Default York AC on Volvo 245 1975

Hello everybody! I'm writing from Italy and I'm owner of Volvo 245 1975 with B20A motor.

I bought a York compressor for my car and i would like to know if anyone help me to understand what I also need.

I also need the correct wiring diagram for the AC system, anyone can send me a photo? I need particular relays?

I also see that for B20 i need the double crankshaft pulley, right?
Something like this?


Thanks everybody,
Davide

The a/c compressor belt drive also uses an idler pulley to handle the belt tension adjustment.

You can check the volvo parts catalog at gcp.se. That has all the original volvo parts catalogs on the site.

No pictures but there are probably some on the web. Sorry it was a long time ago when we had a 75 245. Our first volvo that we got and that was back in the 80s.

Anyone know if It's possible to fix a double pulley from Volvo 164 with B30 motor on my B20 motor?

Most of what you need to know, and then some.

No, 164 crankshaft pulleys are different.

You can use any 2 groove pulley that fits any B18 or B20 and I have several styles of both. I also have some of the compressor mounting brackets, but I'm not sure if I have a full set of the mounting brackets.

FYI, to really make your conversion easier, you really should find a parts car that has what you will need to add A/C to your 1975 240.

Here in the USA, we didn't get carbureted 240's so I have never seen 1 and the pulley system is different.

For instance, all USA market 1975 Volvo 240s have an air pump for air injection for emissions control and AFAIK, those were not used on the carbureted B20s. And the air pump was driven with the same belt if it also had A/C.

Do you know if this pulley is correct for my B20? The third groove is for powersteering?

Yes, that 3 groove pulley will fit.

And yes, the 3rd groove is for power steering.
