FLAMINGO Radiator Flush (F037) Additive - 354ml

Got a car you want to keep running for a long time? Then a healthy cooling system is a must. Learn how to perform a radiator flush in five simple steps.

Vehicles need regular maintenance to keep working. While many of these maintenance tasks are small and simple, they can lead to big, expensive repairs if left undone for too long.

Flushing your car radiator is one of those regular maintenance tasks that every vehicle needs to keep working. The radiator is the heart of your vehicle’s cooling system, sending liquid coolant (coolant) to various parts of the engine to keep it from overheating. Fortunately, it’s an easy project you can do yourself.

Directions for Usage
