    Hello I just bought a CRX Si and it has a manual radiator fan switch. Do I only need to turn it on when I see my temperature rising above normal or should I be running it all the time?

    Ok thanks alot. Yes I know it is not OEM. The previous owner did a whole bunch of weird crap but it was cheap and a good base start so I thought I would buy. Thanks again.

    yeah when i put a new radiator in my REX i had that switch run because i didnt know where to plug the wires into to switch on automatically. you'll loose performance if you run the fan constantly so your better off getting someone to rerun it to click on automatically at the right temp unless you dont mind hitting the switch when you start to over heat.
