Subaru Outback coolant reservoir boiling and smoke from under the hood after driving on Subaru Outback

Some Subaru Outback owners report experiencing issues with the coolant reservoir boiling and smoke coming from under the hood after driving. These problems may arise due to low coolant levels, which can indicate a leak in the system that could lead to overheating. Additionally, some owners find that issues with the water pump, thermostat, or air pockets in the cooling system contribute to these overheating symptoms. It is crucial for owners to check and top up the overflow tank with the engine cold, especially during the initial heat/cool cycles, to purge air from the system. Regular maintenance and monitoring coolant levels are essential for the proper functioning of the vehicle's cooling system.
