If you are spewing (dumping) coolant it could be that you are overfilling the header bottle. The origional plastic one allowed you to see the level and it has marks indicating low and high. When you use the metal one you can no longer can see the level and it does not have any markings indicating low and high. When the motor is cold (and that is the only time you can safely remove the pressure cap and see the level) the tank should be around 1/3 to 1/2 full. Fill with a 50/50 mixture of soft water and permanant type ethelyne glycol anti-freeze (summer or winter). Never run on only water except to test for leaks. Of course you will dump coolant if you overheat no matter what you do with the level when cold. If the fans don't come on before the temp gets too high then you could have a bad otterstadt switch and maybe the circuit breaker should be changed. You can always turn on the A/C, that should cause the fans to run.
