Ok I need some help with the amount of freon in my safari. I recently replaced the compressor, front evaporator, and accumulator. I added the right amount of oil(I think), 48oz of freon like specd, and within a couple of days, the ac temp kept rising so I knew I had a leak. It wasn't enough to kick out the low pressure switch but I didn't know how much I had lost. To remedy the leak, I stuck on the high and low valves that come with the gauges and just closed them. Since then, the temps have been a steady 60 degree at idle, and about 52 on the interstate is the lowest I've seen.
Anyway, today I decided to add some more freon. The problem is I don't know how much to add. My problem is I don't really know everything about reading the pressures. Am I supposed to get the low and high pressure reading at idle or at 2k rpm? Before I added the freon, at idle, both front and rear fans at max, ac on max, the low side pressure was 35. I added about half a can(small one), and at idle the pressure jumped up to 56(low)/235(hi). I also took the reading at 2k rpm - 49(low)/285(hi).
All I'm going by is the chart that came with the gauges for 134a. All it says is 50-55(low)/275-300(hi) for an ambient temp of 90-100, well it was about 96 out and the van was idling in the driveway for probably 30 min.
Did I put too much freon in? I don't want to ruin the new compressor but the temps are still not as cold as my other 2 vehicles. I jumped on the interstate and it only got down to 48. I think I'm going to try and clean the condenser now with some de-greaser and see if it helps cool it down.
Any help would be greatly appreciated. Thanks!
