I see, thanks.

The Engine Control Module (ECM) controls the level of engagement of the electronically controlled viscous fan clutch by monitoring coolant temperature, intake manifold temperature, air conditioning pressure and transmission oil temperature. Based on cooling requirements, the ECM sends a signal to the viscous fan clutch to increase or decrease the fan speed.

.

I can put the description of it and the wiring diagram in a PDF file, (it is rather large) and send it to your email address for as little as is allowed.

.

You will just have to accept the additional service offer and ENTER your email address in the private section so that I can see it. I do not have access to your email address, Thanks

Jerry, I found the specs online 12v @pin 5 and 5v on pin 6 to activate clutch. My clutch appears to be bad.
Expert:  Jerry replied 1 year ago.

That should actually be 12v on pin 6, (pink/yellow) and 5v on pin 5 and the coil signal, (pin 1) .

If that's the case, I would have to email you the PDF file with the instructions for replacing the fan clutch. The file is rather large, thanks
