Last time I replaced them was never.Bought this 300d 2 years ago and have never had an issue with the old glowers.I did realize after driving my other cars that the glow plug system will give you a sign that somethings up, one sign is the light dosnt glow as long or periodiacally,the second is a little longer to fire off.Luckally this morning I was starting from home base and was able to do the fix in about an hr from some old but still good g plugs I had lying around . Generally this time of year your stuck without a good working glow for start up.Im going in and replacing these with new ones this evening ,would hate to get caught in a mild flurry here in south Texas.Kidding aside ,you guys that live up north and are dealing with the harsh weather mother nature has dealt out ,keep safe .

It is also the time of year that tests the battery amperage, correct oil viscosity, fuel.......

Yes, I put in a fresh set of glow plugs in August so I would not have starting problems in the winter. I am looking out the window at very heavy snow falling, but even at -4 deg the car starts up right away.

I put in a fresh GP as soon as one burns out in my 617 engines but I did replace all the GP at the same time in my 603 engine because of the difficulty (taking off the intake manifold) to replace them. Actually by time I got all the Monarchs out, all the terminals were broken off.

No more Monarchs for me. I replaced them all with Bosch.

How does one remove the last (#6) Glow plug without removing the manifold? I have an 87 300d -turbo that has the #6 out... seems crazy to take everything apart but it seems tight on room there.

Hell has frozen over.

Now that is funny! Those that haven't gotten to "know" PEH over the years won't appreciate that as much.

kerry,

I started to replace the GP in the 603 engine because the GP were so bad, the engine wouldn't start. By the time I got the Monarch GP out, all the terminals were broken off. So it ended up that all the GP needed replacement.

So I didn't replace anything that didn't need to be replaced. Had any of the GP from the 603 engine been OK, I would have replaced them with new GP and used the older ones in my 617 engines as required.

Does that defrost Hell somewhat?

I must admit that I have found changing glow plugs on a 606 is easier that a 603. However, I am looking for a way to attach a 606 manifold with Velcro. That should take out 1-2 hours of time to change glow plugs.
