93 XJ Sport 290k. Runs great.

Found out the A/C suction hose had rubbed through on the engine compartment fuse box (and that's why why my A/C performace degraded to nothing over the last couple of years).

I can get the hose at RockAuto for $36, but has anyone ever heard of or used this stuff?:




Says its an R12 equivalent. If it will work, will 2 cans fill an empty system?

 

I have never heard of that stuff so I can't comment on that. But just remember when you change out the hose you are going to have to pull a vacuum on the system before you add any freon. So, if you don't have a good AC vacuum pump you will have to take it in and have the system evacuated and see what they will also charge to refill the system.

 

Didn't know that RT - thanks.

 

Yes, pull a vacuum, and since it sounds like the system has been open to air, I'd change the dryer.

 

Unfortunately not a lot of people know that once the system is opened up to the atmosphere that you have to put a vacuum on the system to get all of the air and moisture system. The only reason I know is when I got my first car many many years ago. I replaced my entire ac system and didn't pull a vacuum on it and about 2 weeks later I had to replace the compressor. The more people that knows this the better. Good luck on you repairs and let us know how it comes out.

 

It's a hydrocarbon based refrigerant, same as DuraKool and the like. Propane and Butane.
It works pretty well provided: 1) it's legal in your state and 2) you don't mind flammable refrigerants.

 

I learned the same way. The moisture in the system will freeze into solid chunks. You compressor does not like solid chunks.
