A radiator that leaks, runs hot or needs frequent coolant top-ups can be wearing out. Before you replace it, look the radiator over with the engine off and cool. Coolant stains, cracked plastic tanks or bent fins can show whether the radiator or something else is behind the problem. Each vehicle takes one radiator.
