I can't get into many details because I signed a document not to disclose much info. Take it out and report back
There are a few reasons why he would over heat.

1. There isn't any air moving throw the radiator
2. Coolant is leaking out somewhere AKA head gasket
3. Coolant isn't moving AKA waterpump impellers

I suggest that you test the fan clutch first then the oil for coolant. OP it takes 2 seconds to do these tasks. Try them and get back to us
