You do not work on any A/C system or attempt to add refrigerant

Have to have a trained professional with proper equipment work
on it

If you feel you need to add refrigerant there is a reason it leaked
out & is polluting the atmosphere that is all you will do if you try to
add to the system you will let air in overcharge & ruin the system &
may hurt yourself

Unless you have a manifold set, you use the low side port with the do it yourself recharge kits.

I am trying to locate the low pressure port on my 2000 Saturn LS. there is no cap on the only visible and accessible port I see. It is located in the front of the engine compartment (passenger side) but...


The high pressure port is much larger than the low pressure port. It is impossible to hook a charging hose to the wrong port. If the charging hose is leaking, it is either because it is not clicked all the way on the port or the charging hose connector is defective.

The high pressure port is located on the discharge hose just to the rear (driver's side) of the A/C compressor.

Where exactly is the low port for the air conditioner on a 1998 Pontiac grand am


Normally you cannot charge the high port as the connection will not fit. Also if the A/C is working the high port gets much hotter than the low port. Also on the plastic cap it will have an L on the low pressure port and an H on the high pressure side. Do not try to recharge it unless you are 100% sure. If you are needing to recharge the system then it has a leak that needs to be repaired. It is technically illegal to add refrigerant to a system with a leak without first repairing the leak. So, my advice is to get the leak fixed first and then have the system charged by a professional with the proper equipment and training. But the choice is yours.

Low-pressure port I need identification


Basic AC system consists of Compressor pump (on engine), Condenser (front grill with radiator) and Evaporator (Firewall). Pump has two ports output (high pressure) and return (low pressure). Follow lines from pump. High side is usually between pump and condenser. Follow lines and find second port this will be low side (refill) port. Paint or replace port caps (red high, blue low). Also, refrigerant in system determines port size (R12 or R34).
