❓ Frequently Asked Questions
How much does timing belt replacement cost in Australia?
Average cost: $500-$1200 AUD. Parts: $150-$400 (belt + tensioner + water pump). Labor: $350-$800 (3-5 hours). Economy (Mazda 3, i30): $500-700. Mid-range (Camry, RAV4): $700-1000. Luxury (BMW, Audi): $1000-1500. Always replace water pump at same time ($100-200 extra parts).
When should I replace my timing belt?
Replace at 100,000km or 5 years, whichever comes first. Some manufacturers say 150,000km, but 100k is safer. WARNING: If timing belt snaps, engine is destroyed ($3000-$6000 rebuild). Never exceed the replacement interval. Check owner's manual for exact schedule.
What happens if timing belt breaks?
Catastrophic engine failure. The pistons hit the valves (interference engine), bending valves and damaging pistons. Repair cost: $3000-$6000 (engine rebuild) or $5000-$8000 (engine replacement). This is why timing belt replacement is critical — a $700 service prevents a $5000 disaster.
Should I replace water pump with timing belt?
Yes, strongly recommended. Water pump is behind the timing belt, so labor is already paid for. Adding water pump replacement costs only $100-200 extra (parts), vs $400-600 if done separately later. Most mechanics include this as standard. Also replace tensioner and idler pulleys.
