I'm sure this question has been answered before but I've searched and can't find it anywere. I have an 84 Camaro with a TPI motor out of an 89 Caprice. So it has the computer and all that stuff. My airconditoner isn't any cooler then my normal fan so i'm going to take it out. Whats all involved in removing it? Does something need to be changed in the computer?

Thanks

John

 

Welcome to thirdgen.org.

Not to split hairs, but Caprice never got TPI. TBI, yes, but not TPI.

Anyway, the computer doesn't care if the AC is gone.

 

Woops, my bad, the motor came from the Caprice but the TPI came off of the motor that it came with when the guy who I bought it from got it. However, that motor was blown so they kept the TPI and put it on a caprice motor. Anyway the only thing I have to do is take the belt off and get all the hosing and stuff out of there and plug the radiador.

Well, '84 didn't get TPI, or EFI of any kind, so there's a little disconnect there, too.

But, can we assume this is the V-groove belt system? In that case, the AC belt can be removed by itself. It goes around the PS pump pulley as well, but I didn't have any belt slipping problem with mine when the AC was off for awhile.

 

I'd personally try and find out why the A/C isn't cold...I'd go mad if I didn't have mine. Then again, down here in the New Mexico Sun you kind of need it. Nothing like Hot wind on a 120 degree day to make you roll up the windows! hahaha

But to answer your question, well it's already been answered. See the above posts.

 

I really don't know, all I know is what the guy told me. That the old motor had the TPI on it, they swaped to motor out to one from an 89 caprice, then put the TPI back on it. The vin number says it's an 84 but it's got Z28 TPI badges inside, but those could be put on so I don't know.

I'm seventeen and don't know a ton about these cars, i've had brief experiance rebuilding a 305 out of an 83 camaro like three years ago, but your going to have to be more specific with the v belt or what not stuff. From what i've seen, the belt from the ac goes to a pully down lower on the engine, that has another belt comming off of it. I'm pretty newbish about this stuff but I'm willling to learn. So thanks for all the help you guys can give me. This forum has been a big help to me.

Run the VIN number on the car. That'll tell you what it is, what is has and all the options included.

Then, if you can get to it, run the numbers on the motor. Kind of hard to do since they are located on the back of the block but you might be able to read them if you get creative. Other than that, take a picture of your intake and post it. From the picture, we can probably tell you if it's a TPI or a TBI.

 

I've ran the vin, and it is an 84, so someone must of put the tpi badge inside it. I know for a fact that it is Tuned Port, because it says tuned port on the top of the intake. What about the belt? And am i going to have a bunch of freeon or what not spraying out at me when i take all the hoses and crap out? Another question: Will this give me more power and better mileage?

Thanks again

 

If you just pop your system loose, then yes, if it is presurized, then it's going to spray out. I still think you should spend the money and have it looked at by a professional (Or do it yourself) to find out why it's not cold. A/C rocks.

Most likely, your consenser is blocked, your freon is low, or your compressor is shot. /shrug Does it just not blow cold or does it blow cold for a bit then stop working?

Better mileage and more power?
Maybe 1-5hp and maybe 1mpg. HotRod did a special on it a few years ago (Can't find the article at the moment), but basically, there is little to no parasitic drain on the motor. Also, mythbusters did a show on it.

 

The blower works, when I turn the a/c on it blows the same temperature air as the normal blower does, no matter how long i let it run...so that leads me to believe that something is shot.... And being a 17 year old and having a 17 year olds budget, I figured I might as well take it out, gain some engine bay space, and a little power. However, it would be good to get fixed if I had the money.

yeah im removing my A/C system too. I have v belts so my compressor is running from the crank to the powersterring and up to the compressor. so i will be removing the compressor along with all the other ac stuff. I have leaks everywhere in the system and really don't feel i need it. even if i had it working i would only be using it like 3 months a year. not worth it to me

 

I'd take it in and have it tested. If it blows but it blows warm it's one of two things as I see it. Either

A. The system isn't charged.

B. Your compressor isn't engaging.

To check your compressor, open your engine bay and turn the AC on. Your AC Clutch should engage the compressor. Look at it carefully first when it's off and then turn it on. There will be a center part that when off isn't turning but when on starts to spin with the belts.

For the second, take it down and for like $20 or so you can have your system tested to see if it's charged. Or have sears or someone do the inspection on your system. They should tell you if it needs to be charged or if something else is leaking/wrong with it. Also, before you take it down to have someone else look at it, when you turn on your ac, let it run. ON the passenger side of the car is a silver cylinder. That's your accumulator/dryer. Put your hand on it. It should get cold...really cold. If it doesn't, either something is blocked or your system isn't charged properly.

Also, check your condensor in the front of the radiator and make sure it's not blocked.
