This thread is real timely. I just buttoned up my A/C system yesterday after it being opened for about a year. While the compressor itself was good the clutch plate was not. Two of the 3 caps had fallen out and I knew it was only a matter of time before it stopped working. I tried to get a new used unit but the 98-99 SE/SE-L compressors are different from all the others. I ended up sourcing a clutch plate from a B15 and it was identical to what I had on the car. I replaced all the O-rings on the lines and changed the dryer with a new Nissan unit. I plan on vacuuming, leak check and charging tomorrow. Hopefully it'll go well. @SE-RMonkey I'm looking forward to see how yours turns out.

I'm shooting to do this either this weekend or next, but I have to track down a set of gauges yet. I thought Autozone loaned them, but they don't list them on their website so a call to the store is in order.

You can get a set of gauges from harbor freight or northern tool.

I did see they're available at Harbor Freight for a decent price, but what are the chances I'll ever need them again? Guess I could unload them on eBay or Craigslist.

You could rent them out to people too

Hmmm, my dad has R12 gauges and it looks as if they can be converted for R134a relatively easily, and on the cheap!

EDIT: Called my dad and he confirmed the R12 gauges were hanging in the garage. Adapter set ordered for under $20.

You still need some way of holding a vacuum unless that is one of those old school hand vacuum tools.

^This is very important! Pulling a deep vacuum (25-30 inHg - inches of Mercury) on the system and holding it for no less than 15 minutes is a standard evacuation procedure. And please make sure you're adding refrigerant to the LOW SIDE! The low side will be the larger line...sometimes has an 'L' printed on the plastic cap. You don't wanna be the guy that discovers what happens when all that high-side pressure goes into that little can!
