Hello all, My 2010 3.7 overheats at idle. Reads halfway at highway speeds but after 7 minutes idling its up around 3/4. I had error codes that read misfire 3 and misfire cyl 4. Replaced all spark plugs with iridium, wires, coils and fuel injectors for those particular cylinders thinking it could be firing or timing related. Whether I turn the heat on, or AC. it makes no difference. What's you experience??? Thermostat next then the radiator? Not a pleasant idea Thanks in advance... |

1st put copper core plugs back in,iridium plugs are bad for your engine. Overheating at idle but not at highway speeds means a coolant flow/airflow issue like a bad waterpump,junk blocking the radiator,or a bad cooling fan.Common to get crap built up between the AC condenser and the radiator if you venture offroad in mud and such. |

This happened to me last year and ended up being auxiliary radiator fan died. When I was driving highway speeds, the 70mph+ winds swept the heat off the radiator, but when stopped, the heat just built up. Not sure if this is your issue though, because when I turned my heat on full blast, the engine overheating slowly went back to normal. |
