Well i have been noticing latley, when i half throttle it at around 50 F weather, that my coolent gauge gets colder by just a little. Does anyone think thats wierd? my brother said, "It's just the coolent swishing back an forth", but for some reason i can't buy that, Garret @ worldone said it's prolly just because its cold.

What do yall think?

 

I'm not positive...but I think the water pump's speed is dependant on the RPMs. So if you give it more throttle, you get a higher flow rate of coolant though the engine. That means the coolant goes through the radiator at a higher rate, and since it's cold enough where you are to cool the coolant even though it's spending less time in the radiator, you end up with cooler coolant. Maybe...
