My car is a 62 nova with the 67' 230 engine. Today was the first time for me to drive the car so I have no prior history. I heard a rattle when I would accelerate a couple of times... sounded like something loose. A few min. later the the fan had tore into the radiator. The motor mounts are fine and the pump shaft seems ok... not loose at all and turns smooth. So how close should the fan be to the radiator on these L6's? I good reference might be the fan bolt heads to the core. Mine measures about .650" from the bolt head to the radiator. I beleive the fan is the stock type. Looks like to me the fan started hitting the upper and lower tanks... bent a blade tip or two...then the blades tips chewed into the radiator.
Maybe the water pump is the incorrect one? the engine came from a camaro but not sure if they had the same pump or if prior owner swapped it anyway.
Thanks, Clyde
