Hi guys i had to put a new radiator in my mustang, and it doesnt seem to be working right because it gets way hot, and i have to shut it down. I have enough coolant in there i think?? When it gets hot it goes into the overflow tank. I bought the radiator from teamradiator.com. There are a couple of rubber plugs that can be screwed in on the side, which didnt exist on the factory radiator.. I screwed them in tight by hand??? What is going on here? Please help!
