I never use my A/C cause first off it doesn't work cause only hot air comes out (this may be cause i need to refill it). So i was thinking maybe i take out my A/C system. I have two questions,

1) How difficult is this, let's say compared to installing springs and coilovers?

2) How much weight does it reduce?

 

Compared to springs you won't have to remove the wheel

Its not worth your effort. Just dont have the A/C on when you want to go fast. I'd say it would take off 50lbs.

 

Yeah but if a person never uses the A/C, taking off 50lbs is alot for a super light CRX. That will make a difference. A small difference no doubt but nevertheless a difference. Taking off weight really helps a light car like a CRX.

Also, how difficult is this?

 

I've done a few of these. Total weight saved is about 42-45lbs. I HIGHLY recommend doing this because on a 2000lb. car, that is a good chunk of wieght to remove.

As for difficulty, its pretty easy. A couple of bolts are hard to get at on the compressor. Removing the radiator makes the job MUCH easier but is not totally necessary. Use this as a good excuse to do a coolant flush and pull the radiator out (only takes a few minutes).

All the engine bay stuff will then come out quickly. One tricky part, but well worth doing is removing the evaporator from behind the glove box. It weighs 5lbs. Once you remove the glove box, you can remove the black ducting that holds the evap. Simply remove all the snaps and screws that hold the two halves of the ducting together, toss the evap., and put the duct back together and back into the car. There will be a small hole in the duct that allowed the lines to pass through, just cover with some duct tape.

Voila! your done and have removed a BIG chunk of weight from the front nose of the car.

Enjoy!

 

If you ever plan on putting the A/C back in, I would suggest just removing the A/C compressor, since this is a significant majority of the weight and is very far forward in the engine bay. Then just seal off the hoses you disconnected from the compressor. This is much easier than removing all the lines, which don't weigh much and are pretty hard to get out, and even harder to get back in.

 

i've removed all the a/c components in just the engine bay before, the total weight was a little shy of 50lbs

 

My engine is coming out this week, the AC is coming out for good if anyone wants to make any offers on it. It does not blow cold, but I have never tried to get it to. I bought the car a month ago, the AC wasn't cold, I'm going ZC Turbo and need all the room I can get up front.

 

then there's that square cast-metal plate (that the a/c compressor bolts to) that's mounted
on the engine. I took mine off, and it must weigh 15lbs easy. In fact, it kind of worried me,
becuase it seemed so heavy that I thought it might have something to do with the block's
integrity; that's silly, right???

 

I took out all the A/C crap in my Crx during the ZC swap. Like the other guy said before. . .with the radiator out of the way, it's way easy to get to everything.

The only thing I haven't gotten to yet is the part behind the glove box. But from what people say, it's pretty easy. Meybe I'll finally take care of that next weekend. I'll let ya know how it goes.

 

You know i don't use the heater either, so if i took out the heater, how much would that take off? And also, what is the difficulty of doing this?

 

do you want to sell it ? it's hot in houston.

 

I really would like to take off the heater core and the main components of the A/C that weighs the most and is fairly accessible (if that is possible). I have a Chilton manual and i still can't figure it out. Is their any website that you guys know of that will give me the best instructions on how to remove these two systems? Big pics would be best, he he.
