Been throught the archives and still can't find the engine number on my 92 300D 2.5T. After 260K miles, I broke the spring for the poly belt tensioner and need the engine number to select the correct new one. Virtually all of the block is covered with accessories, injection pump, or manifold on the driver's side! There's a 1/2" X 1-1/2" flat spot on the block directly behind the fuel filter housing, but it doesn't seem to have anything on it unless the stamping is very light and I haven't cleaned it thoroughly enough.

Thanks for the help,

Reid

That's where it would be.

Are you sure you need the engine number and not the VIN?

Normally you need the chassis number for parts cutoff dates. It is the end your vin #.

On the Buy Parts page, it has two choices for engine number range for the belt tensioner spring:
-10-030482
-12-019162
It's just above freezing in my garage, so my enthusiasm for cleaning off the engine and searching for the number is not too great, but I need to get the part ordered. It was cold enough that I was zable to drive 5 miles home without overheating with the belt slipping though.

A quick spritz with brake parts cleaner should reveal the engine number. Nothing in the area brake parts cleaner will hurt.

If you know it's the original engine you can ask an MB dealer to run a VMI which will list the original engine number. Or send me your VIN and I'll see what the EPC says.
