## On the job

### Cold starts and clean warm-up

Heats the combustion chamber for cold starts and keeps glowing after start-up to cut smoke and noise while the engine warms. This one has an M8x1 thread and a 7 V element and is tightened to a maximum of 12 Nm. Bosch lists it for the Mercedes C-Class W205.

### How to change them

Old glow plugs seize in the head, so soak them in penetrating oil, work them out with a torque wrench and stop if the torque climbs; a snapped plug means a drilling job. Replace the full set on the engine, and test the glow-plug control unit and wiring while you are there.
