Chrysler T&C Engine Overheating: Active Air Flap Alert

Had the same issue on my 2007 Chrysler Pacifica last fall. The check engine light triggered due to a faulty grille shutter system. A diagnostic scan revealed fault codes related to the flap motor malfunction. The active air flaps were stuck in closed position, causing inadequate airflow to the radiator and engine overheating. The electromechanical actuator that controls these flaps had completely failed. This is a serious issue that needs proper attention since continuous overheating can damage engine components. Getting a diagnostic scan first makes sense, it will identify if the fault codes match the grille shutter system problems. The repair involved replacing the entire flap motor assembly and recalibrating the system. Job took about 4 hours at the shop. Would recommend finding a shop that specializes in Chrysler cooling systems. They should check both the mechanical components and electrical connections of the active air flap system. Regular cleaning and maintenance of the grille area can help prevent similar issues.

Thanks for sharing your experience. I had identical problems with my 2008 Town and Country thermal management system. The fault codes also pointed to the flap motor on my vehicle. Really interested to know what you ended up paying for the complete fix? My shop charged me quite a bit but wondering if that was standard. Also curious if youve had any car overheating issues since getting it repaired? Mine has been running perfectly cool for the past 8 months, but I keep a close eye on the temperature gauge now just in case.

Since getting the active air flap system repaired last fall, my Pacifica has maintained perfect operating temperatures. The repair cost came to 590€ for replacing the defective electromechanism that controls the grille shutters. This included parts, labor, and system recalibration. The thermal management system now works flawlessly, no more overheating issues or fault codes appearing. Like you, I still monitor the temperature gauge regularly, but mostly out of habit rather than concern. The flap motor and actuator assembly are functioning exactly as designed, helping regulate airflow to the engine as needed. Good preventive maintenance is keeping the grille area clean and free of debris that could affect the shutter mechanism. This helps avoid future problems with the active air flap system. The investment in proper repairs by a qualified shop was definitely worth it for long-term reliability.

Taking your initial car overheating problem to a certified Chrysler mechanic turned out to be the right choice. The diagnostic scan confirmed my suspicions about the grille shutter system failing. Shop charged 780€ total, bit steep but the thorough repair was worth every cent. The mechanic discovered the active air flap mechanism was completely seized up from debris buildup, blocking proper airflow to the engine. They replaced the entire assembly and recalibrated the thermal management system. Really impressed with their detailed explanation of the issue and prevention tips. Since the repair 8 months ago, engine temperature stays perfectly normal and check engine light hasnt returned. Still monitor the gauge occasionally but mainly just keep the air intake area clean now. Glad I found the right shop to properly diagnose and fix it instead of continuing to guess at the problem.
