Question about refilling ac coolant in Focus 2002

[4my3boys]

Hi there,
This is my first post. We took our Focus 2002 to our mechanic this morning because our ac is not working. He said the coolant needs to be refilled but could not figure out where? Can anyone tell me where the cap is to refill the coolant? Thanks in advance for your help.

I have attached a picture of where to fill up, sorry this is the best one I could find, the port is located a little off the screen but it should give you the general location.

1. Turn the car on, turn the knob to MAX AC

2. Then connect the can and gauge to the port I have shown you. You have to unscrew the cap before of course.

3. Make sure that the gauge is not above 100 PSI. IF it is that means that the compressor is not working properly or at all.

4. Normally it should cycle between 20-25 to 40-50 PSI.

5. So if it is below 20 PSI you can fill up.

DO NOT fill up just yet, after you have connected the can to the line, unscrew it just a little as to purge the hose with refrigerant in order not to allow any air/moisture to get in the system. Moisture+Refrigerant = Acid

Then quickly screw it back on. Turn the valve to pierce the can and you are ready to fill up, while all this is happening the car should be kept running and monitoring the gauge is keeping between the ranges above.

Hope that helps, if you have any more questions let me know.

Go to the following page outlines where the port is (passenger side wheel well) and how to fill -

on my 2002 ZX3 the port in on the left side (driver) between the front headlight and next to the air intake tube. it stands up vertical through a hole in the crossmember and has a black cap on it.

He feels the motor - block, valves, etc. are sources for "crud" that ultimately makes its way through the cooling system and creates the filth in the radiator. He suggested that the only way to completely eliminate the problem was to tear down the motor and clean up the source of the dirt and matter. This is not advisable based on the age of the car and the costs associated with doing this type of major cleaning. He also said that he has seen cars with similar dirty radiator coolants run and last for years - provided of course the radiator is periodically checked and back flushed with new antifreeze added. Any opinion on this recurring problem and the advise of my mechanic. My daughters many miles away at school and I am naturally concerned especially when she has a 3 hour plus drive home alone when she visits during the holidays and breaks. Joe
