Losing coolant

I think your radiator may have a leak. Where exactly is the coolant leaking from? From the overflow tube or somewhere else?

Did you make sure that the new cap is for the specific pressure in your vehicle? How often do you have to add coolant? Check the coolant reservoir for possible leaks. The cooling system may have excessive pressure due to a bad thermostat. Check the owner's manual to be sure of the where the normal operating temperature should be in the gauge, even if you think that the middle marker is correct.
