What is a car radiator and why are they important?
The radiator is a key part of a vehicle's cooling system. Radiators are designed to stop the engine from overheating.
As your vehicle's engine runs, it burns fuel to power your vehicle and produces a significant amount of heat. If the temperature of your engine rises above a certain point, it can cause damage that can lead to your vehicle requiring costly repairs.
Other parts of the engine's cooling system include a liquid coolant, circulation hoses, a fan, and a thermostat that monitors the coolant temperature. The coolant travels through the hoses from the radiator, through the engine to absorb excess engine heat, and back to the radiator.
The most common reason for a vehicle to overheat is a leak in the engine coolant reservoir. The cooling system pumps a coolant fluid through pipes surrounding your engine's cylinders. The liquid coolant (also known as antifreeze) reservoir is a vital component of the cooling system, as it stores excess coolant fluid until required. A reservoir can be located by following the hose extension from the radiator. An overheating engine can build pressure within the radiator and can cause serious damage if left unchecked.
There are many potential issues that can cause overheating including cooling fan malfunction, a damaged heat exchanger, a damaged drain cock, a malfunctioning intercooler junction, or an uncleaned radiator grille shutter.
