Belts! & Water Pump

Well while sitting in a parking lot enjoying my new AC system that has my Hummer down to 67F in side and windows all fogging up on the outside, a belt broke. It was the alternator belts. No biggie, drive it back to the warehouse. Next morning I got new belts.

Two belts broke, both for the alternator. Found a second belt had jumps to the wrong pulley and was also twisted. Removed all the belts. Then found that the water pump is now very wobbly. I think one of the broken belts got under the other belts and caused the pump to break. So, I will have a shop fix it, I don't feel like messing with it right now, just too hot out!

You Know the A/C works when ......

Yes! Finally the A/C is in service and you know it is working when all the windows (except one) are all fogged up on the out side. Only the armored window was not fogged up. The A/C blows cold air even on a hot 90F day like to day while sitting idle. And on move it chills the vent air down to 43F before the compressor will shut off. It normally blowing between 43F and 48F.

Some time back in June , I got a new A/C compressor. Then finally in mid July I got it mounted. Then finally the first of month, August I took it to the A/C shop to have the connectors fitted and connected. Ran in to a problem, 2 problems, 1) I did not have the connectors for filling the system, and 2) the new inside A/C core had a hole in it. So Monday it was not completed due to lack of the fittings for filling. Tuesday it was not completed because of a hole in the coils we found when filling the system. Called up RedDot and they sent a new coil over night and so Wednesday it was finally completed.

I want to take it back because the connectors and hose are not in the right place and as a result, the side cover does not fit right and the hose is on a sharp edge under the hood. And I also have no low pressure switch in the system.

But other then a few minor issues, the system works great. The system sits between the rear sits, but the air flow you can feel up front with out any problems.

Setting the temperature is limited to 3 settings, you set the fan to low, medium, or high and once the coils get so cold, the compressor will shut off. So, so far I know the high speed setting is 67F before the A/C compressor shuts off with it being 90F outside. Also with the new fan on the outside, you can feel the air being sucked in under the hood scoop.

Now I have to make a few other changes in the wiring, since this system has two blower motors, it pulls more current then the older unit which had a single blower motor. Then I need to make a new cover for it to dress it up some. All in time.

A/C Shop: $450 for installing the fittings and charging the system.
