AC low pressure port 2001 Ford Ranger 3.0L

On top of AC Accumulator

You have the right port if it fits the RECHARGE hose. If it's reading 130 psi, it might be way overcharged.
Did you follow directions and did the AC compressor clutch kick in? At that pressure,on the low side,the compressor shouldn't even engage.
To discharge the system if overcharged,you need for a shop to do it. don-ohio (:^)

You only got two hoses going into & out of the
evaporator on any vehicle with A/C

You surely can follow the larger suction or return
hose back to the compressor, if you have to

You have to be able to see the dust cap on the
low side port. Could be Blue in Color

never been fortunate enough to be able to look under the hood of my dream car, but if it were my bmw , i would look on the left hand side of the auto, near the firewall for a port sticking up. probably has a blue cap on it. the low pressure side will be between the ac compressor and the firewall. not the port by the radiator thats the high pressure side.

hmm ..if you are looking for the low side air conditioner port .. then locate the condenser (thats in front of and looks like the radiator) .. you will notice two tubes going to that ..one is large the other small .. the small tube is the high pressure side .. the large tube is the low pressure side ... follow the large tube back until you find a cap that covers the low pressure port .. thats where you would fill with new refregerant (r134a) .. if you buy r134a, you can also get a filler hose and gage.. that hose will only hook up to the low pressure port ..it wont fit the high pressure port ...

Its on the Passenger side of the engine bay between the strut tower and the valve cover. It should have a blue cap on it, or maybe a black cap. Follow the ac line coming out of the back of the compressor and youll see it.

There are two aluminum tubes coming out of the compressor. The high pressure tube goes to the condensor in front of the radiator. The low pressure tube is the other tube, and the port has a black plastic cap over it, on the low pressure tube.

Pass -side under the hood,.ook for a silver tank looking thingy - follow the lines (pipes)- look for a black plastic cap. Down a bit below the top.

there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi

The low pressure port is located on the passenger side next to the fire wall. It will have a blue cap.
