Hi

I was driving the 240D on the freeway last Friday, when suddenly the alternator bearings froze up and shredded my fan belt.
I kept driving at about 65 mph, expecting the engine to overheat soon.
To my surprise the temperature only rose to about 95° C.
So I kept driving for 50 Miles until I hit Las Vegas city traffic and had to slow down.
Then at once the temperature climbed to 110° C and I had to shut the engine of.

At a speed of about 60 mph there is enough air flow through the radiator to spin the fan and the water pump fast enough to keep the engine temperature in acceptable limits.

I also found that the heater didn't work.
The water pump didn't spin fast enough to force the coolant through the heater core.

Nice to know that you can drive this old Diesels without a fan belt, as long as you drive fast enough.
