Glow plug connector repair kit for the Mercedes-Benz OM642 diesel engine. This kit allows you to rebuild the ends of the glow plug harness.
Includes six new metal contact sleeves plus 6 locking caps. Over time corrosion builds on the contact sleeves and the plastic caps no longer tightly grab the plug. Broken or worn clips and connectors can cause intermittent glow plug connection issues, leading to check engine lights and poor cold starts.
