The only thing that come,s to mind is radiator,need,s rodding out or replacing.


Yeah I'm gonna try that next and see what happens


1} What was the original problem that prompted you to replace the above items? Over heating shouldn't be happening at highway. If it does try this, turn on your heater. If your temp starts to go down or at least stop rising then your radiator is clogged. Blower fan needs to be on high.
