ok, i can't seem to figure this one out. I turbo'd my d16y8 in my 98 civic. After I put the turbo in i found myoem radiator was leaking, so I puta new dual core fluidyne billet radiator in, new hoses, and a new thermostate. I am leaking coolant from the cooling system. It is coming from the oem overflow tank. The tank is filling up and leaking out, which in turnis causing the radiator to empty out eventually and make the car overheat. Now since the car is turbo'd, the coolant is running with much morepressure through the motor and I am thinking the overflow tank can't handle it. Do I need to get an overflow tank that is sealed on the lid unlike the oem one? Has anyone else had this problem? I just don't want to spend 100+ dollars on an aftermarket overflow tank to find out that it isn't going to help or the tank is going to explode under pressure or something. Anything would help. Thanks.
