Where are the air conditioner ports on a Mercedes Benz?
Open your hood and locate the high and low pressure ports of your air conditioning system. These ports are located on two pipes that are attached to your condenser and are marked with an “H” or an “L” on their caps to identify which is which (high and low, respectively).
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 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.
How can I check my Mercedes Benz air conditioner?
Remove the cap on the high side and connect the red gauge to the port. You can remove the cap by unscrewing it by hand, the screwing the red hose onto the port. Record the PSI readings on the gauges and compare them to the recommended PSI ratings for your AC system in your owner’s manual.
What kind of refrigerant does a Mercedes C230 use?
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 C230 consists of a compressor that is belt-driven, an evaporator and freon.

Where is the low side service port on a car?
The evaporator is located near the firewall behind the dash, and directly under the windshield. The low side service port is usually in this line and will have a black or blue plastic cap that needs to be removed. On some vehicles, the service port is directly on the compressor.
Where is the low pressure air conditioner Charger?
The first step in recharging your system is to locate the low side service port (or low-pressure port). Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port.
Which is the low side of the AC port?
To summarize: Every A/C System has two service ports: A high side and a low side. When recharging with AC Avalanche, you will only use the low side service port. The low side line of the system will have a larger diameter metal pipe than the high-side.
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.
Why does my Mercedes Charger lock up while charging?
Only gas should go into the AC system, by turning 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.
