Signs Your Cooling System Needs Attention

Is your gauge in the red? Pull over as soon as it's safe. Continuing to drive risks head gasket failure and serious engine damage. Call us on (08) 9800 9011.

What we do

Cooling System Services

Radiator Replacement & Repair

All makes and models. We assess first — not every issue needs a full replacement. OEM-spec or quality aftermarket radiators suited to your vehicle.

Coolant Flush & Thermostat

Old coolant causes corrosion. A faulty thermostat is one of the most common causes of overheating. We handle both as part of cooling system servicing.

Water Pump & Pressure Testing

Failing pump or a mystery coolant leak? We replace water pumps and run pressure tests to pinpoint exactly where the system is failing.

Everything We Cover

Radiator Replacement

All makes and models — passenger vehicles, 4WDs, diesels, utes, and light commercials. OEM-spec or quality aftermarket radiators suited to your vehicle.

Radiator Repairs

Not every cooling issue needs a full replacement. We assess the radiator first and repair where it makes sense.

Coolant Flushes

Old or contaminated coolant loses effectiveness and causes internal corrosion. We flush and replace with the correct spec — recommended every 2 years or 40,000 km.

Thermostat Replacement

A faulty thermostat is one of the most common causes of overheating. We inspect and replace as part of cooling system diagnostics.

Water Pump Replacement

A failing water pump causes overheating and often makes a grinding or whining noise before it fails completely.

Pressure Testing

Losing coolant but can't find a visible leak? A pressure test pinpoints exactly where the system is failing.

Hoses & Clamps

Coolant hoses deteriorate over time and can fail without warning. We inspect and replace as part of cooling system servicing.

4WDs, Diesels & Towing Vehicles

4WDs running through sand, bull dust, and corrugated WA tracks in summer put serious strain on the cooling system. If you're planning a big trip or your vehicle has been running warm under load, get the cooling system checked before you go.

Questions

Frequently Asked Questions

My car overheated — can I still drive it?
If the gauge hit the red or the engine warning light came on, stop as soon as it's safe and call us on (08) 9800 9011. Continuing to drive risks serious and expensive engine damage.
How often should I flush my coolant?
Most manufacturers recommend every 2 years or 40,000 km, but it varies. We can check what's correct for your make and model when you come in.
Can a leaking radiator be repaired, or does it need replacing?
Depends on the location and severity. Some leaks can be repaired cost-effectively; others are better resolved with a replacement. We'll assess it honestly.
Could my overheating be caused by something other than the radiator?
Yes — a faulty thermostat, failing water pump, cracked head gasket, or blocked cooling passages can all cause overheating. We diagnose the root cause, not just the symptom.
How long does a radiator replacement take?
Most replacements are completed within a day. We'll give you a timeframe when you book.
