through the main radiator as opposed to having their own cooler? I will look into this... Thanks for the insight... I may have to order a separate trans cooler anyway if that's the case...

The engine oil cooler….If I remember right, it’s downstream of the heater core.
My truck has a trans cooler already.

I have been looking for a diagram of what you mentioned... Haven't found it yet... Traditionally the trans fluid runs directly to the bottom of the radiator and back to the trans.... Apparently there is a transmission thermal bypass for times when the transmission is getting warmer than normal like during heated climbs and towing... Then fluid goes to an auxiliary cooler...I don't see where the change in flow of radiator fluid from the heater core affects this process...if you have any more insight on this I would love to know as I don't want to accidentally do a mod that is self harming...

The engine oil cooler, if you block flow to the heater core you block flow to the engine oil cooler..I think.
Why I didn’t do the mod, it’s hot here and the AC is OK enough.

Right... I am seeing this now....I don't want my engine oil getting warmer... Kryptonite!

Yes, you will definitely block the flow to the oil cooler on the gas engines. One would have to plumb in a heater core bypass instead.
 
Southern Arizona here - been averaging 105+ - AC blows 34 degrees out of the vents - no hack needed.
