OK, I just completed the job in 45 minutes and I stopped many times to show my wife how to do it.
1.) DO NOT waste your time (and fluid) removing the transmission lines. They simply pop out of the plastic clips on the shroud that hold them there (slide under the front to easily do this).
2.) The AC Delco fan clutch is $227 at Rock auto which is what the st(d)ealership would install (and charges $597). The AC Delco part is a Behr part which is made for AC Delco.
3.) The stealership charges 3 hours of labor to do the job where I, a novice did it in 45 minutes. All quotes from 3 different stealerships were over $800 ($300 labor + $600 part). Shame on them charging for 3 hours verses the 1 it really takes.
You have the right idea right there.I wonder if adding an electric fan wouldn't solve this problem cheaper than replacing the OEM fan. The OEM seems to be another GM engineering marvel. The kind that has put them out of business twice now and will continue to plague them until they disappear all together.
This actually happens because at idle or low speed you have limited airflow across the condenser. In high ambient temperatures you have the added problem of the condenser being in close proximity to the radiator. Since the condenser isn't reducing the coolant down the compressor is not as efficient in pumping the refrigerant through the evaporator.I'll be honest, I'm an A.C. whore. I HATE heat so I use the air conditioning more than anyone I've ever met.
From my experience, all cars I have ever owned or driven seem to cool the car better while driving than while stopped. Sometimes it's very noticable, sometimes it's not- but it's always there.
I've always assumed it does that because the engine isn't turning the compressor fast enough, similar to the way that the headlights in some cars will get brighter when you step on the gas because at idle the alternator isn't turning fast enough to be at it's maximum efficiency.
Sounds Like Low Freon ( sometimes compressed air can be mistakenly added , without the freon being added )Engine sounds fine, this only seems to happen when its really hot outside, if I stop at a light, or when I start the engine, even if its already up to operating temp.... Once I step on the gas, its gets cool. The dealer says they did a A/C and heating test on the truck and found no problems. I couldn't get it to do it at the dealer because it was early morning.
Not even a shred of reasonable advice there.Sounds Like Low Freon ( sometimes compressed air can be mistakenly added , without the freon being added )
Maybe lots of stored Dirt/Carbon/Mud under the vehicle? water from condensation can't drain?
Other things to keep in mind, is the Pully Wheel for the compressor , Maybe you have a Loose Belt that runs all those Pully wheels.
Belt be slipping? Especially when stepping on the gas. ( best to take belt off, and try to spin the pully wheels with your hand ) should spin easily, like a cheap walmart skateboard wheel lol.
The only other thing to check, would be your Thermostat...
Make sure you have the Proper Coolant/antifreeze.
If thermostat is stuck open.... your vehicle would kinda rarely hit the half way point on the temp gauge, and will always be between 140-180, instead of 210..
Will be 210, only if sitting at stop sign or drive through too long. But as soon as you hit the gas.... maybe 15 sec... then boom cold air.. then yeah it can definately be a
thermostat issue, or Mud under the vehicle.
Take it to the car wash, for an under-body spray cleaning.
