I should have scripted this message better. Sorry for the confusion, but the
act of adding the coolant by my wife was knee-jerk and only bloated the
resevior; I've held steady coolant levels all summer long, although now I
need to drain out the excess.

Since the low speed fan never kicked in as the needle approached the led I
think it's the fan switch. I'm going to try the test Ken Wilford has
outlined (How-To Test your fan setup) and hopefully the overheating is only
a fan thing!.

Thanks,
Dan Haydon

on the AC and the high speed fan kicked in.
