Radiator Repairs in Artarmon — Keep Your Engine Cool

An overheating engine is one of the most serious mechanical emergencies a driver can face. Continued driving with a hot engine causes warped cylinder heads, damaged head gaskets and potentially complete engine failure. At Brumby Motors in Artarmon, we diagnose and repair cooling system faults quickly and accurately — whether it’s a simple coolant top-up or a full radiator or water pump replacement.

Signs Your Cooling System Needs Attention

• Temperature gauge climbing higher than normal — act immediately
• Coolant warning light on the dashboard
• Steam or smoke from under the bonnet
• Coolant level dropping repeatedly — indicates a leak
• Sweet smell from the engine bay — coolant has a distinctive sweet odour
• White residue around the radiator cap or overflow tank
• White smoke from the exhaust — can indicate a head gasket issue

The Importance of Coolant Condition

Coolant degrades over time, losing its anti-corrosion properties. Old coolant becomes acidic and attacks the aluminium components in your engine and cooling system — particularly on European vehicles. Most manufacturers recommend a coolant flush every 2 years or 30,000–40,000 km. We test coolant condition at every major service.

Frequently Asked Questions — Radiator Repairs Artarmon

Q: My car is overheating — what should I do?

A: Pull over safely and turn the engine off immediately. Do not open the radiator cap when the engine is hot — the system is under pressure and scalding coolant can escape. Call us and we can advise on whether the car can be driven in or needs towing. Driving an overheating engine even for a short distance can cause thousands of dollars of damage.

Q: How long does a radiator last?

A: Modern plastic-tank aluminium radiators typically last 10–15 years or 150,000–200,000 km under normal conditions. Age, road damage, and poor coolant maintenance accelerate deterioration.

Q: Can a leaking radiator be repaired rather than replaced?

A: Small leaks in metal radiators can sometimes be repaired. Plastic-tank radiators with cracked or damaged end tanks are generally replaced — repair is rarely reliable long-term. We’ll assess and recommend the most cost-effective approach.

Q: How do I know if my water pump is failing? A: Signs include coolant leaking from the pump weep hole, engine overheating, and sometimes a whining noise from the pump bearing. Water pump failure is often sudden — proactive replacement at the timing belt service (when the system is already accessible) is the best approach.
