Installed new Edelbrock 8843 Victor series water pump on my SA 396W. Drained off 11 qts fluid before and put 12 qts back. Warmed up to 180 degrees and thermostat opened and temp dropped and then started back up. Drove around block and temp went up to 220. When stopped it went to 250. Turned off motor could hear water boiling in top of head. Top radiator hose very hot while bottom very cool. Let engine cool down and checked water level, only took 1 cup of fluid. Bleed off fluid at temp sensor behind thermostat. 2 days later it did the same thing. Replaced thermostat and did the exact same thing. It's like the pump doesn't have an impellor in it or it has a counterclockwise and my motor is a clockwise. Any body have any suggestions?
