This engine came out of what again, an Accord? TSX - same thing, essentially. A car which weighs literally twice what the K-sight does, and has poorer aero to boot. No wonder the engine runs cool.

I wonder if you even need the radiator fan.
I'm running the stock 1.0L radiator, which I believe is half the size of the TSX rad. On a warm day if I'm idling, the fan does cycle. Driving, never.

Typical driving the TPS usually reads 3-5% even with my tall gearing.
