SOURCE: how to replace valve cover gasket 1998 chevy malibu

The first step is to remove all the parts that are in the way of you being able to remove the valve covers. (Ex.: air intake, loose wires etc.) Then you will need to remove your valve covers (using basic tools) and be very careful to not let anything get on your lifters, which your valve covers protect. Once you have the valve covers off compare the new gaskets to make sure they are the right size. Then remove the old gasket and replace with the new one using a high temp gasket sealant (available at any auto parts store) to attach the gasket to the valve covers. Then tighten down snug and check for leaks after replaced.

SOURCE: AC Low Pressure location on 2004 Chevy Suburban

You find the AC low pressure at the top of the compressor, orientated toward you , facing the front of the vehicle. You can also follow the compressor line to reach the port.

The valve is covered a plastic cap covering it.
Near the compressor you find two ports, the high port and low port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports covered with plastic caps. Only one of the pipes will be cold, the cold line will lead you to the low port.

Regards.

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).

SOURCE: 2006 chevy malibu.... where is the egr valve

If it's a US car then there is not an egr on the 2.2L engine. I think some of the mexican and oversea's engines had them, but not here in the US.

Where is the air conditioner low-pressure valve located on my 03 chevy malibu


The low side pipe is thicker than the high side pipe. Just follow the pipeline starting from your ac compressor and then going to inside of engine firewall. I think on the right side( passenger side). Before it enters the firewall you should see the low side service port.

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.

Chevy malibu 2005 3.5 a/c orface tube location


Yours has a

thermal expansion valve (TXV). no orifice tube . look at fire wall where the a/c pipes go in look for this part .



The thermal expansion valve is located in the liquid line between the condenser and the evaporator. The thermal expansion valve is the dividing point for the high and the low pressure sides of the A/C system. As the refrigerant passes through the thermal expansion valve, the pressure of the refrigerant is lowered. Due to the pressure differential of the liquid refrigerant, the refrigerant will begin to vaporize at the thermal expansion valve. The thermal expansion valve also meters the amount of liquid refrigerant that can flow into the evaporator.

Where is the ac low pressure valve in a 2002 chevy mailbu


2002 Malibu is near the firewall on the passenger's side about a foot down. Really odd place and not that easy to reach. Obviously the design is not for DIYs. I have a Honda Accord and the high and low are side by side and very easy to service! Go Government Motors, well I guess it was the "old" GM them.

If you are gonna charge Freon, you are looking for the LOW SIDE pressure valve. Most of the time its located on the low pressure hose or the evaporator itself.Look for a HUGE black cap most of the time its that color your freon can if it came with a hose attached will only fit the low side connection.
