Enclave Engine Cooling Issues Signal Warning Signs

Having dealt with similar cooling system issues on my 2020 Buick Envision, I can share my experience as someone with some automotive repair knowledge. The symptoms you describe match what I encountered. After checking the engine cooling components, it turned out the issue was surprisingly simple, a blown fuse that controlled the cooling fan circuit. The restricted airflow through the cooling grille was actually due to the fan not operating properly because of this faulty fuse. The repair was straightforward and cost about 52 Euro including diagnostic time. The workshop identified the defective fuse, replaced it, and verified the cooling system was functioning correctly. Before jumping to major repairs, you should check: Coolant level and condition, Radiator fan operation, Fuses related to the cooling system, Any visible blockages in the automotive cooling components Could you share some additional details to help diagnose the issue: Are you hearing the cooling fan running? When did the check engine light first appear? Have you noticed any coolant leaks? Does the temperature fluctuate or stay consistently high?

Thanks for the input. My vehicle has 103805 KM on the odometer, just had its latest service about 2 weeks ago. The cooling fan appears to be operating, but I noticed some debris buildup around the radiator grille area. After inspecting more closely, there does seem to be significant blockage affecting the airflow through the cooling system components. The check engine light came on just yesterday, and I have not spotted any coolant leaks so far. Temperature readings are consistently high rather than fluctuating. Will try cleaning the grille area thoroughly first to improve the automotive cooling performance before looking into other potential issues.

Good to hear back from you. Based on the debris buildup you mentioned, cleaning the radiator grille and surrounding area is definitely a smart first step. When I dealt with thermal management issues on my Envision, I also discovered leaves and road debris restricting airflow through the cooling components. The consistently high temperature readings combined with no visible coolant leaks suggests radiator blockage rather than a more serious cooling system problem. Since your cooling fan is working properly, unlike my faulty fuse situation, focusing on clearing any obstructions should help restore proper airflow and cooling performance. A few specific suggestions from my experience with radiator maintenance: Use compressed air to clear debris from both sides of the grille, Check the area between the air conditioning condenser and radiator, Verify all mounting points are secure with no loose components, Inspect the radiator fins for damage while cleaning Let us know if cleaning the automotive cooling components resolves the temperature and check engine light issues. If problems persist, we can explore other potential causes.

Thanks everyone for the helpful suggestions. After following the cleaning recommendations, I can report some positive results. The thorough cleaning of the radiator grille and surrounding areas has made a noticeable difference in the engine cooling performance. The temperature readings have started to normalize, though the check engine light is still on. Used compressed air as suggested to clear out all the debris, and was surprised by how much material had accumulated between the condenser and radiator. The thermal management system seems to be functioning much better now with the improved airflow. All mounting points were secure when checked, and the radiator fins looked intact, just dirty. Will monitor the situation for a few more days to ensure the automotive cooling system continues working properly. If the check engine light persists after the cleaning, I may still need professional diagnostics to rule out any other issues. But for now, the simple maintenance approach seems to have addressed the main concerns with the overheating symptoms.
