I have a 2005 chevy malibu and need to know which port to recharge the system through. The lower port (located near the firewall) or the upper port (located near the upper left side of the radiator)?

    Just to let you know to make sure he doesn't over fill the system as not only is it not good for the system but it will also cause it to run warmer. The old systems that ran on R12 freon had a set amout as far as pressure readings. R134a that is in your system you will need to run about 35 to 40 PSI if the hose your filling it up with has a gauge. The trick I use is to add freon up to about 35 - 40 PSI. I let it run and even rev the engine at a steady RPM (about 15 - 2000) and with a thermometer stuck in my vent I chack the temp. Then add a little more freon and do the let it run thing and rev then let it run at idle until the temp is steady on you thermometer. I continue doing this until the temp begins to rise. At this point I let a little out and that makes it at its maximum cooling. Of course don't go do high as far as pressure readings. R134a is picking and I find the pressure readings are different for every vehicle when just topping the system off. Glad I was able to help..

You didn't mention your engine size but if you have the correct tool to charge the A/C system there are 2 different sizes and the connector that you use to charge it with will only fit on the correct one as they are 2 different sizes. The 2 different connectors of valves like I said are different sizes. The one you use will be the smaller of the 2 valves. The hose itself is larger but the port you fill up is the smalled one out of the 2. The hose will only fit on the 1 that fills it.

A Ball Joint Can Usually Be Replaced Without Removing The Control Arm From The Vehicle. Place The Vehicle On Jack Stands. Remove The Shock Absorber And Install A Spring Compressor on The Coil Spring.Remove The Nut Securing The Ball Joint To The steering Knuckle And Separate The Knuckle And Then Joint. The Ball Joint Should Be Pressed,Riveted,Bolted,Or Screwed Into The Control Arm.A Service Manual Will Give The Details For The Specific Make And Model Vehicle.

Where is the low side port for ac charge located on engine for 2001 mountaineer


4.0L , 5.0L : Back near the firewall (Evaporator) above the accumulator/drier. The line will be cold /low pressure port.
Near radiator (Condenser) is hot/high pressure port

Be careful, if unsure do not risk it. If the system is leaking this will be a very temporary fix and probably needs the service of an experienced auto AC person.

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
