The vehicles mentioned above may experience clattering noise coming from the engine compartment. If this happens, special attention should be paid to the lines of the air-conditioning system.
There is a possibility that the noise may be caused by insufficient clearance between the refrigerant line and coolant expansion tank.
This can be fixed by installing a modified refrigerant line and/or installing the line correctly.
