Where is low pressure port 1996 Jeep Grand Cherokee?

Answer 1

It is under the hood on the right (passenger side) of the vehicle up next to the fire wall to the rear of the coolant recovery tank. Do not turn the freon canister upside down when filling this port and the engine is running. It will cause liquid to go to the pump and destroy your pump. Make sure you wear safety glasses and gloves when you work with this, as the freon absorbs huge amount of moisture and it will absorb quickly into your eyes if sprayed or spilled. The high pressure connection is on the side of the A/C pump near the front of the engine on the left (driver's) side.

Answer 2

If you are looking for the Low Side Pressure Port for the Air Conditioning System of a 1996 Jeep Grand Cherokee Laredo, it is located in the back of the engine compartment on the passenger side almost in the corner, sticking up behind the Coolant reservoir.

There may be black cap screwed onto it. The port and the line (hose) it is connected to is unpainted aluminum.

This is where I've recharged my AC and flipped the bird to Houston's merciless heat.

Answer 3
