rb20 expansion tanks?

[xdream]

well ive been riding my rb for a while now with no expansion tank hooked up. i assumed that i never needed one with the rb for some reason. anyway i have a big intercooler and 3 inch radiator.

basically then one day during the summer my radiator started spraying water from the hole/valve that is suppose to go to the expansion tank.

now my question is how to i run a hose from my radiator to a expansion tank. my radiator doesnt have a male fitting for that. there is nothing to clamp the hose to.

also how are those metal coolant tanks because i sold my perfect plastic one.

you are talking about an overflow tank, expansion tanks are completely different.

what do you mean you dont have a nipple to attach a hose to, you just said water was spraying from it? have any pics?

it's a radiator overflow tank; you need to hook one up or other wise you will slowly draining your coolant
