w210 fan shroud interferes with fan, overheats.

[veggiediesel]

The engine in my 1998 e300d shut down today while driving home. I pulled to the side of the road and saw my temp gauge was sitting at 120. I turned on the heat, popped the hood and took a look. Belt was fine, no signs of a fluid leak, and the electric fans were running. I let it cool for a while and cautiously started it back up. The temp gauge was at about 90 and I drove the last 2 miles home, never exceeding 110 deg.

A more careful look revealed interference between the fan and the plastic fan shroud. Evidently the shroud had warped quite a bit and a fan blade became wedged behind it, stopping the fan and (I believe) the water pump.

The shroud warped at the 9 o'clock position (while facing the vehicle, as if you could see through the radiator). The plastic in this area should lay flat against the radiator, but instead it raised away, causing the interference.

I trimmed away the offending portion of the shroud using a knife to score the plastic and tin snips to finish it off. The shroud went back into position easily, and I made sure all the tabs were properly seated in their mating pocket in the radiator.

So...

Do you think I did any engine damage?

Fan clutch damage?

Should I do any preventative stuff, like oil change, coolant change?

Thanks,
