Howdy, folks. I'm changing my GP's for the first time and while 99% of my questions have been answered by other threads, I have a couple more.

I don't have a Duraterm relay (it's a Mercedes relay, probably the original) but I did get Duraterm plugs. This won't be a problem, will it? I'm about 95% sure it wouldn't be but that other 5% is nagging at me...

Also, the old plugs were 11.5 volts, not 11 as Mercedes specifies for my car. The PO said he had just had the plugs changed when I bought it, which was January. Could this voltage discrepency have caused the short life of these plugs? I have taken two of them out so far and they do look fairly new, like the PO was telling the truth. The parts number for these plugs ended on '001.' I think the new ones end in '039.'

Also, this job was truly a PITA until I bought a 12 mm ratcheting wrench yesterday. If you have never done this job before, I would say one of these wrenches is a must.

I wouldn't use no name brands like Duraterm (this is the first I've heard of them). From what I've seen, Bosch or Beru are the best brands of glow plugs to use.

Duraterms are Bosch; they're some special type of plug that are supposed to glow for a few minutes after the car has started, to warm the engine that much more. I'm pretty sure I will not receive this benefit with my old relay, though.

Although the parts number does not appear on the Fastlane site, it appears Phil is also selling the Duraterm plugs for an '85 300D. The Bosch plugs that come up when you type in 'glow plug' while looking for '85 300DT parts look exactly like the ones I bought.
