Customer Question
Engine fan won't turn...

Engine fan won't turn off. 1994 Pete 379 with 6nz cat has a Horton fan clutch

Mechanic's Assistant: Is this an aftermarket fan or did it come with the vehicle? Do other devices still turn off normally?

This truck had a Detroit 60 series in it but I pulled it out and put a cat in it

Mechanic's Assistant: What's the make, model, and year of your truck?

1997 Peterbilt 379

Mechanic's Assistant: Is there anything else the truck Mechanic should know before I connect you? Rest assured that they'll be able to help you.

Need to know how the fan clutch relay is wired ?

Can you provide the last 6 of the VIN please? I'll pull a Peterbilt schematic for the Detroit engine and then I'll find another Peterbilt schematic for a Cat and send them to you.
