i swapped a 00 si into my 99 ex, everything was going fine and for the most part still is. the only 2 problems i had was when it snowed one day i was driving the car and i saw that smoke was commin from under the hood, it looked like it was commin from the radiator or in that area. i loosened the hose clamp a slight bit and after drivin around a little bit it stopped, and i never figured out what was wrong. now my temp needle seems to be holding in the little bit over half way mark on warmer days but not by a lot and it stays at half way point on cold days. do i need a new radiator to run this swap? or am i just being paranoid? and if i do what is a good radiator that has oe fitments and can use all the same hoses and fans
