It says LESS THAN 38ºC. 38ºC is not warm. It is cool. Warm is 50ºC. Your head should be hotter than the coolant, so it's over 100ºC when you turn your engine off after driving.

Alright so the ideal temp would be around normal weather temp ~25c.
Guess it wouldn't be a good idea to do it in Thredbo when its 2c lol
