In short....normal.
The red warning mark on my gauge is well over 120, it could be 130 or 140, no figures there.
But the needle has alwasy been between 80 and 90 and judging by the info above, no one ever got near to 120.
Overheating must be a very rare issue.
did you really check that you have engine vibration? What about vibration of the fan?
Faulty mounts do cause vibration, noise, but do not affect the temperature.
I cannot see normal temperature causing vibration, maybe the other way around. It is anybody's guess, but vibration might ill-effect some sensors. ??
I would rather check what is the rpm when you get the vibration, it is engine related.


I would expect the fan to come on sooner - that sounds like too much up-and-down.
I live in the middle east. I drove my E240 (W210) 2002 all the way to Saudi last February covering over 3000kms. The then average Winter temperature was around 23Deg C. During cruise, the pointer remained fixed at 80 marker for several hours. If I'd slow down, the pointer would rise a little over 80. The marker hovered between 80-90 during stop and go traffic.
Now I have s320 (W220) 2002 and this is doing the same thing. The marker shows a higher coolant temperature at 90 marker but keeps fluctuating.
Thanks
- grease or oil on fan motor
- new pulley separate from the motor
Thanks!

Is there anyway to make the fan speed permanently high??? Temp here in UAE goes to almost 50 in this time of year, and in city its not bearable to sit in car with ac blowing hot air, Have to stop on fuel stations to sprinkle water on condenser. Got new compressor, Expansion valve, Air drier, Fan relay.
Want to speed up fan permanently or going to fix an extra fan in from. My car is S320 W220 1999.
