Default removing a/c

Does not running a/c give the car better cooling as the condenser is no longer interfering with airflow to the radiator? And would having an IC and a/c make a car much more likely to overheat as there is a lot of metal in the airflow of the rad?

I'm asking because a stupid deer made me hit a storm drain cover, and ruin my a/c condenser. And now I am debating weather of not to get rid of my a/c system and just deal with it, or try and fix it.

You don't need no stinking A/C in California. Why would you ever drive with the top up? Get rid of it.. makes routing your IC pipes A LOT EASIER!

There aren't any removal instructions that I know of, but there are install instructions that you can work backwards from.

First thing is to have it professionally drained. There's probably a shop in your area that will do it for like $20. DON'T GO TO PEP BOYS or a name brand place. Take it to Jose's Radiator and AC Shop or something like that and just say you want it drained. Freon or R-134 whatever is nasty stuff... don't **** with it yourself.

Past that, just start unbolting. You'll need a replacement PS belt if you've got that system. It's pretty easy. There are a bunch of hoses that go from the compressor/condensor/evaporator. Remove them, then unbolt the compressor motor and condensor. If you decide to remove the evaporator in the passenger footwell, you'll need the crossover tube to insert in it's place. They're like $35 from a dealership... or you can leave it in and just cap the tubes sticking through the firewall (use duct tape).

Seriously, it's EASY. Just unbolt everything and take it out.

I THINK... I have already accidentally drained the system when I smashed the condenser into the storm drain cover.

Thanks for the info, I'll get to unbolting stuff as soon as possible.

Nope, there'll still be some in the evaporator and residual in the lines. They put some vaccum line sucking thing in it and REALLY get it all out. That stuff is nasty, take it to a pro just to be sure.

uhh.. if you drive to San Bernardino, the temps easily get into the 90s. Or you could be sitting in a black car, in traffic, in a SUIT/tie/jacket, trying to go to lunch, and being roasted alive... say.. like.. TODAY.

speedf50 (i think i PM'd you on Miata.net last week about your tsudo?), the condenser can be had for < $50 from all the local junkers. as long as the junked car hasn't been sitting outside for too long, a salvaged condenser will work just as well. it's totally easy to uninstall/install (4 bolts, 10mm head & 2 crescent wrenches to undo the A/C hard lines.

then you can just go get your r12 recharged by a local A/C shop. total repair bill shouldn't be more than $200. not having operating A/C also significantly detracts your car's resale value.

Where does the price jump from $70 ($50 condenser and $20 to drain system) to $200?? If it's going to cost me that much to get it refilled, then I will just go without a/c. I am on a really tight budget, and even though I do drive a black car... I need tires right now.

Oh and ya, you get the tsudo?

r12 costs beauceau dollars. 2 cans of r134a + 1 can of oil runs... $20... filling r12... costs something like $100. of course you can call around, etc.

there's no need to remove it even if you can't fix it right away. the busted condenser isn't hurting you car. you should've TOLD me about your busted condenser. I had one (from a '96) in my hand last week @ Ecology junkyard (Santa Fe Spring). Would've only cost you $33.

as far as tires vs. a/c vs. everything. let's put it this way.. you bought a $250 catback. but you can't afford tires? nono: my falken 912s cost me $200 mounted out the door. Chinky hookup in Monterey Park. :gay:

But to replace the condenser, I have to drain/refill the system anyways right? So basically to have a/c will cost me a lot.

And a few weeks ago I could have gotten my a/c fixed and tires, but after ordering my voodoo II system and accompanying parts, I'm quite broke. Think your chinky hookup can get me RT-615's?

Chinky Hookup offered me 15" RT-615s for $340 installed. no tax...

if your a/c system is completely drained due to busted condenser, i'd just go fill that baby up w/ r134a for $20. that'll put the cost of fixing a/c at.. $50 if you can find a condenser for CHEAP. and you can. it's LA. junker Miatas everywhere.

Wait, wasn't r12 only in the older miatas? Would my 97 be r134a? And do you think a shop would charge around $20 to just fill with r134? Or is that something that I can do myself because I would not be dealing with the r12. If thats the case then I already know of a place that has junker miatas, so I can get a condenser for cheap.

I just hope that my system is completely drained from smashing my condenser, as I preferably want to put the condenser in while my radiator is out (now) and save the hassle of re-draining/filling it just to drive it down to an a/c place.

Thanks for the help. And Tony, delete some of your pm's, your box is full and I have a chinky question.

Nope. If any part of the system was open to ambiant air it's empty. The high and low sides equalize via. the orifice before the evaporator so the entire system is empty. The only thing in there is oil. The reason they vac it down is to "boil off" any water or humidity in the system and remove all the air so there's nothing but freon (and oil) in there.

So... that something that I am going to want to have done right? From what I have heard the a/c system gets really easily damaged from humidity and that stuff.

But with that in mind, this means that I can first switch out my condenser as there is no pressure in the system now, and then take it to an a/c place to get the humidity and gunk out and put freon back in? If this is the case, then sweet ****! This will be a lot easier.

Correct. Water=bad. It causes corrosion inside the system. '97 is a 134 system. You don't HAVE to vacuum it down but it's recomended. I have a trick I use to purge -some- air out but I don't recomend it. lol I'm just a cheap bastard. :gay:

So, getting the system drained is about $20 right? And a refill in 134 is not that much either, and is the refill something that I can do with one of those cans? Or is it not much more at a shop?

thanks for all of the help
