W108, 250S Water Pump Belt
 

This weekend, my fan belt broke on my '67 250S. I figured since I needed to replace that, I would also replace the fatigued upper and lower radiator hoses, and thermostat. When I took off the thermostat housing, there was NO thermostat in there. Anyone ever heard of this? Is it ok for the engine to run without a (87 C) thermostat? Any comments or suggestions are most appreciated.
Thanks.

Thickheaded american car mechanics take out the thermostat because they know better than the engineers.

Put a thermostat in.

BTW, if the thermostat has a little BB on it (I don't think yours will), be sure to put that facing up and rotated such that it's at the highest point it can be.


Hopefully, the belt broke because it was old, and not because you need a new water pump or alternator.
