Overheating only when sitting still idling is almost always a problem with the fan.

And raise the level in the overflow bottle? That happened because the engine got hotter.


Brand new OEM battery last fall and new alternator in December

May want to start taking it to Krown rustproofing. If it stops the rust or slows it down a ton it will be worth it. Now would be the time before it's too late.
