When coolant needs changing

Coolant isn't just water: it contains glycol and corrosion inhibitors that protect the engine's aluminium components from corrosion. These inhibitors deplete over time, and after 4–6 years the fluid no longer protects the system — the water pump, radiator and even the cylinder head begin to corrode. Contaminated coolant shows as a brown or cloudy light-green colour. A chemical test strip (pH indicator) can quickly reveal whether the fluid is still alkaline (good) or acidic (change immediately). Manufacturers recommend changing either on a time basis (4 years) or mileage basis (60 000–100 000 km).

Why does coolant age?

The coolant's protective additives break down chemically with every cooling cycle. Heat loading and oxygen (which enters via the expansion tank vent) accelerate the decay. Mixing fluids from different manufacturers is the most common mistake: OAT and HOAT fluids aren't compatible and form a gel-like deposit that clogs the radiator's fine channels. Regular replacement with the right coolant keeps the system healthy for the car's entire life.
