Overfilling the Coolant Reservoir

coolant

#1

Would overfilling the coolant reservoir way above the maximum line to the top, increase the pressure inside the radiator causing the radiator to spring a leak? I know this will cause the reservoir to spill fluid out but would it cause harm to the radiator?

No. Coolant reservoirs have overflow hoses specially designed to let excess coolant and pressure out, in order to prevent damage to the radiator or other hoses.
