A/C & HEATER SERVICE PROCEDURES FOR 2003 MERCEDES-BENZ CLK55 AUTOMOBILES
Imported Cars & Light Trucks & Vans -> 2003-04 -> Evacuating System -> Using Charging Station -> Using Vacuum Pump
Vehicle: 2003 MERCEDES-BENZ CLK55 AMG 5.5 V8 GAS
Using Vacuum Pump
Vacuum pumps suitable for removing air and moisture from A/C systems are commercially available. A specification for system pump down used here is 28-291/2 inches vacuum. This reading can be attained at or near sea level only. For each 1000 feet of altitude this operation is performed, the reading will be 1 inch vacuum higher. For example, at 5000 feet elevation, only 23-241/2 inches of vacuum can be obtained. The system refrigerant must be completely recovered before it can be evacuated. Damage to the vacuum pump will result if pressurized ...

FUEL FILTER REPLACEMENT PROCEDURES FOR 2003 MERCEDES-BENZ CLK55 AUTOMOBILES
Mercedes-Benz -> Fuel Filter Replacement -> Except 2003-06 E320 & E500 Sedans Less 4 Matic & 2004-06 E Series w/Gasoline Engines -> Fuel System Pressure Relief -> Removal & Installation
Vehicle: 2003 MERCEDES-BENZ CLK55 AMG 5.5 V8 GAS
Fuel System Pressure Relief
Do not smoke or allow an open flame of any type when working on or near any fuel system related components. The highly flammable vapor mixtures may ignite, resulting in serious personal injury.
Prior to disconnecting fuel lines, the fuel system pressure must be relieved to prevent accidental fuel spray.
After the battery has been disconnected and reconnected, some abnormal driveability symptoms may occur. The vehicle may need to be driven while it relearns its adaptive strategy.
- Ensure t...

TIRE PRESSURE MONITORING SYSTEM PROCEDURES FOR 2003 MERCEDES-BENZ CLK55 AUTOMOBILES
Description
Vehicle: 2003 MERCEDES-BENZ CLK55 AMG 5.5 V8 GAS
While the vehicle is being driven, the Run Flat Indicator monitors the set tire inflation pressures by evaluating each wheels rotational speed. This allows the system to detect a significant loss of pressure in a tire.
If a wheel's rotational speed changes due to falling tire inflation pressure, you will see a corresponding warning...
