My 2012 Dodge Journey overheated yesterday just as I was getting close to home. I had topped off the coolant earlier in the day as I knew I had a minor leak and the temperature gauge was getting high. The car was driving fine for 30 minutes after that and then got hot pretty quickly.

This morning I opened my radiator cap and did a cold start. I let the car heat up. I didn't see any bubbling in the radiator. There is no milky substance on the oil cap or dipstick and no white smoke coming out of the exhaust.

What is happening is that the engine light is on and the car isn't blowing hot air even with the heat on.

Coolant levels look ok.

Just wondering if my problem might be the leak getting worse than I thought, a faulty radiator cap or is it something else?

Thank you
