I don't use a pressurized cap, same as the cars, and I don't recall seeing anyone use one. Larry----- Original Message -----

Jeff,I have an overflow, outlet in the neck of the radiator. So far I always get some blowing over of some water at full power. I think it is a function of the water pump throwing the water up there. I restricted the fitting down real small and that helped. I need to also create some kind of labyrinth to lesson the amount. Dan HelsperPuryear, TN-----Original Message-----
