Help with Cooling Issue Please

Can't say this enough, but be sure that there is NO AIR in the system. Found that was the problem with mine, and I went thru the parts trying to cure it. The reason I figured it out was the guy down the road has a 500" motor with a small radiator and a small 16" fan. He never gets hot, and figured it must be something basic. Found a post about raising the front of the car up and running the car with the cap open. Did this for a few hours (electric water pump), and I went from 190 to 210 degrees to barely having the electric fans come on at all. Couldn't believe it was that darn simple....Be sure the air is out of the cooling system.
