I would replace the orfice tube if it has one. Then pump it down. The port should be on the back of the compressor. I have a 93 240 I can go check it if needed. You can barrow a vacuum pump from autozone. When filling with freon, make sure you bleed your gauge or you will get air in the system (not good.)
You really need to get high side guage on there. Ive seen where the low side looked fine but the high side was sky high. If you need help you can call me and I will walk you thru it. But you need some gauges (autozone loaners if needed) and a vacuum pump. And some patients.
