Not the hose from the reservoir to the radiator for sure.
Yknow...it is entirely possible, as embarrassed as I am to say, that it
could have been a spill. It's killer windy here in the midwest right now--perhaps I spilled more than I thought.
Will check it again after the commute and if need be--use a funnel! (Eek. I'm not a blonde--really!)
If I find it was a spill, I promise no more questions here without more thorough research!
