Should I ALWAYS have to glow??
What I guess i'm asking is, should my '78 240d 4spd be able to start in warmer weather without glowing first? 128,000MI on it.
Thanks! |

I've always felt like they just ought to as well... but the fact is, their age and design makes these Mercs tend to dislike non-glowed starts. I have no idea why they are so much more finicky than any other diesel I use... but yes, they like to be glowed whenever you can.

i disagree with busted. if your engine temp will still register on the temp gauge at at least 60*c i don't think you need to glow

batteries are cheaper than starters.
may as well glow.

Automatic Glow
Will not the Pre-Glow relay determine (based on the engine temperature) if the
Glow cycle is necessary? Trust your Mercedes.

first start in the morning... glow.
after that, it depends on the compression and condition of your motor... but I gotta agree... batteries are loads cheaper and waaaaaaaay easier to replace than starters.

I firmly agree with the last two (three?) posts. Starter motors are hard on batteries anyway and diesels are especially hard because of the high compression. That's why most Mercedes come with that huge battery. Anything you can do (like always glowing) to make it easier on the entire starting system is worth it, IMHO.

My 603 will start without glowing if it has been less than ten to fifteen minutes after shutdown. If it's been longer than that, there is a noticable cranking delay.

Once again guys, thanks for all the replies!!! One other thing, does the 'oil cap dance' check REALLY determine the health on the engine or not?? Isn't there always gonna be positive pressure once you release the cap???
Thanks again to ALL! |

It's the degree to which you have pressure that is the determinant. The more blow-by, the more wear is generally assumed.

I've never seen it, but I heard that a new engine can actually have a slight suction in the crankcase.
OTOH, I used to have a 351 Windsor (Ford) with so much blowby that it would push oil out the dipstick tube. I drove it like that for over a year.

I never used the glow plugs on my SD when it was at operating temp. The newer engines need a complete glow cycle every time you start them, but the older ones don't seem to.

I used to have cranking issues with my SDL. When warm.
After I advanced the timing a bit, it starts quickly, even after sitting for 4 hours! I never use the plugs after a morning start anymore, in warmer weather,

Once the engine is warm, get in and crank.

Yep, as long as the temp gauge registers, you're good do go on mine. Usually starts right up on the second or third rev with a warm engine and no glow.
