The 1988 Jeep Cherokee air conditioning low pressure port is located on the air conditioning compressor. The low pressure port will be on the right hand side of the compressor.
The low pressure port for the AC on a 2001 Jeep Grand Cherokee is located on the accumulator, which is typically found near the firewall on the passenger side of the engine bay. It is identified by a larger diameter service port compared to the high pressure port. To recharge or service the AC system, make sure to connect your gauge or refrigerant canister to this low pressure port. Always ensure the AC system is off before connecting or disconnecting any service equipment.
At passenger side of engine, around coolant overflow bottle. Piece of tubing, with pressure port sticking out. Usually has cover, with L marked on it.
Jeep Grand Cherokee cooling system through the low port on the air conditioning compressor. Connect your Freon bottle to the port and discharge.
Should be the larger hose coming from the compressor sorry, 1998 in line 6, there are 2 a/c ports on this jeep. one is on the small steel line the other is at the side of compressor with a cap on the port which has a ..H.. on the cap.
if your talking about the a/c it is the one closest to the dryer or the round cilnder that your a/c hoses run into.
witch is the low side on a 95 jeep 4.0
The OBD port is under the dash on the driver side.
both hi and low should be on top of the compressor (if the same as 88 4.0).....hope this helps, Mike
A 1995 Jeep uses R134a, not R12. The caps are grey or black.
It is on the passenger side of the engine compartment right in front of the coolant reservoir. The shiny long refrigerant line has the port covered with a screw off cap.
Yes, it is under the hood near the battery.
