Apart from peace of mind, here are some of the benefits of flushing your car’s radiator and cooling system:
Removes harmful deposits and scale
Sludge and particles are common in the radiator and hoses, and can lead to more serious engine problems. A flush will rinse these out, for optimum performance.

Lubrication
Replacing tired coolant/antifreeze with a new batch will lubricate moving parts in the cooling system, such as the water pump. This will extend the life of key components in the system.

Improved temperature and corrosion protection for the engine
Opt for a better-quality coolant/antifreeze following a flush, and you’ll better protect your engine from extreme temperatures and corrosion – helping with performance and improving its lifespan.

Knowing exactly what’s in your engine
If you buy a used car, it’s difficult to know what kind of coolant/antifreeze is in the system, its quality, and how often it’s been mixed with other fluids. Replacing old for new after a flush means you know exactly what’s in charge of protecting your Engine.
