Also verify that the visco clutch is working, and that the aux fan comes on, although you should also be running rather warm to get coolant loss out of a good cap.

Hi Psfred,
I have a 260E, 1988 euro, I have the feeling that mine is engaging at higher temperature than it should.
Do you know how to check the visco clutch
Thanks in advance
