I tore up the front end in a wreck. The body man that replaced my front clip could not remember how to plumb the radiator and I never knew. I've got 7 holes in my new radiator. Fill, upper hose, lower hose, vent bottle, and two trans coolers. What is number 7 for? It is located above the two trans cooler holes. My Haynes and Chilton books don't provide a plumbing diagram. Thanks for your help, I know this is going to be easy, huh!
