I just bought a can of "Glacier Ice auto air conditioning R-134A refrigerant+"(with oil and leak sealer) and am now thinking twice about recharging my own system using this product. WHY? Well, I figure that with Land Rover pretty much everything is Land Rover specific and I am starting to have second thoughts! Anyone out there used this type of refrigerant or any other similar product and how did it work? This can comes with a guage to tell you when to stop adding the
refrigerant---thought that could be a plus!

Here is a picture of the exact can I bought-

How did you test your a/c to determine it needs freon, what is it doing??

I have not tested it yet, I only know that the air is not very cold anymore and figured that this was the cure. Am I wrong to assume this? Everything is in good operating condition so far. No crazy sounds coming from anywhere and the fan is blowing strong.

Check you A/C compressor first to see if it works when the A/C is on "on". If you're around the engine compartment when someone in the car turns on the A/C, you'll hear a "click" and will notice some noise from the compressore. Unfortunately because of a shroud, you won't see the A/C pulley turning. If are going to do this PLEASE make sure you don't have any loose clothing ( like a neck tie ) before you go snooping under the hood with a running engine.

JR,
You may be right, trouble is if you recharge it, it will leak down again at some point so this is a short term fix. I would use the freon that doesn't contain any sealer first and see how long it holds up. I am concerned about the sealer and if it will gum up the works. What ever you do, don't over charge the system.
Good luck,
Mike

 

Well, I checked the pressure and everything is good. I do not need to add any of this coolant and will be returning it to the store. I guess my next step is to check and if needed replace the compressor. Thanks again to all who have replied to this thred. --Good luck and many thanks---JR

 

Jr,
What exactly is your complaint with the a/c?
There is a self test you can run on the a/c in your truck, send me your e-mail address and I will send you a copy of it.

Yeah don't ever use any of that freon with "magic sealer" in it. It will just cause more problems later on, it's only a temporary fix. I've not been on the A/Cforum in a long time but it was very helpful the last time I used it. Maybe they can give you some direction in your A/C issues?http://acsource.net/acforum/

 

I used leak sealer in my 1999 Mercury 3 years ago. It works great. Haven't had a problem since.

On the other hand, my Disco leaks down over 24 hours, and sealer won't help that.

 

Must be put on LOW side with blue cap. Or the can could explode and harm you.

Engine must be running
A/C on LOW

Get a meat thermometer.
Put it in the vents.

Put in A LITTLE. Just a little.
See if the temp goes DOWN.

Then a little more.

You will see

temp
down
down
down
no change
up

at no change -- stop.
You added enough.

If too much, compressor goes on and off fast.
