Take it to a mechanic...
why does my ford focus over heat when i turn the ac on
on the 2001 Focus we found the low pressure port in the passenger front wheel well, hopefully this is consistent with the 2002 model good luck
Take it to a mechanic.
First, you have to know what's wrong with it. AC repair really isn't a DIY thing.. you'll be much better off having a qualified tech do it.
Look in the FAQs.
The AC recharge valve for a 2003 Ford Focus with a Zetec engine is near the firewall. It is the larger of the two lines going to the compressor.
its right in front of the passsenger side tire, you have to pull up the plastic part the covers the wheel
Turn your front wheels to the right. The charging port is behing the right front wheel, so I'm told.
Tires 33psi all around.
You need gauges to repair AC.
Take it to an approved HVAC shop.
Take it to someone with the equipment to do so.
The ac compressor clutch is mounted on the front of the compressor and is a replaceable part. However depending on the complexity of the clutch change out it may be overall better to change the compressor and clutch together.
On my Focus it is inside the fender liner of the right front wheel.
The low side ac port for a 2002 ford explorer is on the top of the drier assembly. It is located beside of the window washer fill bottle.
Switch it off
To recharge the AC on the 2002 Ford Escort ZX2 you need to use the low pressure fill port. It is located on the larger of the two hoses coming off the compressor.
Show me a picture of the 2001 ford expedition air conditioning and coolant.
it is located in front of the coolant reservoir
Check the ac compressor and clutch to see where the noise is coming from. Also check the compressor drive belt for wear.
Check the amperage rating. You should go no less than what's on the 2003. Cars without AC use less amps. If they both have AC, I'd say no problem, as long as the bolt-pattern matches.
The AC is pulling power from the motor. The oxygen censor on the motor may also be causing this problem as well.
All that you need to do is unscrew if from the suction side and replace it...........
