Radiator: what it does & when to replace it
The radiator dissipates engine heat by cooling the circulating coolant. Failure signs include overheating, visible coolant leaks (often green, orange, or pink) under the car, low coolant level, or sludge in the cooling system. Plastic end-tanks can crack with age and the core can clog or corrode internally. Replacement is a moderate DIY job involving draining coolant, removing hoses and the fan/shroud, and properly refilling and bleeding air from the system. Always dispose of coolant responsibly, as it is toxic to people and animals.
DIY difficulty: Moderate DIY (drain + bleed coolant correctly). Always confirm the correct part for your exact build by VIN before buying.
