Cold weather exposes glow plug failures...
This cold spell forces us to address glow plug failures. It took me 3 hrs to change 3 glow plugs, damn they are hard to get to! Starts right up now in 15 degree weather, whereas I couldn't start my 83 300D in 35 degree weather before the change.

LUCKY YOU! I have two left that are literally spinning in place. Hopfully the remover tool I ordered will get them out. Ya gotta love, and hate, the 606's and their long arse GPs.
BTW, water pumps fail when I bring these southern diesels up to NY winters. Odd, but sees to be true. |

On two cars that I have purchased, including my current 300d, when I went to change the GPs I found that the #5 was older than the others. The last person who did the job either couldn't be bothered or gave up on the last one.

* If you don't enjoy walking in the COLD. * If you don't enjoy working outside in the COLD. * If you don't enjoy being stranded in the COLD. I strongly suggest replacing glow plugs at the first hint of cold starting issues during WARM weather. Note: Several of my local customers with OM60x engines have experienced the seized/broken glow plug issue (cylinder head removal), and now elect to remove the glow plugs for testing, cleaning, lubrication, every year as routine maintenance. .

this is just easy good advice
I took this advice about 5 years ago after moving to Wisconsin, and the 50 bucks in new glow plugs every year is a total no brainer if you are living up NOrth.
I do it on my UD diesel flatbed(best work truck ever) , and it started right up at -15 yesterday, with no block heater as that blew up last week. I did cheat and have a oil pan warmer on it though. You are out like 1 hour of your time, and maybe 20 bucks in replacing "sort of functioning" glow plugs, but this is cheap, easy insurance. Love to all, TheKid |

Okay, Guilty ! At least once a week for the last few months I keep telling my son " I need to buy some glow plugs and replace them before it gets too cold "( the current set is on their second winter ) As luck would have it I have been having to park the 300SD in front of a friends house until materilals are removed from my driveway. Well this morning it was 11 degrees without throwing in the noticeable wind chill factor. Now I thought this would not be a problem so I had the wife drop me of ( 2.2 miles away ) wearing my pajama bottoms, sandals and my over coat. She drove away and I tried to start the car ............. slugish etc.
Long story cut a little short. I climbed in my friends garage window and nicked his longest extension cord about 100' and plugged her in and waited. It took about 40 minutes for it to get warm enough but she coughed and started. Now that was the longest 40 minutes ever. My feet were frozen as I drove back to my house. I am installing GPs tomorrow and will start plugging her in at night. Thank God I installed a new battery last summer and did adjust the valves, just no glow plugs. Never again !

I can change #1 through #4 in less than 3 minutes each. #5 longer, may 10 minutes. The trick is have the wires easy to remove and use the correct tools. I'll probably never have to change mine again since going to a manual glow plug relay because they don't get used much except from a dead cold start.

This and I always like to loosen up but not remove the nut on the glow plug, so I don't lose it. on concrete, it's easily found, but on gravel.......

To get the glow plugs off (again they should not have been overtightened), Loosen them with a long box wrench first, then use 1/4 in ratchet and socket with universal and extension to get #1 through #4 off.

On a 617 I pull the hard lines and on a 60x I pull the intake manifold. No sense busting knuckles and using strange tools. Just remove what blocks them. I can do 617s in less than 30 minutes and a 60x in about an hour.

Exactly. I have one that goes from 12 mm to 8 mm so it and my 17mm for removing the hard lines to give operating room was all that was needed. i think I completed it all in 2 hr. and I used a needle nose vise grip to hold the wires while taking them on and off.
I'll never try to do it with the hard lines on again.
