What should the pressure be on a Mercedes air conditioner?
Read the pressure in your air conditioner system. If the pressure is low the gauge reading will be in the white zone. If the pressure is normal then the gauge should be in the green zone. You should not have a reading on the HIGH / RED zone except when the car is turned off, in which case it is normal. Always keep the can UPRIGHT.
Why is my Mercedes’s Class W220 not charging?
Only gas should go into the AC system. If you turn the can upside down the AC system will get liquid refrigerant which can cause the AC compressor to lock up and also wash out the oil. Keep the AC refrigerant can in the up position and only shake it slightly while charging. If the refrigerant level is very low, the AC compressor will not engage.
What should the pressure be on a Mercedes Charger?
If the pressure is normal then the gauge should be in the green zone. You should not have a reading on the HIGH / RED zone except when the car is turned off, in which case it is normal. Always keep the can UPRIGHT. As you charge the system shake the can slightly every two or three seconds while you are charging.

What is the code for Mercedes Benz air conditioning?
Also make note of the recharged bar pressure (17) – you can periodically check code 7 to make sure the system is holding the refrigerant pressure – if it decreases over time you have a slow leak and need to address it. Hope this helps and good luck! 2001 E55, 1999 C43. thanks!

How does a refrigerant work on a Mercedes SL500?
Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant. The A/C system in your SL500 consists of a compressor that is belt-driven, an evaporator and freon.
What kind of refrigerant do you use on a Mercedes?
Or if you know you have a seal proof system or don’t like the idea of adding these additives into the expensive Mercedes-Benz A/C climate control system, then adding pure R134a or just one with only added oil will be the safest way to go. Recommended R134 A/C refrigerant kits for aircon refill?
How to recharge AC system in Mercedes Benz?
There should be a black dust cap on it and the lines will most likely be aluminum. Remove the dust cap, snap the R134a fitting over it (make sure it is snug), start the car and turn the AC on cold. With car running , release trigger to fill AC system with refrigerant. Watch the gauge……END.

How do you recharge a Mercedes Benz air conditioner?
Turn the engine on and let it idle. Turn the air conditioner ON and set it to the maximum cooling setting. Open the hood of your VEHICLE and locate the low-pressure AC service port and remove the cap. Attach the refrigerant gauge to the service port.
Can you add R134a refrigerant to an A / C system?
In many cases you can add R134a refrigerant and your system is back to working normal again. In this step by step guide we will show you how to recharge the A/C system using a R134a rechargin kit. This method is used to top off an A/C system that has been working fine for 5 or 6 years.
How to add Freon to a 1998 Mercedes-Benz SL500?
How to add freon to your 1998 Mercedes-Benz SL500: hook up the can of refrigerant (likely r-134a) to the low pressure port. When your compressor kicks on, add freon to the correct pressure. In addition to cooling, freon lubricates the compressor when it runs.
Turn the engine on and let it idle. Turn the air conditioner ON and set it to the maximum cooling setting. Open the hood of your VEHICLE and locate the low-pressure AC service port and remove the cap. Attach the refrigerant gauge to the service port.
Where can I buy a freon AC system?
You can buy R134a at any auto parts store, Wal-Mart, etc…any place with an automotive section will have it. You’ll need to buy a can that also has the gauge/hose/fitting attachment too. Fill the AC at the low pressure port.
Where does the gas go when recharging a Mercedes?
Only gas should enter via the A/C low-pressure charging port. When you attach the gauge, the pressure is on the red zone. This may happen because the engine is off or the A/C compressor is not engaged. You measure the aircon gas pressure and the gauge shows zero. This could happen because the system is very low on refrigerant.
