Locals who keep coming back
Real, verified reviews of our Malaga workshop and the team behind Radiators Perth.
Wonderful service, the staff went the whole mile and the price was half what the local shop could do. Highly recommend.
Walked me through the problems and the best lesson was on maintenance, gotta do it regularly. Really appreciated the honesty.
Great friendly service, fixed it quickly and the price was great. Will come back for anything cooling-related.

Overheating, coolant loss or a running-hot gauge? We pressure-test and diagnose the whole cooling system, from radiator and fan to thermostat, water pump and hoses.
Book a Cooling Check ›Drivability Tuning
Rough idle, hesitation or drinking fuel? Drivability tuning for daily-driven cars, 4x4s and work vehicles, smoother running and better economy. Not a performance or dyno shop.
Ask About Drivability Tuning ›Thermostats, Pumps & Hoses
Overheating often is not the radiator at all. We replace failing thermostats, water pumps, fans, caps and hoses, and pressure-test the system so it is fixed for good.

Common questions
What does it cost to diagnose a cooling, A/C or tuning fault?
We charge a flat diagnostic fee that gets credited toward the repair if you go ahead with us. Give us the symptoms over the phone and we will quote the diagnosis up front, no surprises.
My car is overheating, do I need a new radiator?
Not always. Overheating can be a thermostat, water pump, fan, hose or head gasket issue as well. We pressure-test and diagnose properly before recommending replacement, and often a repair or single component fix is all it needs.
Why is my car A/C blowing warm?
Usually low refrigerant from a leak, a faulty compressor, or a blocked condenser. We diagnose the exact cause, quote the fix and re-gas properly once the leak is sorted. A re-gas without fixing the leak just costs you twice.
What kind of tuning do you do?
Drivability tuning only, smoother running, better fuel efficiency, and resolving rough idle, hesitation and drive-away issues on daily-driven cars, 4x4s and work vehicles. Sensor and calibration work as part of a proper diagnosis.
Do you do performance tuning, dyno work or ECU flashing for power?
No, Radiators Perth is not a performance workshop. If you are chasing horsepower, dyno tuning or modified builds you will want a dedicated performance shop. What we do is honest drivability and efficiency tuning for vehicles that just need to run right.
Do you work on 4x4s, trucks and heavy machinery?
Yes, cooling, A/C and drivability tuning for cars, 4x4 tourers, tradie utes, work trucks, farm equipment and heavy machinery. Heavy-duty parts, proper fit, priority booking for fleets.
How long do repairs usually take?
Most jobs, radiator repairs, re-gas, straightforward replacements and drivability tuning, are finished the same day. For bigger work like heavy machinery cores or hard-to-source parts we give you a realistic timeframe up front.
Do you guarantee your work?
Yes. Every repair carries a workmanship guarantee. If something we have worked on is not right, bring it back and we will fix it, no argument.
