Why does the radiator cap not get hot?

The radiator cap will get hot if the coolant is near the cap. Caution should always be taken when removing it to avoid being burned. The maximum coolant level is below the cap, but the cap pressurizes the system. Removing it too quickly without allowing the pressure out can result in serious injury.


Where is the radiator cap on a 2002 Chrysler Sebring?

Try as you might to find it, there isn't one. Chrysler put the pressure cap on top of the plastic overflow tank! You need to make sure that cap has a good rubber seal on it when you remove it. [ you DO allow the engine to cool down before removing that cap don't you? ] When removing the cap, you should hear a short "hiss" sound which is pressure escaping from the cooling system (if the system is warm and not cold). Under these conditions, if there is no "hiss" you most likely have a bad cap so replace it! Only $4.80 at Auto Zone. Just do it. Good luck!
