SO guys i was thinking of removing my ac to save weight. but when i was in school, i was told that when you use ur heater the AC turns on too, because the evaporater removes the moister from the air (which i no is true)

My question is, does it make that big of a difference? like if i remove the ac, and keep the heater core will my defrost work anymore? or will there be too much moisture in the air for the defrost to work?

and my camaro is my daily driver, so i think i need the defrost. just today it kept fogging up cause it was cold n rainy

I bought my car with the AC removed and the heat and defrost worked just fine.

Turning on the A/C to dry the air with the defroster is just a convenience, you can live fine without it.

Apeiron

Think of it this way, They did make Camaros/Firebirds with No A/C and they still had defrost and heat.

my 86 truck came from the factory with no ac, just heat. youll be fine with no ac. but if you want defrost and heat, leave the heater core intact.

itsMikey

how would you go about removing the heater core? like wheres it at?

its in the dash. you have to remove the passenger side underdash piece, then take out some screws on the plastic cover piece to get access to it, there's tons of threads on exactly how to replace the heater core (or just remove it). but theres really no sense to remove it completely.

its how the ac works, the evaporator in the ac is wat cools the air u feel in the car (basicly). u ever knotice there is a pool of water under ur car when u use the ac? it from the evaporator, one thing it does is remove moisture from the air.

but thanks for the input guys. Im still wondering if i should remove it. lol its very tempting to take out all that weight sence i have a lame 305. anyone know how much the entire ac system weights?

It shouldn't weigh that much. The heaviest part is the compressor. Everything else is IIRC, aluminum. Just remove the compressor. Think about it this way. If you fill up the tank to go to the races, your adding almost 100 pounds of weight. 1 gallon weights about 8 pounds. Multiple 8 by the capacity of the fuel tank (approx 12 gallons) and you get 96 pounds. So by removing the compressor, you'll save about 5-10 pounds.

Apeiron

About 15 lbs from the compressor alone, 10 for the condenser. Maybe 30-35 lbs from the whole system.

Wow. That'll make the difference in 60 mph race for sure.

Apeiron

There have been more difficult things done to save less weight.

I bet. Removing parts to replace with fiberglass panels, the hood, removing all seats ecxept the drivers, no dashboard, gutting out the engine bay. The list goes on and on.

There is no way I would remove my AC from my daily driver just to save a bit of weight.

I just dont see it worth any noticeable gain anywhere. I will bet that some hot day while you are sitting in traffic you will wish you still had AC.

Just my opinion. Weight isnt everything. Especially not in a daily driver. If this was a race car then go for it. I just dont see why people remove it.

id rather add hp than remove the ac....

1986tpiiroc

I live in So. Fla and it gets HOT down here. I would not remove my A/C from my car. My buddy made that mistake about 5 years ago and regrets ever doing it.

Louis_84

well first off the compressor had been shot sence the day i got the car 3 years ago, so its never worked sence ive had it. and i used to live in so cal, and it got ****ing hot here and i lived lol. but more to my point, i want to save weight cause it cost less to remove an sc system then to fix it.

And when u make as little hp as i do then all the wieght saving really counts lol my car had 150 hp 27 YEARS ago, lol not alot then even less now.

Well the heater weighs about 5lbs, so remove the AC if it doesn't work, but you'll miss the heater core when your shivering and wiping the condensation off the inside of your windshield some chilly morning.

Don't ask yourself if you can live without it, ask yourself if it will make you want to drive your car less. IE, on that cold morning, when you feel like driving your camaro to work, and you step outside and realize how cold it is, and you decide to drive your boring nissan in instead. To me that isn't worth it to remove the heater.

I just finished hooking up the heater lines in my car for that very reason! It makes it so I can enjoy driving my car more. The next thing will be a bigger muffler, it will prolly rob a little power, but my ears won't be ringing after a half hour cruise, and I'll like driving it more.

So how hot would it get? I live in the true So Cal( 5 minutes North of Mexicali ). Last month we hit 111 degress and maintained 100+ degrees for about 2.5 months. And I havent had a AC system ever since I got my IROC in 2002.

I recently removed my complete HVAC system from my car and weighed it. All components, including the compressor and brackets, condenser, evaporator, receiver/drier, lines, R12, heater hoses, coolant, bolts, HVAC case (both sides), wiring, etc ended up weighing 80lbs.

No way would I remove the heater system from a daily driver.

Louis_84

lol wow 80 lbs! damn sounds like im gonna take out my ac then lol. but thinking about it, i think ill leave the heater in it lol

Louis_84

lol i lived near san bernardino, so still pretty south if u ask me, especially sence i was born and raised in green bay wisconsin lol

if youre leaving the heat, then you have to leave the box on the firewall (houses the blower), or get an ac delete box.

1986tpiiroc

Maybe if I were concerned bout mine being strictly for racing and was worried bout times, I might concider it, but being its just for fun and comfort I will keep it. It was broken just before the beginning of summer so I had the compressor removed and resealed and hoses all redone and recharged. Cools as good as these cars can do for the year. lol

As I stated, 80lbs was for everything. IIRC the heater stuff weighed ~15lbs.

they pop up in the classified on here every once and a while too. usually from someone who got tired of not having ac...

Louis_84

can i remove the evaporator without having to remove the whole ac plemtum assy?

jahblah

hello, not thread jacking, just looking for so quick and easy assistance on the same subject...ive deleted ALL my ac except the part beside my heater core..can i remove that without using a ac delete heater box. ive seen pictures where people just welded the hole closed but i still need my heat. it doesnt get UNBEARABLY hot here but i do need my defrost and heat. like i said, not thread jacking, just need some quick help. i even got my hood up and tools ready lol

Louis_84

lol im about to go look in my chilton book lol

travis401

iTrader: (1)

you can just weld the firewall yes, but only if you want no form of selectable air blowing in the cabin. meaning no heat, no ac, no defrost, no nothing. at that point you could remove all the air ducting from the dash too. youll also have to redo the coolant hoses to delete the section that goes to the heater core.

jahblah

lmao

ughhhh, well..heater box it is..thanks though.

does anyone make any aftermarket non ac heater boxes besides acdelete.com ?

my27kgame

is there an article on how to remove the core? i found a big puddle on the floor last week

It's pretty straightforward. Pull the passenger side hush panel and you should be able to get at the heater core access panel pretty easy. Been years since I did it, but it didn't take longer than half an hour
