Year: 1987
Make: bmw
Model: 325
Engine Size: i6
Refrigerant Type: r12
Country of Origin: United States

Hello

I have a 1987 bmw R12 and the ac does not work. Im mechanically inclined but when it comes to the ac system im not
i think i can get it done with a little help

i also would like to learn and have the tools to be able to fix friends cars or maybe even really get into it and get good at it but for now my concern is getting my ac fixed

i figure im going to need gauges, vacuum pump, and other misc. and i will want to replace my ac dryer and orfice tube and all the O rings and seals???

im also a little lost about what exactly i will need to do like what are the steps i will go through when charging the ac system
i plan on buying this r12 called freeze r12 its a substitute for r12 unless anyone has something else

do i have to add oil to the system or is that only if the compressor is low on oil and how do you check the oil level in the compressor

First Step I would suggest is picking up Mastercool's Repair Manual. It just covers the basics but is an excellent source for repairing an auto a/c system.

Second I would stay with R12 over an alternative refrigerant!!!!! Fix the problem and have the best working system you can R12 is available and will be for a long time. Individuals can purchase it by becoming certified. $ 25.00 dollar on-line test which is open book.

thanks for the help
i ordered the book

just a quick question on my mind

the ac system doesnt work i beleive it had a leak. I just went outside and spun the compresssor and it felt really free i spun the clutch part not just the pully. so i beleive the compressor shall work just fine.

this car is 20years old so far i plan on replacing the expansion valve and dryer and all O rings

i noticed on the compressor itself there was a flat connection which looked like a gasket type surface
should i replace that while im at it

i also noticed some of the ac lines(mostly the ones that look like flexible rubber hose, where theres metal connections on them it looks pitted and rusty on the surface area) should that be ok because new lines were expensive online.

another how am i to know how much oil is in the system whats the best way to go about all this
thanks ryan

As far as the guages, vacuum pump etc, check out Mastercoom DIY'er kits as it has all you'll need to do the job.. Is there any refrigerant in the system? when was the last time it worked??

theres no refrigerant in the system it worked slightly when i bought the car about 5 years ago when i bought it the lady said if you charge it it would last the whole summer but not the next

Find the leak first. Go from there as to what needs replacing. Hoses can be redone with new rubber, reusing the expensive metal ends.

i plan on replaceing all the o rings and pulling a vacuum to see if it will hold

should i replace the dryer after i know it holds a vacuum?????

Changing the drier is the cheapest insurance you can buy for your system. It not only absorbs moisture (and your system has been empty to long) but has a filter in it.. If you can't find it on Ackits.com, e-mail them at ackits e-mail and have them look it up, I can't open their website right now.. But if it were mine, I'd change it... You can even change it, charge it, find the leak, fix it, and reuse the new drier since it won''t be open that long... Do it right and you'll do it once...Hope this helps..

You don't have to take my advice, use your old drier, but you will change it later, along with a lot of other things..I highly recommend Ackits.com for their fast service, standing behind their products and and the quality of them. Best store on the internet. You wouldn't know it until you have a problem, then you'll find out... No, I live in New Jersey, no where near the Hellish heat of AZ...
