[MBZ] Changing glow plugs on OM602

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

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. Luther On Thu, 29 Nov 2007 09:28:46 -0600, Jim Cathey <[EMAIL PROTECTED]> wrote: >> Could you please elaborate on the resistance comment for testing glow >>

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. You should have a spare glow plug in your bag of tricks. See how your meter

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?

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 should
