Hi guys!

I am thinking of removing the entire ac system on my STS 95, i dont use it or have any use for it!

I had to replace the bearing in the ac compressor in january after that the bearing failed and the axle got bent with the result that the engine didnt crank over cause of the drivebelt was stuck!

This ac system crap that are on every car i never had figured out whats the use for, in the short summers we have here in Sweden you dont want to sit in cold car when you have waited for the summer through the cold winter.

Is it possible to remove compressor,all lines, expansion tube and just throw this crap in the garbage container? Then just get the shorter belt to bypass the compressor pulley?

What about the electrical fittings...will it set a code when the compressor is removed?

Should be easier to replace the alternator if its neccesary in the future with the ac compressor gone!

For about a year, I had by-passed my compressor with a shorter belt and the freon was low and it just set a low freon code, not a big deal. I think you could easily remove the AC system especially on an OBD1 system.

The only possible drawback would be that your cooling fans would simply run in cycling mode and they would not be commanded to HIGH when you had turned on your AC. Having the AC on commands the cooling fans to high and the temps are more leveled

The only other issue would be that you would not have dehumidified defroster air, which might fog up your windshield given certain conditions

We can provide you with the length of the belt to by pass the compressor

Thanks BBF!

Do you know where i can get a exploded view of the ac system on a northstar? I am thinking of completly removing all components of the ac system, would likely be more room in the engine compartment after that when working on the engine!

Can you take out the compressor from the right wheel house?

The compressor will come out through the wheel well but you're not going to open up much room in the engine compartment by removing the compressor. Unless you plan on keeping the car until the wheels fall off, the next person to buy your car might want the A/C system functioning. Just some thoughts.

[Roger Martinsen]

The compressor needs to be replaced anyway due to the bent axle in it! With the compressor removed,would it gain access to remove the alternator from the wheel house after unbolting it from the back?

[BodybyFisher]

Here is an exploded view of the AC system, I would imagine that you could leave the evaporator in place

Thanks BBF!

That helped me alot:)

What about the "thing" mounted on the top of the coolant recovery tank, is it unscrewable or is it stuck with the tank?

That is the accumulator/dryer, it is held in place by a clamp and inlet and out let tubing, it comes right off... Its not on top of the tank, its shaped like a coffee can, and extends down.

The condenser comes off also

what do you suggest..shorter belt AC Delco part nr 6K739 or the bypass pulley(which seems like a little weak construction)?

I used that belt with no trouble at all for over a year, you might want to try going to the very next size larger, if its not too much, I found that belt to be a little tight, but it did work

thanks for the diagram of the ac system. it is very handy when i decide but need instructions on how to do this. anyone knows?

[Roger Martinsen]

Just checking...

The ac system doesnt include in any part of the coolant system,does it?

You dont have to drain the coolant system or interfear with it to remove the ac system? Or am i wrong?

Nope, no connection at all, other than the electrical connection to turn on the cooling fans, but nothing related to coolant

Thanks BBF! Its nice when you have experts online..
