Cooling issue on highway
Every modern car including the 6.4 Mopars have run nothing but electric fans for more than 30 years. Millions on the road with no problems.
Problems always start when homegrown engineers think they know more than the companies that have invested millions of dollars in engineering and testing the systems. They have to warranty the drivelines for up o 100,000 miles so they have a vested intertest in there being minimal problems.
Factory stuff works, why always trying to reinvent the wheel...
