While I am waiting for the new radiator to arrive I thought I would get
on with doing other things on our '93 E300D/2.5 Turbo.
This, of course, has brought up more questions!
Does one need to remove the air intake crossover?
If one does remove it, does one need any new gaskets?
Any other sugge

That link is quite accurate.
With one exception, the ultimate test is using a current meter.
They should draw about 20 amps initially.
Seeing it glow to me is not definitive.

I'll second the 30-0-30 ammeter. If the current use doesn't drop to around
10-15 after a few seconds, it's a bad plug. That's all I use.

Parallel plugs measure about 0.6 ohms cold. And your meter has
to be g
I had some that tested fine cold but when heated they did not do well.
Pulled them and found that a lot of the tip was eroded away, so there
was still continuity but not a lot to heat. Replaced them and all was
OK again. Also put in a new fuse, was like $3 at the stealer.

When I was wondering if one of my GPs were bad (they were new) I pulled them
out and attached a battery charger to each one - if they glowed red hot
within about 15 seconds I considered it good.
Good luck -

The Bosch Duraterm and the equivalent Beru plugs vary resistance based
on temperature. They start out ~ 0.8 Ohms cold and go up to ~ 30 Ohms
when hot. All the bad ones I've seen read infinite ohms and don't get
hot anymore.

The crap is inside the prechamber, not the main cylinder. The usual
instructions have you crank the engine with the GP out to blow the
loosened crap out the open hole.

The three that I am pretty sure are bad measured somewhere in the
neighborhood of 50 ohms. I was using
an anolog meter, so I don't know, but it was on 100 ohm, and it
stopped around the middle. One and 5 looked like they were around 1
ohm.
If they are carboned up they will be tougher to get out?
So what resistance did you measure? Some meters might not give
accurate readings?
Well mind given your other comments likely they are bad.
Disconnect the wires, don't drop the nuts, use one of those racheting
wenches.
If there is not a problem with carbon buildup they should just
unscrew. Ot
Ok, the reaming is actually something I have heard of, but never really
understood what is being done. Its not cleaning the threads, its actually
cleaning further in, as in in the chamber, am I correct on that? Doesn't

use a 12mm ratcheting box-end wrench to make access easier - hard to get to
with sockets. Thread the new ones in by hand - last thing you want to do is
cross-thread the holes.Some people put a little oil on the threads, some
don't - I think the torque ratings for the plugs are for dry threads.
Today I went outside with my newly liberated meter, and found that 3 of my 5
glow plugs seem to be bad. My glow plug light stopped working a little
while back, and I have not been able to check that out until now. I
measured the impedance of each one at the relay. So, I'm figuring that I
