The radiator dissipates heat from the engine coolant to the atmosphere, preventing overheating. Modern radiators use aluminium cores with plastic end tanks for lightweight efficiency. Leaks, internal blockage, and physical damage from road debris are the most common failure modes. A failing radiator causes overheating, which can lead to head gasket failure and catastrophic engine damage if not addressed.
Radiators don't have a fixed service interval — they fail from corrosion, impact damage, or age-related degradation of the plastic end tanks.
Replacement radiators are available in OE-specification and aftermarket options. Ensure the core dimensions, hose positions, and mounting points match your vehicle.
