❓ Frequently Asked Questions
How much does water pump replacement cost in Australia?

What are the symptoms of a failing water pump?
Top 5 symptoms: 1) Coolant leaks (green/orange fluid under car), 2) Engine overheating (temperature gauge in red), 3) Whining noise from front of engine (bearing wear), 4) Steam from radiator, 5) Coolant reservoir emptying frequently. If you see these, stop driving immediately — engine damage follows.
How long does a water pump last?
Average lifespan: 100,000-150,000km or 7-10 years. Some last 200,000km+ if well maintained. Affected by: coolant quality (use OEM spec), driving conditions (stop-start traffic), engine heat cycles. Inspect at every service after 80,000km.
Should I replace water pump with timing belt?
Yes, always. The water pump is driven by the timing belt, so labor is shared. Adding water pump to timing belt job costs only $100-200 extra (parts), vs $400-600 if done separately later. Most mechanics recommend this combo. Also replace thermostat and coolant at the same time.
