what all is involved with deleting A/C and keeping heat? I was told that my heater core is in that oaffy black box that i want to remove and that i will need to get a box from an original non A/C car if i want to keep heat. is this true?

 

the heater core is inside the dash, not in that box on the firewall.. you'll need a 1LE a/c delete pulley, and a 1LE a/c delete heater box that mounts to the firewall in place of the other one. You'll also need to decompress the system before you start, which you should probably have some shop do. I had mine done and they did it for free.

there's another post about a/c delete halfway down the "tech/general engine" page if you want more info..

 

Yep you'll need to get an A/C delete heater box if you wanna keep heat so you have a place to mount the heater blower motor and hook up the connections. I have an A/C delete pulley and heater box coming in the mail.

 

is it possible to just remove the compressor and still have heat?

 

Yeah you can remove it, but you're gonna need the delete pulley so you can reuse the belt. However you're still gonna have that big A/C box taking up space.

 

im not so much worried about the space problem as being able to loose the weight of the AC compressor and not have to put it back on after installing my headers.

 

If you're installing headers, you'll need all the space you can get.

 

and thanks for the replies, i just noticed someone made practically the same post 3 days ago, the search function just wouldnt work for me
thanks again

 

I yanked my A/C after I totalled my car, back in '96. Everything was smashed (including the heater box!!), so I replaced it all with the pieces from my parts car. I reinstalled the heater/evaporator box to the firewall. I left off the accumulator (silver can on passenger side), the condensor (in front of the radiator, looks like a thin radiator), the compressor, and all the hard/soft lines. The a/c compressor plug got taped up.

On the a/c hard line on the passenger side main frame rail of the car is a high-pressure switch. This switch "opens" when the pressure in the a/c system gets too high. When this switch opens, the fan kicks on. (You can verify this by disconnecting the 2-wire plug from the sensor while your engine is running.) Sounds like a damn good spot for a remote fan switch, eh? Anyway, after removing my a/c stuff, I wondered why my fan was running all the time. I thought I put the car back together wrong. Looked in the GM service manual, found out the problem, and stuck a piece of wire into the connector- no more continuous fan.

The evaporator is still in the box on the firewall. I stumbled across a heater-only box in the junkyard last year; I'll be putting it on this screen. Fun fact- the heater-only box is metal!! The heater/evaporator box is some kind of fiberglass. Anyway, if you remove the evaporator from the firewall box, but keep the original box, you won't get heat, and you'll get fumes from the engine compartment (carbon monoxide = sleep = death), so leave the evaporator in the box. It doesn't weigh that much anyway.

Keep in mind, too, that the removal of the a/c stuff will also do two things- 1, by removing the condensor in front of your radiator, your car will stay a bit cooler. 2, the front of your car might raise up a bit, negating any lowering springs you've installed. This might be more significant for me, since I have a 2.8 V6, but I just figured I'd bring it up.

I'm much happier with the 260 (2 windows @ 60 mph) air conditioning anyway. Never used the a/c unless I was going to a prom or something- and those days are long gone. But then again, I -love- heat... you'll see me on a 90 degree day wearing jeans and a black t-shirt in the sun. Good luck!

 

wouldnt a belt for a non AC equipped car work, and does anyone have a part #.

 

a non ac car still had the ac delete pulley in its place.
