Mk3 golf A/C in to VR6

[TC94VR 0]

Is it possible to fit the air conditioning out of a 1992 td golf in my corrado I have got a completely stripped shell and a doner golf and now seems the perfect time to fit A/C. My question is does it fit and what other parts do I need I know that it is not going to be straight forward as I have fitted a mk5 R32 lump but I am sure that someone else has done it before. Many thanks for any help cheers.

I'd say you'd be far better off keeping the R32 engine-side stuff (if it fits), and fitting the MK4 climatronic heaterbox and controls. I'm not really sure there's much, if anything, that you'd be able to use from the MK3 TDI setup.

Ok but does it take much hacking of the dash to fit?

Not a great deal but there is some 'tailoring' involved - mainly on the heaterbox itself. The main bits of work on the car/dash are cutting into the bulkhead for the A/C pipes, and shorterning the glovebox/lower dash tray, which you'd have to do whatever A/C system you fit. I don't think I did any cutting to the dash itself, and the climatronic controls are a perfect fit into the centre console.

 

It's not an easy install by any means, but well worth the extra effort.

Thank you

As for the pipe and the condenser is the mk3 the same or do I have to get parts specially designed and made for the job.

It's hard to say with the pipework - it'd be worth seeing what fits from the MK3 and then going to Piritek for the rest. Bear in mind you'll also need a drier and pressure switch in line (or I think one of the MK3 items has the pressure switch housed in the drier). Either way it's recommended that you buy a new drier and don't reuse the old one.

 

The MK3 VR6 condenser fits perfectly on the Corrado rad and the brackets line up, but the bottom pipe fouls the VR6 subframe. No idea on the TDI, but could be worth lining them up to see where you're at. I'm still at an impasse with the condenser on mine - I am probably going to have to make up my own brackets and get a generic one that fits.

 

There is a 4 cylinder and 6 cylinder compressor on the MK3/B4 Passat/Corrado but I don't know what the difference is. Possibly the pulleys?

 

Your biggest headache is going to be the wiring - I worked out the pinouts for a standard VR6 with a late fan controller, but if you've ditched the VR fan controller, you're going to have to work it all out again, and also work out the wiring to the ECU (the last bit should be easy - it's just a signal to increase the revs when A/C is activated).

 

I made some notes from my install here:

I've always meant to tidy the notes up at some point, but hopefully it'll give an indication of the work involved.

Cheers will have a read through.
