Last year my AC went out. Charged it with freon and it worked for a couple weeks. Charged again and worked for a while, then petered out. Noticed tell-tale wet area at Condenser weld, passenger side.

 

Bought a brand new AC Delco condenser recently and installed it this past Saturday. Charged with freon but getting no cold at all. Any ideas off the cuff? Common problems with these? Things that are easily overlooked? Something special to double check?

 

Any suggestions would be appreciated.  Please and thank you.

Go to a shop and have the freon evacuated and new freon put in.
One cannot just top off an empty system without professional tools.
Also, make sure you installed the transmission line into the condenser, properly else you'll see transmission fluid everywhere.

Air can not be present in the AC system, otherwise it will not work. Thus the need for the machine or a vacuum pump on your own set of gauges.

Yeah, you can add freon to a system that's just a little low, but once you break it open you have to have a vacuum pulled on it before adding anymore.  You can't add to one that has atmospheric pressure inside already, you'll never get enough in there to work.  Plus, the moisture is terrible for the system.  

 

Get it evacuated and then charged.   Typically the books will tell you to pull a vacuum on it and hold it there for 30 minutes before charging.  Don't know if that's the case with these in particular or not.. 

 

I did have the condenser on my 15 Sierra fail a couple years ago.  Bought a new one from Autozone, replaced it in about an hour, took it down to one of my dealerships I do work for and had one of the guys evacuate/charge it.  Been perfect ever since. 

Good luck!

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
