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

 

99 y8 to 00 b16a2 should require an immeadiate radiator upgrade... if I were you I'd do a flush and fill and just monitor it...

 

edit. nevermind

 

another problem i had in the begining was the coolant was draining real quick, i was filling it about every3 days

 

Are you sure your not leaking collant anywhere?

 

yeah, i park the car in the garage and the floor is spotless

 

Find a shop that has a radiator compression tester and put it under pressure. There has to be a leak somewhere, external or internal. Hopefully it is external. If it is loosing pressure and no external leak, good luck...
