Radiators

Im useing the original water pump that came on the motor in 71...LOL
but for a fan I had been using a 7 blade aluminum flex fan with out a shroud and it worked perfectly ...so why did I change it? Well for one it sounded like a tornado and two when sitting at stoplights in a school zone it would suck little kids into my grill...LOL Do you know what a pain it is to get out and scrap 2nd graders off your grill?now I'm using a electric fan off of my wifes hyundai, it only about 10-12 inches in diameter and mounted offset to the side ...seems to work just fine but for safety I am putting on a bigger one in a few weeks
