There are a few guys on the insight forum who made an engine blanket. WIth the cvts the engine still rolls and the water pump still pumps, so coasting to a stop the water temp does go down. Ive actually sat in traffic in the early mornings at idle with the heate ron and watched the water temp go from 180 to 137 and stay there til it picks up again.
Ive added water wetter to my cooling system too. I think this summer Ill drain it and use just water and water wetter so I can run more grill block.
