Unfortunately, I don't have a coolant thermos. That's an '04 and up luxury. I'll test it anyhow for what it's worth.

It makes a big difference on my Previa. Similar wattage (400) but it's in a better location under the engine. The Prius location is not the best as it's flat on the side of the block and must lose more of it's heat to the outside air than if it were embedded straight in. Makes me want to insulate that side of it but how, I don't know yet.

The difference in my commute between a warm and cold engine is dramatic though.

I think Bob has tested his but he's in a warmer location. My coolant was -3C/26F this
morning.

I'm going to work on some other warming ideas as well. like a transaxle warmer and engine oil pan warmer.
