Overheating Issues!

I had an problem like this. Driving easy it was fine, at 65 mph plus it would run too hot. A brand new radiator solved the problem.

Mine was the same way, used to be fine and then one day the motor started to run hotter. Radiators do not last forever.

Its going to cost you more than $100 I am afraid. A shroud might help too, they really do but how come you had no problem a while back running no shroud / maybe cause the radiator was working better back then. Radiator exchange heat, clogged rads do not.
