Collapsing upper radiator hose. boiling water when hot. can feel fluid boiling by thermostat housing
SOURCE: Overheating
it could be air lock , very common on those engines, more likley is a slight headgasket leak
SOURCE: 99 Chevy Silverado is overheating after maintance on radiator
check radiator, could b blocked, check hoses, mayb they soft, while vehicle running c if hoses r compressing, if they r would b iether radiator or hoses
SOURCE: just had water pump installed in 2001 impala,
water pump may not be sealed, have a look under the car for a few drips if it was the theromstat the pipes would expand not collapse. or maybe any water hose thats not sealed properly

Hi. A lot of work has been done with the engine. I guess all was left is the head gaskets. Try replacing the head gaskets. I provided you a link for better understanding. Please click here.

the low coolant light is a sensor on the side of the radiator with a wire plug to it you can disconnect it and the light will go out and youll be back to having to check the coolant level,as for overheating, tack the thermostat back and replace with another one, it will open in boiling water but is it open all the way and at what temperature, can effect your cooling did it have red dexcool in it before, might need to flush out the cooling system,this coolant will clog everything up and go back to the green coolant I dont know whos brainstorm it was for dexcool.......that stuff is no good
