How does a block heater work on a diesel?

Normally, block heaters are installed in one of the factory freeze-plug locations. This allows them to most effectively heat both the coolant and the oil at the same time. They run off normal house 110V AC outlets, and many times the plug for the block heater can be seen hanging out of the grille.

What are glow plugs on Mercedes Benz engine?

To guarantee spontaneous starting, the engine is fitted with ceramic glow plugs which attain a temperature approximately 200 degrees Celsius higher than metallic glow plugs (1250°C as opposed to 1050°C) and are virtually wear-free. Mercedes-Benz put these glow plugs into series production for the first time in the predecessor diesel engine.”

What’s the best way to remove glow plugs?

4) Slowly apply a gentle torque to the glow plug ( if needed just rock it back and forth, GENTLY ), they WILL come loose. 5) Loosen all 6 off at once, whilst the block is HOT, don’t worry, as once they are free you can then loosen them off later.
