Freon is very expensive if you can even find it. I recommend you have the system converted over to R134a refrigerant. The leak must be repaired before you can recharge the system. So you need to seek professional help to repair the leak and convert the system to R134a.
Was built for R12, should be converted to R134a
No, unless the a/c has been converted to r134a
When retrofitting a system with R134a refrigerant that was originally R12, it usually takes just a little less R134a than the original R12 did. Look for the sticker in the engine compartment or consult the owners manual for the original amount of R12 the system took. Then recharge with a few ounces less of the R134a. Also monitor the pressures during the process for reference.
If you are asking what type of freon to use then use R134a freon but if the vehicle has never had an a/c system then check a place called ackits.com and see if they would have an aftermarket system for this vehicle...........
A 85 model will have r-12 type refigerant, unfortanatly even if you find the freon finding hoses to charge the system can be costly and you would have to buy additional adapters if you ever tried to charge a r-134a system. The best recomendation I can give you is to convert your r-12 system to a r134a sytem. The parts are readily available and with the cost of r134-a being much cheaper it will probably cost about the same. Note this however! DO NOT put the same amount of r134a in the system as you would r-12! it should only hold about 85% as much to acheive the same pressure. Most r134a converion kits come with a gauge so you put in the right amount. Good luck with your A/C.........Im doing mine today as well
r134a you can get it at kregan or pepboy etc...i would get it done at a shop because if you overcharg(put too much in) it will rob extra horse power because the engine will have to put out more energy to pump the freon through the system
There is a label under the hood that tells the proper charge. It is an EXACT amount. That means exactly what it says. To much or to little will create problems. If it is low you need to have a qualified person charge the system and add a dye. This will make it possible to find the leak.
