Re: Cooling question
Make sure you don't have this problem; hot air recirculation. Some radiator installations allow air from the hot side of the radiator to flow back around to the cool side, and be heated further. This continues, and the system gets hotter and hotter. Recirculation is usually more a problem on parked cars, or at low speed, as the forward motion does not create enough air flow. For that reason newer cars have this plastic cover under the engine. Another issue some people argue is, excessive water flow, which didn't let the water do its job of extracting the heat from the engine block.
"Peter Bryant,the designer of the Shadow Can-Am and Formula cars states in one of his books that they kept putting biggger and bigger radiators on the first Shadow Can-Am car and all that was wrong was that the water pump was moving the water to fast and it did not stay in the radiators long enough to cool." Although a low water flow can adversely affect cooling system too.
