Recently having removed the non factory installed AC unit as it was done by a bunch of cowboys on my S2.

really crud job - didn't even have a solenoid to adjust rpm.
Couldn't access the spark plug 4 either as they didn't use the proper union. Wrong size pulley also (half the size).

Now looking at this manual about installing the cabin cooler condensor it doesn't make much sense where to place it. I can't figure the picture out.

Underneath the front middle dash???
Or above the heater in the bonnet compartment?

Any ideas?

I guess this manual applies to 33s manufactured before 1986. Your heater box,
and the centre console is are newer than the ones described in the manual.

Yes that's true. I wonder if there is any way of fitting it in (apart from the way it was put in before - under the right glove compartment!!). Maybe somehow underneath behind the centre console so it blows out through the 3 middle vents.

They made a hole inside the condenser box with a pipe going to the centre console.
The air was only flowing through 1/4 of the condensing grills inside.
No wonder it never worked!

And a condensor running of a pulley of about 60mm in diameter (instead of the 130mm or so).

oh yes he had put one external condenser radiator in front of the water radiator with no extra fans.
as you can imagine it overheated the engine in 5 mins.

Yep, as I recall we mostly discussed about it earlier.
IMHO the crank pulley was modified because of the missing
idle raiser solenoid. Without this compensation the engine
is not able to maintain the idle RPM with compressor engaged.
Therefore they changed the drive ratio from 1:1 to approx 2:1,
this helped the engine, but caused many drawbacks:
- reduced delivery of the water pump
- reduced current delivery of the alternator (constant undercharge of the battery)
- and finally reduced gas delivery of the A/C compressor, thus drops the cooling
capacity significantly...
So even your vent system is working perfectly, the reduced compressor delivery
not provides enough refigerant to the evaporator.

yes that's right.
Correct on all points there lonewolf :thumbs: you have a better memory than me!

That's why I decided to take it all out and either sell the system or start from scratch and do it properly as it was useless.

Not sure yet. It's a very big job and won't have time for a year or so to take that on.

But first things first, fire up that engine
:lol:

yes of course.
I don't think I'll have any issue. It was either an earthing issue (as I painted the back plate where it makes contact with the motor!!!) or/and a solenoid issue.

Friday night I'm sure it will kick into action.:thumbs:
