Malaga Locals Backing the Workshop
Straight from the customers whose radiators and A/C we've fixed. Real testimonials from real jobs.
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.
Air con was blowing warm on a 40-degree day. Booked in the next morning, regassed, diagnosed a small leak and fitted a new condenser — out the same day. Cold air ever since.
HiLux was overheating towing the van. Radiators Perth pressure-tested it properly, found the actual issue and quoted a fair fix. Straight-up crew — no upselling.
Radiator on the work truck let go on a Monday. Called Radiators Perth, they had a replacement sourced and fitted by end of Tuesday. Kept us moving — huge.

We service everything from a daily driver through to a work-hard 4x4, truck and heavy machinery — with genuine parts, honest advice and a workmanship guarantee on every job.

Frequently Asked Questions
Everything you need to know before booking your vehicle in.
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'll quote the diagnosis up front — no surprises.
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 — often a repair or single component fix is all it needs.
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 regas without fixing the leak just costs you twice.
Drivability tuning only — smoother running, better fuel efficiency, 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.
No — Radiators Perth is not a performance workshop. If you're chasing horsepower, dyno tuning or modified builds you'll want a dedicated performance shop. What we do is honest drivability and efficiency tuning for vehicles that just need to run right.
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.
Most jobs — radiator repairs, regas, straightforward replacements, drivability tuning — are finished the same day. Bigger work like heavy machinery cores or hard-to-source parts we'll give you a realistic timeframe up front.
Yes. Every repair carries a workmanship guarantee. If something we've worked on isn't right, bring it back and we'll fix it — no argument.
