YACT: Anyone know about Ford Exploer A/C systems?

[GasX]

My Explorer's A/C doesn't blow very cold, so I think I have lost coolant. My question is, "Is the low pressure side the one with the accumulator or without?"

The guage I have only fits on the nipple on the accumulator, but registers the pressure as too high for the low pressure side.

I'd hate to think that the kit I bought (that says to only add gas to the LP side) doesn't fit the LP nipple.

If the accumulator side nipple is the right one, then why is it showing the pressure as too high?

try explorer forum

Thanks. Unfortunately, that forum gets about 10 posts per day, so I will have to wait for an answer...

My dads ranger has an issue too. The housing they used in them has a weird connector and over time goes bad and leaks slowly.

he just bought a bunch of cans for like $2 a can and adds one like every 2 months during the summer. If you look at the chart it should say like outside temp and then an area that is good for the device. Also i'd rev your engine to like 2000rpm so it is about what the pressure will be when driving

whichever pipe is bigger is the low side. IIRC R134 fittings are different sizes, so I don't think you can put them on wrong

Sorry I didn't see this until just now.

Static pressure, even on the low side, will be near 100 psi when the compressor is not running. When the compressor is running, the pressure will drop to 25-45 psi.

Put the gauge on and turn on the AC system with the car running. The compressor should engage and the pressure should drop. If you're low on refrigerant, the pressure will drop low enough that the compressor shuts off and the pressure will rise.
