I know I've asked variations of this question before, but I can never really get straight what appropriate running temps are. I have an OM603 with what I assume is the #14, so I worry very much about a cracked head:
Today it was about 85F ambient temperature as I was driving to work. The drive is a bit uphill but hardly a mountain, and it has three or four stoplights, which are ALWAYS red when I get to them. Toward my destination I noticed the engine temp reached almost 100 and stayed there ... I stopped for a coffee, when I started up again it went right back up to 98 or so. I let it idle for a while when I got to work an it dropped a couple degrees, maybe.
This car usually runs at about 85, 80 when its cooler outside. It does go up to 100 pretty much everytime I drive up Nittany Mountains (about once every two months), but that's a big mountain and I expect it.

Is it normal for my car to get so hot on a normal, slightly uphill drive when it's 85-90F outside?

Again, sorry to be repetative in my question-asking ...
