And THAT my good Woman is why I think it's a flow problem.
The coolant may be staying in the radiator long enough to get that cool instead of circulating it through the engine faster.
That is good info inertia, thank you.
Never occurred to me to check it that way, but sometimes the vanes are mostly gone from corrosion too, so it may not be a for sure factor.
Water pumps are so easy to pull it might be worth it.
