It could be that your water pump has siezed up - that makes a squealing noise. That would cause your engine to overheat, causing coolant to overflow, and oil to smoke on the engine surface.
1. I don't know about the general lifespan of MB water pumps. Ford & Toyota would be lucky to go 100 Km.
2. On old engines there is often some oil on engine surfaces from slightly leaking seals, etc. With overheating, this would start to smoke.
3. As you stated above that you did lose coolant, it seems that you did overheat.
I would focus on the engine cooling system. All your belts OK? Thermostat OK? Radiator blocked? Do the rad hoses look the right size? A rad blockage could swell the diameters.
If you re-start the engine now, is it still squealing? Can you locate the source with the hood raised? :thumbsup:
ya everything is correct as i stated above, but this morning i did start my car and the center belt wheel is wobbling... what does that belt turn???
so i guess the squealing is coming from that, there is still the coolant leak which i find odd if the water pump isn't making that noise. anyone know? thanks for the response keyhole.
I thiink you are referring to the 'serpentine belt', that MB call the poly V belt.
It should be under tension from a tensioner pulley (item 7). If any of the pulleys is wobbling that is your problem area. The power for the belt system comes from the engine crankshaft (item 1). If the belt is loose, you will lose your a/c, generator (alternator), power steering, water pump etc.
The odd moment you are looking for a solution to your problem and find yourself 5 year ago with a similar problem.

The water pump pulley seems to have seized up (all pulleys are spinning except the water pump pulley)
Hope shes OK
