Z71 Tahoe Enjoyer
With the recent heat wave, the AC once again leaves a lot to desired once idling in the torturous midday sun.
Had my AC guy check the refrigerant, pressures, airflow, etc. All was good. The AC is great if it’s below 90 outside. Once it gets over 90 it starts struggling at idle.
I can elevate the rpm’s slightly and can immediately tell a difference. More air is pulling through the condenser, but also the compressor is spinning faster obviously. Which of the two makes the bigger difference?
It crossed my mind that I could install a smaller pulley on the AC compressor to make it spin a little faster at idle, has anyone done this with noticeable results?
Also all I’ve seen is underdrive crank pulleys. Do they make an overdrive one?
Just some ideas I’m tossing around. Maybe the heat is taking it’s toll on me.
I should also mention that I use a severe duty clutch with the 9(?) blade plastic fan, it engages constantly and stays locked in. Also have the factory auxiliary electric fan, it stays on with a manual switch.
