R134 condensor
Ready-Aire - Air Conditioning Condenser
Part Number: 636420  I bought a new condensor. Here are the pictures of it.  Yes, this condensor is a multiple path (cross) flow condensor designed for R134. Yes, the Orielly's computer lists it as a direct replacement. I guess manufacturers decided to make them for older trucks. Now, I just need time to discharge my current system to install it.

Re: R134 condensor
How well does your air work right now? I've been thinking about doing the same thing with my Burb. It works well except the really hot days, it's just so-so. It could stand to blow out the dash a little faster too.

Re: R134 condensor
Mine works great when the truck is moving. City driving and stop lights are bad. Install some foam pads between the radiator and condensor. Get as much air through the condensor as possible. You can even use padding over the top portion. I'm replacing mine since I run electric fans. My fans are not running all the time. The single tube R12 design can work if you run enough air through the condensor.
If anyone upgrades to R134, consider upgrading the condensor. $119.16 with tax at O'rielly's. |

Re: R134 condensor
Will that condensor help with non having cold air at idle. Mines nice and going down the road but when you stop it slowly gets warmer.

Re: R134 condensor
What about putting electric fans on there that should pull air through the condensor at idle right?

Re: R134 condensor
That is what a modern day car does. When the ac is turned on the fan comes on.

Re: R134 condensor
If it's not working well at idle, replace the fan clutch. If you have electric fans, they NEED to be on when the AC is on. Some fan controllers have an AC input wire so the fans automatically come on (it needs wired in, of course).

Re: R134 condensor
I wonder if the 73-80 condensers will be available in the newer design? I am sure the newer style condensor will make an incredible difference in the vent temps.

Re: R134 condensor
If you do get electric fan you will go on when your A/C is on so that should shove your problem with warm air at stop lights..

Re: R134 condensor
Yes, I was just pointing out that if the AC is turned on, there needs to be good air flow while stopped. It is very important that the electric fan comes on with the AC on. Without it, not only will the AC not blow cold, but it will build up excessive pressure and shorten the life of the compressor.

Re: R134 condensor
Fat hoe I was thinking the same thing reading through the thread I don't imagine it would be hard to install an electric fan and a switch under the dash. I'm going to have to remember this when I go after my ac replacement

Re: R134 condensor
It's 6mm. As far as I know they do not make a true parallel flow condenser for these trucks. Probably never will.

Re: R134 condensor
I agree. The new condensor is a little improvement over the R12 condensor.

Re: R134 condensor
It may be a few more weeks before I have a chance to install it. Either way, the condensor is an improvement. I recommend the upgrade for a R134 conversion.

Re: R134 condensor
I've had this type condenser in my truck over four years now. It's pretty much what you will get if you buy from any of the big part store. I've done all the tweaks you can think of, from sealing the gaps to the E fan etc. Every bit helps. It is better the the 3/8 tube condenser. The bad thing is the condenser in these trucks are small. If they were bigger it would really work good. You still should see an improvement if everything is done right. I still have the R4 which I hate. The only reason I didn't change to a Sanden & true parallel condenser is I want to keep the factory look. Except for the E fan of course.

Re: R134 condensor
i have the stock condensor and evap in the truck. orielly orfice tube and accumulator, stock 5.3 compressor and after i put the fan shroud on the truck the vent temps are at 50* after 5 mintues of driiving. charged the system to 1.85ish lbs and the pressures were at 28-35low and 200-220 on the high. good enough in my book. I had it at 1.75lbs but the compressor would cycle at idle.. added the extra .1 and it doesnt cycle as much and the high side pressures only went up like 5psi..
