I'm curious..how many times have you changed the "glow" plugs?

I replaced the full set (of four) at approximately 250,000 miles - not because of problems - just to be cautious.

Also, when Mercedes-Benz decided to bring the "Baby Benz" into the US in 1984, all of the 190Ds had engine block (not dip-stick) heaters installed for cold weather starting. As the forumlation of diesel fuel has changed over the years ... now having far less parafin ... they have not been used in several years.
