Cost/Difficulty level of working on the AC in a 92 Prelude

Hey everyone.

Tonight I noticed my car knocking from what seems to be the AC compressor. sound only comes on when the AC comes on. Its not the fan, beacuse I unpluged the power to the fan temporarily so that it wouldn't spin to see if the noise would continue.

The car was updated to the new refridgerant in 97 by the previous owner.

Anyone know what it costs to look get this thing looked at? The compressor doesn't look like it too hard to get to from the bottom. but anyone have any experience with either compressors or work on their ACs?

on a side note, the car blows ice cold air....

any thoughts?

the whole recover refridgerant thing- hard to do. not the worst thing in the world to do.

Re: Cost/Difficulty level of working on the AC in a 92 Prelude

sounds like compressor clutch to me. i do a/c work on quite a few different cars and preludes are no where near the worst. updating from r12 to r134a will not cause it to knock. compressor work is not difficult. however it is important that there is no refrigerant or pressure in the lines before you open the system up for repairs. dont be a jackass and release it into the air. take it to a shop and pay to have it evacuated and any good shop will recharge it for free or charge you for whatever was missing.

Re: Cost/Difficulty level of working on the AC in a 92 Prelude

well its most likely book time which diag is generally an hour. if it is compressor it will probably be anywhere from 1.5 to 3 hours. i believe that includes recharge. if not then thats another hour. at the absolute max you are looking at 5 hours. i dont know what the labor rate is around your area but here it just went up to $99/ hour

go spend the money for diag. at least you know what it is. find out and get an estimate for repair. if too much then look at doing it yourself.

Re: Cost/Difficulty level of working on the AC in a 92 Prelude

I know I'm getting ahead of myself here, my first step like you suggest will be to get it diagnosed.

If I decide to do the work myself, I'll have a shop get the refridgerent out for me and probably try to use one of ther $160 A/C Compressors on Ebay....

If I decide to go that route, the only thing I'm concerned with is the belts since I've never done any work on motor components involving the belt...

is it simply pulling it on and off? or are there any kind of specifications I need to be concerned with?



On another note, I've had a bad oil leak for a while that the dealer has been trying to fix. I think they may have finally got it this last time, I picked the car up yesterday and thats when the noise started.

Is it possible that they sprayed degreaser some place they weren't supposed to and now that belt or area needs some lubrication?

The only thing that leads me to belive that thats probably not the case is that the nose only starts when you turn on the AC. And I'm positive its not the Fan.

Any ideas?

I was thinking about spraying some like wd40 on the **** but I'm not sure if theres any adverse effects to that... Dont wanna be inhaling that crap in the car for weeks...

Re: Cost/Difficulty level of working on the AC in a 92 Prelude

dont worry about smelling wd40 if you spray it on the compressor. the fresh air comes from the windshield cowl not the engine bay. if the compressor is reman than that is fine. if its new thats even better.

as far as the belt goes its a manual tensioner. you need to turn the 14mm bolt to loosen the tension. then simply take the belt off.

Re: Cost/Difficulty level of working on the AC in a 92 Prelude

not that hard, but dont get busted opening your lines in public, bc the EPA will eat you up. But, if you have you kinda do it in a secluded area. Slowly the lines connecting to the compressor until you hear gas escaping. walk away from the car until you hear no more gas. take off the two 12mm bolt on the high port and low port hoses. take off you're belt unbolt the compressor (dont lose the bolts they're expensive i paid $2 a piece) repeat steps in reversal, now add ac oil and refrigerant.
