One thing many owners overlook, and are unaware of, is clogging of the
radiator from that nasty Cottonwood Tree Fuzz.
If you live in an area that have these trees, it is wise once a year, to
pop the top Radiator Shroud, and take a peek down there in between the
Radiator, and Condenser.
I've had this happen to a couple of vehicles, Literally looks like
Fiberglass Blanket Insulation.
It will cause your temps to climb quite a bit. Mark
