    I discovered this a few weeks back. Car runs fine, does not overheat at all. Fan cools it down quick from 210 to 200.

    I have replaced the cap thinking that could be the problem. Should I be concerned much or is it just poor china construction? Could be that I had filled the radiator too much?

    The first step is to confirm if the gauge is accurate by purchasing a laser digital point and shoot thermometer. If accurate, call the radiator company that made it or if unknown another manufacturer. See what they have to say.

    13lb vs 16lb should not make a difference. Champion builds their tanks to handle at least 16lb. However, because the tanks are fabricated out of a flat piece of stock, there is the ability for it to bulge a bit. If you notice the tanks like Cold Case and Griffin, they are stamped. In addition to looking more original, they are also much stronger when stamped.

    Well champion said it could have been caused by a faulty cap or clogged overflow hose. Have not checked the hose but have the new cap.

    This is possible. If either failed and your motor had an issue with overheating, the pressure could have built past 16lbs. However, I think you would have been able to see or feel a situation like that?

    I only had 1 incident where the motor got hot but not overheated. I had the bypass hose blow up and instantly pulled over....
