Adding A/C Coolant

[JBronco]

Hello,

I have a 88 Bronco 351w and my A/C needs recharged and im not sure where the low pressure connection is to add the coolant. I see there is a connection next to the accumulator but not sure if that is the one i should use. Last year I added coolant and had the AC working good i used 134a coolant and it worked great, trouble is i forgot where i added the coolalant. Can someone please help me with some Info

Thanks

A/C units are more of a specialty thing, I don't like to fool around with them. I think the 88 used R12, my 90 uses R12. Would call a repair shop with that question. Also it is good practice to perotically check the A/C, even during the winter, turn it on, get the coolant moving, this will be early detection for any problems during the summer whe you'll need it.

Gotta agree with Fire here...AC is not something you want to fool around with if you don't have the proper gauges and don't know how to read the high and low side pressure. 134A refrigerant will work fine in old systems with the proper fittings placed on the upper and lower side....but you have to evacuate the R12 from the system completly to do it. This requires a special box that has an air fitting. Go have it evacuated, charged and oiled. Have them check for leaks. It's worth the money.

You also need a special licence to evacuate R12.

yea cuz r12 is so bad and 134a is so much better...yea right its just as bad but yea you can get a conversion done

 

[firelt90bronco]

The conversion kit will cost some $$$$ though.

I suppose you are looking at one of those DO IT YOURSELF kits in the parts store. They are 134a. Don't mix it with the R12 in your system. You need to have it pumped down before putting in R134a.

Good luck,

Umm, that's what I said Seabronc. /emoticons/[email protected] 2x" width="20" height="20" />

I don't know about where you live...but here, no license is required to do the evacuation on your own. You can go to the nearest Snap-On man and buy the evacuater. And you don't have to change the whole system. It only requires different fitting on the valves on the upper and lower side. Those guys at the repair garages will tell you that you have to change everything out. That's total BS. An AC system from days of old will work just fine with 134A...but you MUST evacuate ALL the R12 OUT.

A kit can be bought at Oreilly's or Wal-Mart or any other automotive parts dealer. Less than $100 for the whole thing...including new 134A and oil charge.

Good Luck!

OH yah, so you did! Well, now he has heard it 3 times /emoticons/[email protected] 2x" width="20" height="20" /> . Hope he gets the point /emoticons/[email protected] 2x" width="20" height="20" /> Oh yah, here you have to be state certified to pump it out. You can add but the R12 "is supposed to be safely disposed of in a certified container. We just bought a complete service system at work, $800.00 for the purge system plus another $600 for vacuum pump, scale and storage tank, gauges.

Thank you seabronc, I almost got the permit to do it, but figured it would be too much hassle.

Sorry if that came across wrong Fred, I wasn't trying to be a smarta**. Wow, $1400 for the equipment just to evacuate it? And a license? Maybe I better check my local laws again. It doesn't matter now really...I've already evacuated my system and put in 134. But, it has a leak. I guess I need a new compressor and lines. The leak sounds like it is coming from the compressor. Where can a guy find a good deal on an AC compressor?

This is my two cents from a Florida Native Born and Breed. Find a good shop take it there and ask for just the recharge. You may have to argue alttle with them but don't take their crap. My wife's Jeep's A/C compressor went out last year and I found another one "Used" and installed it myself. I drove to a well known and respected shop in Deland and just got the charge/Vac. and it still works great ice cold. They told me up front that I needed to replace a whole list of parts that where still working fine just because the compressor went out and may have affected the whole system. Bull@&%$!!!! The recharge/Vac may cost $29.00 to $70.00 it's up to the shop. One of my dispatchers had his system charged for less then $40.00. It's worth the money to let a shop charge the system. I tried the kits and all I did was throw money away. You have to have the Charge&Vac. not just a kit you pick up at AutoZone that charges the system. Well thats more then two cents worth.

ive got the vaceum pump ac charge and three canisters of r12the stuff is no longer in manufacturing phase and is around $1000 per 30pound tank im not certified to do anything with these refrigerant tools and am loking to sell them
