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...
