Hello.
I got a question for your guys that might know the answer. My 200SX SE-R had the AC compressor working just fina with very very cold air but it was removed when we made the swap and, as a result of not being properly taken care off, it got contaminated and it's not working well any more (makes noises and poor cold air).
I decided to buy a good one from another member from the forum which is supposed to be taken from a 97-98 model (I quite don't remember now well) but problem is when we tried to install it, it did not fit on the entrances of the hoses. It seems it has smaller diameter holes for the hoses and makes it impossible to use it as is.
My AC compresson (original) has a stamped number on top that says 97 which I believed it was the year it was manufactured to be used on a 98 model, however, the compressor I got from the forum member has printed number 99 which I believe it's for a 99-00 model and this is why it changes.
The reason I ask is because I want to be 100% sure that year is that compresor made for as I had the idea all 92-98 we using the same and they changed on the 99 models..
Here are some pictures for you to see & understand me better
My 1998 200SX SE-R Compressor

It has 97 stamped on it
The unknown year Compressor received (has 2 connectors instead of one)
It has 98 stamped on it
BOTH SIDE TO SIDE
Top is Unknown year reveived (98 stamped) bottom is mine 200Sx SE-R 98 (97 stamped)
Left is Unknown year reveived (98 stamped) Right is mine 200Sx SE-R 98 (97 stamped)
Would you please be so kind to tell me to which year does the dirty and with 2 wires AC compressor belongs to?
Thank you
Luis
