Worked on diagnosing and fixing the oil cooler fan not coming on over the weekend... Image Unavailable, Please Login
Then I pulled the relay, checked all signals to the relay connector terminals, 12V from Battery, GND, 12V from ignition coil to energize relay... all checked out. Image Unavailable, Please Login
Benched checked the relay. It closes when the coil is energized by 12V, however, could not carry the current to run the fan. Bad, dirty contacts.
Is the plastic replacement a Bosch Brand as well . If it’s Bosch , what’s the Bosch part no. It’s usually stamped on the top . Thanks in advance , Luigi
