Why should I change my coolant?

Engine coolant is one of the most important fluids in your vehicle, working tirelessly to keep the engine cool and performing optimally. Its primary function is to absorb and dissipate the heat generated by the engine, circulating through the engine to maintain a consistent temperature throughout.

This vital fluid typically consists of a mixture of water and glycol, as well as various additives that prevent corrosion, lubricate the water pump, and maintain a stable pH level. The glycol component not only lowers the freezing point of the coolant but also raises its boiling point, ensuring that it remains effective in extreme temperatures.

However, engine coolant can break down over time due to exposure to heat, oxygen, and contaminants, becoming less effective at absorbing and dissipating heat. This can lead to engine overheating, reduced performance, and potential engine damage. This is why it is crucial to change the engine coolant at regular intervals, as recommended by the manufacturer.

Failure to change the coolant can have dire consequences, such as the corrosion and deterioration of rubber hoses, which can result in leaks and engine overheating. Old coolant can also corrode other metal components in the engine, such as the water pump, radiator, and heater core, leading to reduced performance and increased risk of engine damage.

Regularly changing the engine coolant helps to prevent the build up of corrosive by products, protecting engine components from damage, and ensuring that the engine remains cool and performs optimally. To keep your engine running smoothly, it is recommended to change the coolant every two to three years or as recommended by the manufacturer. The most common cause of coolant leaks we see in house are due to cracked and hardened hoses or rock solid gaskets. Don’t overlook the importance of this vital fluid, and ensure that your engine remains cool and performs at its best by regularly changing the coolant.
