Hi, My beautiful second user MB 600 SEL was written off by insurance after travelling through a large puddle of water (- mid shin high). I was travelling at about 10 -15 mph and had no option but to go forward. The explanation I have had is that water from the bow wave got into the engine and caused the engine to seize. Has anyone else had or heard of this problem. I feel that this is a design problem or MB should publish this as a health warning to owners!! My older 230 TE estate regularly had to ford a small river without problems (although I did use to worry about the electrics gettin wet). Grateful for feedback.

Do you mean that water got sucked into the intake manifold? If so, water is very hard to compress and could cause enourmous cylinder pressures, which could damage the engine.

Hi, I too have a problem with MB design. My alternator on the 103 engine shorted out after I hit a puddle of water. The location should have been moved higher rather than placed at the bottom

Thanks

Yes, believe that water must have entered via the air intake and entered the piston chambers (is this possible?) and then since water can not be compressed damage will result - I had no idea that this could happen but my concern is that this should happen so easily - with such a small amount of water on the ground - is ther no way of preventing this? Thanks for replys!

I heard that Ford Explorers can also suck water into the engine intake. The air cleaner intake has to be low or water splashes up and into the air stream. I suppose that you could move the air hose and ensure that it is higher. Old Dodge trucks sucked air from the passenger compartment by the glove box. Not likely to get water there. As far as the alternator, it is mounted low on lots of cars. My 103 engine has a large plastic belly shield that looks like it might protect the alternator from splashing water.

Martin;
Yes in fact water can be sucked into the engine via the air intake.
If you look you will see the intakes at headlamp level.
This kind of damage usually includes bent connecting rods and damaged pistons, it is repairable but at great cost!
If you intend to repair that engine precautions should taken a.s.a.p. to prevent water/rust damage to other components.
