hey guys,

i got a H22a in my civic and was using a prelude radiator but i changed it over to a KOYO aluminium radiator and ever since then i have had problems.

My car is running exactly 10 degrees hotter no matter whether on the highway or in traffic, it runs at 98 degrees . Also once the car has heated up it is pushing coolant into the overflow.

i have installed a switch so i can control my radiator fan in cabin or so i can run it constantly once the car has warmed up( i run the fan constantly once the car is warmed). i have also purchased a cusco 1.3bar radiator cap. i have flushed and bled the system.

i just cant seems to get the temperature any lower. i want to get the temp back to around the 85-88 degree mark where it used to be.

obviously it has something to do with the radiator as i had no problems before i changed them.

anyone got any ideas or suggestions.
