Question about 1993 Acura Integra Hatchback

1 Answer

Im not really knowledgeable about cars. How do I locate the low side pressure port? I am trying to add refrigerant to the car. Anyone that can send images would be great.

I tried the copper line and the refrigerant kept spilling out, so I think that was the high side.

AC is under high pressure and should be left for a qualified trained proffessional. The low side port is on the larger of the 2 lines. The system needs to be properly vaccumed and have any moisture removed before a charge is applied. You also need to put oil in the system for it to operate properly. Have a proffesssional do it.

Low pressure


Your not charging your asking about adding
to a system that has leaks
No leak to repair,you don't need to add
Have a shop do your A/C work
If you don't know where the ports are you
don't have the experience to be doing that
type work
You will let air into the system,ruin the system,
overcharge it & most likely buy the R134a with sealer
& that will ruin the system for good. Stay out of that
isle in the stores,anything but pure refrigerant & manifold
gauges to install it & knowledge & refrigerant charts is
not something a vehicle owner should even consider

How do i charge the airconditioner


On a Traverse the low side service port can be found on the return tube between the radiator and the engine down by the compressor. It is almost directly below the high side port ( about 2' below it).

You shouldn't be working on Air Conditioning

You obviously have no knowledge or training

Take it to a repair shop ,so you don't do more
harm than good & you will, if you try to add refrigerant
only to have it leak out & polute the atmosphere

Cannot locate valve to add 134a refrigerant in a 2000 lincoln navigator


What your looking for is called a service port. On a 134a system there are two of them, located in the refrigerant lines. One port will be larger diameter than the other. The large one is the "high" side and the small one is the "low" side. refrigerent is added to the low side with the system running. You really should use a manifold gauge set to see what the pressures are before adding any refrigerant. If the system has too much, it is as bad as not enough.

Audi A4 Ac charge valve.


On that year a4 and a6 there is no low side charging port. (sucks)
The way you charge those systems is by evacuating all of the refrigerant, then with the vehicle off, add the correct amount of refrigerant to the high side port (turning the compressor over by hand occasionally)

I cannot locate my low pressure switch on 1995 Corsica.


First of all, from the discharge port of compressor to the condenser(the device in front of the radiator) from the condenser to the metering device is all the high side or high pressure. From the metering device through the evaporator including accessories back to intake of compressor is the low side or low pressure.It is important to know that entrained in the refrigerant is oil for lubrication. The combination of pressure and oil could be a safety and environmental hazzard. I know on older GM models one could short out low pressure switch by jumping the low pressure switch with appropriate gage wire. This would temporarily permit one to add aditional refrigerant to system.The job of the low pressure switch is to protect the compressor from burning up due to lack of refrigerant by shutting the system down.. Now, if the refrigerant is low it had to escape, meaning a leak.(refirerants don't just wear out)Refrigerants are notorious to being determental to the environment. Older refrigerants contained hydrocarbons that destroyed or reduced the ozone levels to reduce this from happening strict laws of handling and recovering a/c refrigerants were enacted & exhorbitant costs were placed on the offending refrigerants.In order to save some some money some untrained or knowledgeable people are continuing attempting to repair their systems risking injury like permanent eye injury.Is it worth it? No one (I believe ) intentionally desires to be hurt.However, by attempting to do something that you haven't been trained on can make you more susceptable to injury or accident. An in a instan one could trade off perfect vision to partial or even total blindness.This is not to just to scare you but gives you an opportunity to weigh all the decisions prior to attempting something one might be unfamiliar with.Most of the accidents I've witnessed at home and work were individuals taking short cuts,hurrying or attempting something unfamiliar with.Not all accidents fall into this category but be aware rehab is no fun and often not totally complete. Lets not compromise your safety and the well being of our environment.

How do you put in refrigerant for air conditioning


refrigerant is added at the low side charging port, this port is located in the low side AC line from the AC compressor, it is the larger of the two AC lines from the AC compressor, you add until the pressure is stable at around 28-32 PSI with AC on.
