Common Symptoms in the Audi A4

Coolant looks rusty or brown

Reached manufacturer interval (60,000 to 100,000 miles)

Heater not putting out much heat

Engine running slightly hot

What It Is

Coolant absorbs heat from the engine and dumps it through the radiator. The corrosion inhibitors in coolant break down over time.

Why It Matters

Old coolant becomes corrosive and damages the radiator, water pump, and heater core, all expensive parts.
