Anyone know how many 12oz cans of r-12 a 88 4runner, 22re (Nippondenso 10p15c compressor) would take? The system is completely empty.

 

there should be a charge sticker on the core support somewhere that will say

 

you need t ofix the leak or find out why it is completely empty.... also you will need to use the oil as well

 

jimabena74: it's empty beacuse the last owner put isopropane in it and because the compressor wore out and I didn't want the propane in there anymore, for saftey reasons. also I don't think it has any leaks but I need to fill it first.
superjoe83: I'll look for that tomorrow, but I don't think there is anything like that on the support. also I looked at the stickers under the hood and in the door and I couldn't find anything about the freon capacity.

 

i dont think you should use r12, i dotn think you can actually even buy it anymore... might want to look into r134a as refrigerant... any system designed for r12 can use r134a

 

Little cans of R12 are not avail anymore. 134a is the only substitute to put in there.

 

I already looked into converting ti to r-134a but I dont have the money to do that, plus I already have some old cans of r-12 and im in tucson so I can always go to mexico and get more if I need it.

 

bump, anyone know the freon capacity, in pounds or cans of freon. or where I can find it (my haynes manual dosn't say and I can't anything under the hood or compressor mount)

 

Please tell me you are MACS certified. If not then take it to a certified technician and delete this thread. If you are caught then *last time I checked* the fine is a minimum of $20,000 minimum.

 

I think the fine is $10,000 for an individual, but I can't be certain. It's definately not something you want to be caught doing. And yes, you need a license to handle the freon, any freon for that matter.

R-12 is still available, but very expensive... I think my shop charges close to $60 a pound. Whereas R-134A costs $13 a pound. The difference in cost will most likely offset any cost of conversion you need to make (at least in the long run). I'd suggest converting to R-134 and be kinder to the environment and also bring your vehicle up to date. My 2 cents.

Yeah our shop charges $50 a pound. I think you are right about the fine, but I may have gotten the $20,000 for the shop that is in violation? I'm pretty much covered since I have my license and evacuate all known leaks before service.

 

I'm not certified but my friend who is going to be evacuating and filling the system is.

 

Ok well according to Alldata it is 20.8-27.2 oz. with 5.5-7.5 oz of refrigerant oil.

 

you can buy a r134a retro fit kit at most auto parts stores. I did it to my 90 after fixing the hole in the pressure side works good now

 

Ironmike4x4: thanks for the help.
DudeBud: I'll look into it, but from what I've heard those kits don't work very well and inorder to do it right you need to flush your entire system and replace all of you o-rings, and somtimes replace hoses.

 

I'm glad SOMEBODY knows that!! (sorry, personal pet peeve of mine)
