One of the best tools I have. Fill the system then place this on where the radiator cap goes and pump
up the pressure forcing the water into the places it usually doesn't reach with grvity. Then take it off, refill and repeat until it wont take another drop.
After that get one of these...

After you go for a spirited drive stop the engine and check the enrty hose temp and the exit hose temp. This will tell you exactly what temp your motor is running at.
