I did the 240D first as the system was apart for an extended period of time. I vacuumed the system for ever and filled it with the cheapy Walmart conversion. The first can went in ok, the second died during the install. I then used my gauge/manifold set to top it off. The cooling fan seamed to come on after only running a few minutes, leading me to believe the presures on the high side are just a bit too high. Cooling was not adequate during warm temps (95 degreees +). I thought the Walmart stuff may have had too much oil and it was plugging or semi plugging the condencer. So yesterday I isolated the condencer and gave it a good flushing out with alcohol and gave it a good mlow dry. Vacuumed down the system again and added about two and a half cans. The fans still come on pretty soon and really not cooling as well as it should. I bled out some freon this morning and it's plenty hot out now. I'm makeing a trip to the hardware store and I may let out a tad bit more and see what happens.
Hoping for a cool ride
