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.

Can a block heater be used in a garage?
The block heater was an option when I bought both my ML550 and GL320. I’ve never actually plugged it in though as I park in a garage and BC winters are relatively mild. I recently gave the GL to my sister who lives in Alberta where the winters are much harsher and colder.

Why do you need glow plugs on a diesel engine?
The lower the compression in the cylinder, the less heat is generated by the piston compressing the air. Hence, the need for glow plugs. They take electrical current and heat the glow plug element, giving the engine a little help when its cool.
