    Recommended Radiator.

    So car's been overheating lately.. Runs cool the majority of the time except on interstate.

    At first it was pretty bad cause once it started overheating it didn't stop getting hotter, until i turned the car off and let the car cool down.

    so then I hardwired my fans, changed the thermostat. so now it stays cool as long as i stay off the interstate. even when i drive it really hard it stays cool. doesn't make sense....but it doesn't overheat near as much when it does overheat, it just goes a few marks over where it normally goes. so doesn't do it too bad, and it usually ends up going back down.

    I also did a full Radiator Flush running a 50\50 mix, and i have a brand new water pump.

    anyways I've come to the conclusion my radiator is probably time to get the boot.

    So here's my options.

    1: Rebuild radiator... I know a shop that does it really good, and this is the cheapest.
    2: Junkyard radiator
    3: Stock Replacement
    4: Aftermarket Replacement.

    Obviously 4 is my choice so my question is..

    I want a direct fit all aluminum radiator. which would you guys recommend? I do alot of daily driving, but at the same time alot of spirited just cause driving, and I do track days (road course not Drag) so what would you recommend I want Direct fit, not universal. also would you recommend aftermarket fans or do you think the stock ones will do for now?

    2" Koyo or the 3sx dual pass.

    I have the 2" Koyo and it keeps my car incredibly cool

    I like my mishimoto with 2 passenger side stock fans (not necessary). But you have to modify the stock brackets or use the 3sx brackets. The dual pass you need to chop your upper coolant hose. Not sure if the koyo requires those brackets or not, I think the 3sx single pass comes with them already.

    Have you cleaned the fins on your stock radiator? I used a power washer on mine and it stopped overheating. Actually stays solid and cool now in the TX heat. The stock radiator is not that bad + we have excellent fans.

    Be careful with a power washer if the radiator is looking rough. I took a regular hose to the one in my nissan pathfinder and it immediately blew the fins right off.

    sounds like Koyo or 3SX single pass.

    I suppose the 3SX is the only one that directly drops in and doesn't need any modification or has everything you need to make it work?
