Weak hoses....may need to build a spring insert to go into the hoses or modify with aluminum or copper tubing.
Might also have a partial obstruction in radiator

Just a shot in the dark here. I don't know what year, but later models w/serpentine belt used a reverse rotation water pump. If you reused same pump, disregard this. I've had an air pocket do this also.
