Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hi. The coolant leak and the p0440 are not related. The codes indicate a problem with the fuel tank venting system. And the coolant leak could be from a hose, the thermostat housing, water pump, or radiator. The cooling system will have to be pressure tested to find the leak. The repair price varies depending on what component has failed. The check engine light is likely a leak in a valve on the rear of the fuel tank. That can run about 200-300 dollars to replace with diagnosis. Are you going to do any of the work yourself?
Ok then. Let me know if you have more questions on this. And also please rate my assistance using the 5 stars. Thank you.
