Default Cooling/Radiator question on 85

When my 85 is cold,the coolant level in rad is about 5 inches from the top.Overflow is full.

At idle( after warm up) the tmpwill go to 195-200.At hwy speed ,the temo stays 180-185. I run a 180 stat with a new 15 lb cap.

Is this normal or is my water pump on the dump?

Thanks

The only problem *I* see is that you need to fill the radiator. Temps are good. Why the concern over the water pump?

RACE ON!!!

I recommend emptying the overflow to start with. The resevoir Being so low in the car the gravity will actually pull it from the radiator. Check all the clamps are tight. Find a steep hill, and park the car nose up, and fill it. warmed up all the way start the car and rev it to~1700 rpm then top it off, and close the cap while holding the rpm's up(you may ask someone for help). Let it cool like this, still parked on the hill nose up. Then pour about 12 oz. of coolant in the overflow.

I'm not saying this will fix any car but it did mine.
