How can I tell if my car has factory A/C or some aftermarket system? Car is a 1970 Z. Looks like a York compressor, positioned lower left under the distributor. There is a small dial for the A/C attached to the bottom of the dash to the right of the steering column. Does not work at present.

Thanks, Mike

Mike,

The A/C on the 1970 240Z was not a factory option in US destination cars. The unit you are describing is the aftermarket system, usually installed by the dealer.

I have a similar system. Is there a manufacture's name or part number on the drive belt to the compressor?

Thanks,

Keith

Keith,

There is a plate on the compressor, under a lot of crud, that I will clean to read. Looks like a set of numbers. I'll let you know what the numbers are tomorrow. Nothing on the compressor drive.

Mike,

I would also like to know if there is a manufacture's name or part number on the drive belt to the compressor?

Thanks,

Keith
