If you're sure you want a new compressor, I'm not sure which brand is better, or if they're all about the same. I am using a Four Seasons evaporator core and TXV in my Civic, but that's probably not comparable to a compressor. I'm still running the OEM compressor with R-134a and PAG 100.

I'd recommend you try out the one you have first, though. Unless you just want to go spend $250+ on a compressor. If you want to try out what you've got, inspect the clutch on the compressor per the manual. If it checks out, clean out all the lines with brake parts cleaner and compressed air, replace all the o-rings and the receiver/drier, hook everything up, and pull a vacuum. If it holds the vacuum, add refrigerant. Worst case is that if you were right all along and the compressor is somehow bad, you're only out an hour or two of work and about $30 in R-134a, instead of $250+ for a new compressor.

For the bolts that hold the compressor to the bracket, I'd recommend going to a junk yard and getting some off a Civic - I think 88-00 should be the same for the bolts.

 

Ok I got the ac compressor Out the clutch seems pretty much frozen it's been off so long I figured as much so I guess I will bite the bullet and replace it the southern heat is no fun to deal with
