Need a little advice, please

[306bullet]

1. Factory clutch fan
2. Original Radiator.........w/ 50k mile (the tubes which are visible through the filler neck, are clean)
3. It will continually climb, as long as I run the car (even though it is very slow to climb)
4. After my original post, I installed a 160. Not much of a difference, if any?


If my car is running hot, why would I put a warmer t-stat in? I can tell that the stat is opening. It opens right around the 160-170 degree mark on my gauge (seems to be more accurate than some that I have run in previous cars).

I have heard people talk about sizing a radiator "by horsepower" before. I don't know if this is true or not? It just seems as if the car wants to stay cool, but evenutally the radiator just can't keep up?

P.S. The car itself only has 50k miles on it. It is ultra clean, as was the drivetrain. The fan and radiator all look to be in good working order, otherwise I would have replaced them.
