Video tutorial

In this video, you can see how to maintain the glow plugs on a Mercedes E-Class W211. Remove the engine cover and use long-nose pliers to take off the plastic cap. Then, with a 10 mm socket and extension, carefully loosen the glow plugs without applying too much force, as there is a risk of breaking them.

The YouTuber removes all six glow plugs easily because he treated them with anti-seize during installation and tightened them to 14 lb-ft, which is the best torque if you want to inspect them later.

This maintenance should be done periodically, approximately every 37,000 miles. Next, clean the carbon from the holes, as it can cause premature failure of the glow plugs, and ensure the threads are in good condition before reinstalling the glow plugs.
