Your vehicle’s cooling system works hard every time you drive. Whether you own a family car, work ute, 4WD, delivery van or light truck, the radiator and cooling system are essential for controlling engine temperature, protecting internal components and maintaining reliable performance.

At A.B. Automotive Services in Tottenham, we provide professional radiator and cooling system maintenance, diagnostics and repairs for passenger vehicles, 4WDs, light commercial vehicles and heavy trucks. As an independently owned Repco Authorised Service centre, we combine trusted workmanship with quality parts and expert care.

• Radiator – releases heat from coolant into the air
• Water pump – circulates coolant through the engine
• Thermostat – regulates coolant flow based on temperature
• Cooling fan – improves airflow through the radiator at low speeds
• Radiator hoses – carry coolant between components
• Coolant reservoir – allows coolant expansion and recovery
• Temperature sensors – monitor engine temperature and activate fans

If one part fails, the entire system can be affected.

• Prevent overheating in summer traffic
• Protect cylinder heads and head gaskets
• Reduce corrosion inside the radiator and engine
• Improve heater performance in winter
• Extend water pump and hose life
• Maintain fuel efficiency and engine performance
• Reduce roadside breakdown risk

For tradies, fleet vehicles and truck operators, preventative maintenance can also reduce costly downtime.

• Temperature gauge running high
• Engine overheating warning light
• Coolant leaks under the vehicle
• Sweet smell from engine bay
• Low coolant level requiring frequent top-ups
• Steam from bonnet area
• Heater not producing warm air
• Cooling fan running constantly
• Sludge or rust-coloured coolant
• Squealing noises from water pump or belts

Even minor symptoms can indicate a developing fault.

• Radiator Repairs & Replacement
  Blocked, leaking or corroded radiators reduce cooling efficiency. Replacement may be required if damage is extensive.
• Thermostat Replacement
  A stuck thermostat can cause overheating or slow warm-up.
• Water Pump Replacement
  A worn pump may leak, make noise or fail to circulate coolant correctly.
• Hose & Clamp Replacement
  Rubber hoses age, harden and crack over time.
• Cooling Fan Repairs
  Electric fan motors, relays, sensors or wiring faults can stop airflow through the radiator.
• Coolant Flush & Renewal
  Old coolant loses corrosion inhibitors and can damage internal passages.
• Pressure Testing & Leak Detection
  Specialised equipment helps locate hidden leaks quickly.
• Truck & Commercial Cooling Repairs
  Heavy-duty vehicles often require larger system diagnostics, hose inspections and load-related cooling checks.

• Head gasket failure
• Warped cylinder head
• Engine oil breakdown
• Transmission cooling issues (where integrated with radiator)
• Turbocharger heat stress
• Heater core blockage
• Sensor and electrical faults caused by excess heat

Early repairs are usually far less expensive than major engine work.

• Have coolant checked during routine servicing
• Replace coolant at manufacturer intervals
• Never ignore temperature warnings
• Inspect for leaks or stains under the vehicle
• Keep radiator fins clear of debris
• Replace ageing hoses before failure
• Book a pre-trip inspection before towing or long drives
• Use the correct coolant type for your vehicle

Never remove a radiator cap when the engine is hot.

Did you know? .... Your engine runs most efficiently within a narrow temperature range. Too hot causes damage, but too cold can also increase fuel use, emissions and engine wear. That is why the thermostat is such a small but important component.
