Reply to "Too cool?"

Sounds like I may be too late since you've already ordered it, but I would go with the 192F, especially since you live in Denmark. I have a Robert Shaw 192 thermostat and I have no problems with overheating despite living in Spain! Perhaps in extreme conditions you might want a little more margin with a 180F, but you shouldn't experience that. I prefer the warmer temp for reasons Dan mentions, and I've read that the engine is "happier" and makes more power a little warmer.

With respect to your first post, the only odd thing is how long it took for your coolant to warm up. I am amazed at how quickly the coolant reaches operating temperature in my car. In probably 3-4 minutes I am at 192, where it stays. I'm guessing that your car takes so long to warm up because you've got the Windsor thermostat, which allows part of the coolant to circulate.
