2003 Ford Focus Refilling R134

Just noticed your question.

If you haven't already done the job, the fill is typically done through the low-side valve when using a shop system.

Your low-side should be under the front bumper on the passenger side.

The high-side valve is just on the right as you are facing the car. Just passed the fan shroud.

I've never use a DIY refill kit, but the manual should tell you which side to fill, high or low.

If it does, at least now you now which one is where.

(Please note: Not a mechanic. But have owned several 2001-2003 Ford Focus wagons.)
