Impala owners - suggestions - LT1 BUICK

I have a 95 Roadmaster, 100k miles. In an attempt to cure an overheating problem, I have pulled off and inspected the water pump and rad. Now it's ready to go back. I was thinking since I have all this stuff off, is there anything else that needs to be inspected at this time before I go back with the pump and rad?

Thanks Guys

flush the engine coolant passages, replace the hoses and thermostat...
