How to add freon to a 1987 Mercedes 190e 4cyl


You need to use a pressure manifold gauge:
http://www.amazon.com/Pit-Bull-CHIMG777-Conditioning-Manifold-Gauge/dp/B000VAQQ3Y/ref=sr_1_3?ie=UTF8&qid=1374522452&sr=8-3&keywords=r22+pressure+gauge
Connect the red hose to the high pressure side located in front of the radiator, connect the blue hose to the low pressure side located in front of the fuse box, there is a thick metallic tube that has a tire-style cap, unscrew that and attach it, purhcase R-12 refrigerant can of at least 1kg, then attach an adapter to the can and connect the yellow hose to this part, open up the flow valve and turn the can upside down while your car is running and the A/C is on.
Check for pressure, the high side should have a high pressure and low side should be as low as possible while the compressor clicks on. Google for the exact pressure numbers as I don't remember.
Just make sure that the AC compressor located at the bottom of the belts is engaged, this is engaged by the correct pressure setting automatically

Air conditioner does not cool in 2000 Yukon.How do I check freon level and how to replace freon if need be


Get an r134a refrigerant add kit from Walmart or your local auto parts store.

You can even get a can of Arctic Freeze by Intermatics that has a hose and a gauge on it.

Connect the hose to the low side port. You can find this port on the 'thicker' piping that comes off of the compressor (versus the thinner piping that comes off the compressor which is the high pressure side).

Pressure should read 25 psi to 45 psi on the low pressure side when the compressor is running and the a/c is on.

Pressure should read 75 psi to 100 psi on a hot day when the car is off.

However, you'll want the a/c to be running when you add freon.

Press the button on the can to install more freon, if needed.

Where do i put freon in on a 2005 focus


Your focus should not take freon. Freon is used in older cars from 1995 on back. Your focus should take R134 and the plug for your AC should be located under the passenger side wheel well (yes ford makes things so convenient). Just unscrew the little plastic crews in you wheel well and attach the gauge and can of R134 (should take a little more than 2 large cans).
