I know this may sound silly but when I had my degree key put in by Honda they said I was low on coolant, even though my fluid level showed ok prior. My fan came on all the time, and now it only comes on for a couple minutes when I run hard.

Anyway they said when they drained my machine they barely got a quart of coolant out and it should of had 2 1/2. They were claming there was something wrong with the level in the coolant tank versus the amount of actual coolant.
I just blew them off at first, and was thinking that the advance of the timing cooled me off.
That makes no since at all, you advance timing you should fire more and run hotter.
Now I read about all these high temp problems and I wonder.
