My tempture guage ?
My car E240, am learning about this car. 2000 E240s have an electric radiator cooling fan behind the radiator. No clutch drive fans on these cars. No aux fans in front of the radiator on this car.*
Much like others on this thread, I noticed the following about the engine temperature:
- While moving in town or on the highway, AC off: ~85-87 degC exactly.
- Idling / stuck in traffic, AC off: ~95-97 degC. Cooling fan runs, but the fan speed seems very slow - like 2 revs per second. If I turn on the AC, fan runs higher, but I wouldn't say that it's fast; engine temp stays at 95deg C. Ambeint temps are around 70F - very mild.*
I don't particularly like it idling at 95-97 deg C on such a mild day (what happens when it gets 110F here stuck in traffic, as it does sometimes....) I found another post on thermostats which shows photos of instruments at highway speed and at idle, all right at 85deg C, consistently. My toyotas only vary over maybe a 3 or 4 degree span, not 10-12 degC span.*
I changed the thermostat - identical behavior - no change.*
Question: how do I CONFIRM whether the fan is running at the right speed? Many vague posts, but there must be a way to test voltage vs. speed or voltage into a regulator vs. voltage to fan or something?*
Any advice would be most welcome - Thanks!
