Mercedes CLS - Video tutorial

Model: Mercedes CLS C219, MK 1 - Years 2004-2010
Part: Spark plugs
Operation: Replacing spark plugs and cleaning cables

Gently remove the plastic cover protecting the engine by simply lifting it upwards after removing the air hoses connected to it. In order not to confuse the cables, disconnect only the first spark plug. Using a ratchet wrench, unscrew the coil sealing screw connected to the first spark plugs and slide the connection pipette upwards. Check the number on the spool and the number on the pipettes. At the bottom of the cockpit is the first candle. Before proceeding with disassembly, carefully clean the pits with compressed air to eliminate any dirt that could fall into the combustion chamber. Using the special spark plug wrench, which has a rubber hooking device, gently insert it on the spark plug head and unscrew it. Be careful not to let foreign bodies fall into the pit. Replace the spark plug with one of the same model by carefully inserting it into the well, again using the special wrench and turning it gently, checking that it is screwed on correctly. In case of effort, remove it and try again. The spark plugs must be screwed with a torque wrench, if you do not have the key screwed in without overtightening. Proceed with the same operation with the other spark plugs. Clean the pipette leads and contacts with an antioxidant spray before reassembling them.
