My car, for the last couple weeks, has been running consitantly at 103*c and coolant has been flushing into the overflow...and disappearing elsewhere like mad. Having succomb to BHG a mere 8000 miles ago I obviously feared the worse. But I went ahead and took a shot in the dark and threw on a new radiator cap. Worked wonders. Car now runs consitantly at 90-95*c and coolant no longer disapears. Replacing the two deteriorated hoses leaking profusely probably helped too.
