OH! I forgot that we were talking about a UK car here! I know that at least my N. America car has all this emissions stuff! I bought the car with the a/c compressor in the trunk ( which was the only thing wrong with it) and was told it must be replaced so the smog pump would work!

The smog pump would be on the right side of the engine and easily visible (in line with the a/c compressor) if you indeed had one. And I am not sure if this is the case with an 83 but I seem to have some recolection that the a/c compressor has something to do with the auxiliary electric fan coming on? Maybe someone else could chime in on that?

I removed mine.........the car is my daily driver and I removed mine. No problems with the electric fan. I bypassed my fuel cooler with a good set of clamps and fuel line. I have had no problems and the car is so much easier to work on.

Removing Freon Compressor
> The smog pump would be on the right side of the engine ...
A Euro spec car has an idler pulley there instead. It can be left in place.
> ... compressor has... to do with the auxiliary electric fan coming on?
All Jags are wired such that the aux fan comes on by engine temp.
Some were also wired to turn on with the A/C clutch too. Removing the compressor will not affect normal operation of the aux fan.
To remove the A/C compressor:
Cut the drive belt and remove it.
Remove the wires from the compressor clutch.
Unscrew the HP line at the condenser fitting.
Unscrew the LP line at the fuel cooler.
Remove the cruise control belows and cap its vacuum source.
Remove two mounting bolts at the bottom rear of the compressor.
Remove two mounting bolts at the bottom front of the compressor.
Lift up the compressor and the attached hoses and take it out.
You'll now have less weight plus improved access to plugs A1, A2, B1 and B2.

I have done it taken off all the hoses and the compressor, took me only 1,5 hour. it is unbelievable but i found out that the first bougie on the left side never been connected no wonder the engine shaked. Now i have all 12 working and a beautiful place where after cleaning the mouse po and crude oil there is a beautiful engine.
thanks again.

I removed my compressor because the AC was non functional and it was in the way while I replaced the plugs and injector hoses. Aside from having no air conditioning in Florida, the only problem I had was a vapor lock during the hottest day of the year, about 101 degrees F. I got a bag of ice and laid it on the engine for 30 minutes.

1989 5.3 can i remove the lot
just been looking at this thread .because I'm in the UK iv never needed the air con on any car, so (by the way mine doesn't work),i like the idea of removing the air con completely, it seems the logical thing to do.less weight, one less belt to drive, more room,and got to be good for the spark plug removal,am not to sure on how much and how far i can go without compromising the rest of the car. ie, can i get rid of the radiator(compressor i think its called) that is in front of the normal radiator. My heater only blows cold air no mater wot the setting is on but I'm led to believe that the two are not related in any way

Pete,
I have taken my Arco pump ect off without any problems. For now i left the radiator and condenser in place. I also left the hose that goes from fuel cooler to fire wall (reason is that it is very hard to reach) Follow the steps above the one's from Don Neff and there should not be any problem. I'm taking the rest off now since I have a new engine to fit. let us know how it went.

Pete, you should be getting heat all the time since your air conditioning isn't functioning. There is a valve on the firewall exactly centerline of the engine. It may not be working. You can either change it out with a jag part or find a better one from a different car that will fit the same hose size. Some people have relocated theirs to a more accessible area, it is very difficult to get to behind the engine. I just put on a manual ball valve from the local hardware store. I turn it on in the winter and off in the summer.
