From what I have read the overall coolant temp will be slightly higher due to the lower cooling ability of the fluid. The main advantage though is the much higher boiling point of 180c. With this comes much less pressure so it's much easier on the engine. Reading a blog from someone with a k series powered lotus the running temp increased by 3-4c

They state that with normal water based coolant the rad will be slightly cooler but you get steam / boiling occurring inside the head at certain hot points which this fluid eliminates - less chance of head damage.

What are your thoughts on that claim Cliff?
