A coolant outlet gasket may need replacing if you see coolant seepage or residue around the outlet, drips below that area, or a coolant level that drops between top-offs. If a failed gasket is causing the leak, this gasket replaces it. Clean both mating surfaces before you install it, and follow the vehicle service information for the correct fasteners and torque.
