hi all. i just replaced my engine and i bled the radiator and got all the air bubbles out. the problem that i am having is that the radiator is not building up pressure. there are no leaks that i can see and there is no white smoke coming from the exaust and no small bubbles coming from the radiator fill hole ruling out the head gasket. i dont know what is wrong. someone please help. thanks so much.

 

What do you mean? Is it not holding pressure, or is it not heating up? Did you install a new or used motor?

 

water pump?
