Hi steve. I have a 2011 cxu 613 Mac and the engine blew out in it. So I bought a used engine and have many of my parts from my old engine installed on it but now the engine fan does not cut on with the newer engine install.

Mechanic's Assistant: What's the make/model/year of your truck? Engine type?

MP8

Mechanic's Assistant: Anything else you want the Truck Mechanic to know before I connect you?

Yes, the mechanic said when they unhooked it from the engine or the computer from the engine the fan cut on but then when they connected back to the computer it does not work

On your question, I would first check the engine for any fault codes. Make sure there is none for the fan solenoid or fan driver. If that is okay then I would run the fan override test. This will test the fan driver to make sure the ecm is working fine. If it does not then I would examine the wiring leading up to the engine interface connector to make sure no wires are pinched or broken from being disturbed when the engine was removed or installed. I hope this helps you with your question. Thank you
