No picture to show you, but it's on the right hand side in the engine bay either near the power steering pump reseviore or near the firewall (or somewere inbetween). Anyway, chargine the AC system is done at the "HIGH" side port (not the low side). I assume when you say 'fill' the unit, you're talking about "Charging the System with Refrigerant'?

not sure about the color, but the low press charging port is in the large AC line, the one that gets cold, the small line is the high pressure line.

SOURCE: 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).

Where is the low port located in the engine to recharge the ac for a 2008 Chevy Malibu LTZ 3.6 v6


The low pressure side to the ac will be the Schrader valve that is the smallest size. If you are recharging it yourself try to fit you valve on both valve and you will see what I am talking about.

You have not down the most basic test, does the system have a full charge? The compressor will not run if it doesn't. Have the pressures checked by a shop with AC pressure guages to see if the system is low. If the system is low on charge find the leak before recharging it

You found the high side port. The other line should have the low side and if it is not on there it might be at the AC evaporator which is a cylinder shape made of aluminum. The cap will have a L on it not a H. Do not force it on the high side.

FACING THE CAR, WHERE IS THE EXACT LOCATION TO ADD FREON TO A 1997 CHEVY MALIBU. WE FOUND A RED CAP BUT UNDERSTAND THIS IS NOT WHERE YOU SHOULD ADD. HELP .....


The low pressure refrigerant port is near the firewall2.gif, just after the receiver/dryer. You'll need a gauge and preferably an ac test manifold. You can use the manifold to add refrigerant up to the point where the system maintains the pressure level in the green area. There should be a blue cap on the low pressure valve.
I believe your malibu take's 12 ounce's of R134, don't over charger the system. You'll blow O rings and worst kill the A/C compressor.
Good luck and hope this helps. Here is a link for A/C recharging. http://www.geocities.com/vantaray/air_conditioning.htm
