Which one is the B10/8 coolant temp sensor? (W140)
 

I did a search on this subject, and didnot find anything specific to the 600. I want to incorporate Jim F's technique to turn the auxilliary fans on at a lower engine temperature. I removed the left front engine cover on my V12, and saw three sensors. One of them looks exactly like the B10/8 sensor on Jim's web page. But according to Alldata, what I thought was B10/8 is not. See photo...

Are there any Master Mech's out there that can tell me which one is the "real" B10/8?

By the way, here's the link to JimF's great web page...

The coolant temperature sensor that controls the aux fans (B10/8) is the blue one on the right. The one on the left (B13) is the sensor for the temp gauge.

Just saw this post . . .
 

so I'm about a year too late!! But that IS the B10/8 sensor despite what AllData says.

Anyway the picture is very nice; first one I've seen for a S600.

You're not late Jim. You responded to a private e-mail I sent you. Thanks.
