Our mobile workshop is equipped to handle the vast majority of servicing, maintenance and repair work on-site. Below is the full range of services we offer to drivers across Harrisdale and surrounding suburbs.
Auto Electrical Diagnostics & Repair
Modern vehicles rely on complex electrical systems, and when something goes wrong, warning lights on the dash, flickering headlights, faulty central locking or power windows that won’t budge, pinpointing the fault takes the right equipment and experience. Our mobile auto electricians use advanced diagnostic scan tools to accurately identify electrical faults at your Harrisdale home or workplace, then repair them on the spot wherever possible. From wiring issues and blown fuses to sensor faults and charging system problems, we sort your auto electrical troubles without your car ever leaving the driveway.
Brake Service & Repairs
Your brakes are your vehicle’s single most important safety system, and they should never be left to chance. If you’ve noticed squealing or grinding noises, a spongy brake pedal, vibration when braking or the car pulling to one side, call us straight away. Our mobile brake service in Harrisdale covers brake pad and rotor replacement, brake fluid flushes, drum brake repairs and full brake system inspections. We inspect, measure and replace worn components on-site using quality parts, so you can drive away with complete confidence in your stopping power.
Car Air Conditioning Service & Repair
Perth summers are unforgiving, and a car air conditioner that blows warm air makes every trip miserable. Our mobile car air conditioning service in Harrisdale includes system inspections, leak detection, re-gassing, compressor checks and component repairs. If your aircon is blowing warm, smells musty or simply isn’t as cold as it used to be, we’ll diagnose the cause at your location and restore icy-cold comfort to your cabin, often in a single visit.
Car Battery Repairs & Replacements
A flat or failing battery is the most common reason cars won’t start, and it always seems to happen at the worst possible moment. The good news? It’s also one of the easiest problems for us to fix. Call our mobile battery replacement service in Harrisdale and we’ll come to you — at home, at work or on the roadside, test your battery and charging system, and fit a quality new battery on the spot if needed. We carry batteries to suit most makes and models, so in most cases you’ll be back on the road within the hour.
Alternator Replacement
Your alternator keeps the battery charged and powers your vehicle’s electrical systems while the engine runs. When it starts to fail, you might notice a battery warning light, dimming headlights, strange whining noises or repeated flat batteries. Left unchecked, a failing alternator will leave you stranded. Our mobile mechanics test your charging system at your Harrisdale location and, if the alternator is at fault, replace it on-site with a quality unit, saving you an expensive tow to a workshop.
Radiator Replacement
An overheating engine can cause catastrophic and costly damage in a matter of minutes, so cooling system problems demand immediate attention. If you’ve spotted coolant leaks under the car, a rising temperature gauge or steam from under the bonnet, stop driving and give us a call. We carry out radiator inspections, coolant flushes, hose replacements and full radiator replacements at your home or workplace in Harrisdale, getting your cooling system back to peak condition before serious engine damage occurs.
Drive Belt Replacement
Your drive belt (serpentine belt) powers essential components including the alternator, power steering pump, water pump and air conditioning compressor. A squealing noise from the engine bay, visible cracking or fraying on the belt, or a sudden loss of power steering are all signs it’s due for replacement. If a drive belt snaps while you’re driving, you’ll lose multiple systems at once, so don’t wait. Our mobile drive belt replacement service in Harrisdale has you covered with quality belts fitted on-site, quickly and affordably.
Wrong Fuel Extraction
Put petrol in a diesel, or diesel in a petrol? It happens more often than you’d think, and the most important thing is not to start the engine. Starting the car circulates the wrong fuel through the system and can cause expensive damage to the fuel pump, injectors and engine. Call Mechanic On Wheels immediately and our mobile wrong fuel extraction service will come to you anywhere in Harrisdale, safely drain and flush the contaminated fuel from your tank and fuel system, refill with the correct fuel and have you safely back on the road, usually without any lasting damage at all.
Starter Motor Replacement
If you turn the key and hear a single click, a grinding noise or nothing at all, but your battery tests fine, the starter motor is the likely culprit. A failing starter will only get worse, and eventually your car simply won’t start at all. Our mobile mechanics diagnose starter motor faults at your Harrisdale location and replace the unit on-site with a quality replacement, so there’s no need to organise a tow truck for a car that won’t turn over.
Spare Tyre Replacement
A flat tyre on Ranford Road or Nicholson Road during peak hour is stressful enough without trying to wrestle a jack on the verge. If you’ve copped a puncture and can’t (or would rather not) change the tyre yourself, give us a call. We’ll come to your location anywhere in Harrisdale, fit your spare tyre safely and check the condition and pressure of your remaining tyres while we’re at it. If your spare isn’t roadworthy, we’ll advise you on the safest next steps so you’re never left guessing.
Logbook Services
Keeping your new car warranty intact doesn’t mean you’re locked into dealership servicing. Under Australian law, any qualified mechanic can carry out logbook servicing without affecting your manufacturer’s warranty, and we do it at your home or workplace in Harrisdale, usually for considerably less than the dealership charges. Our logbook services follow your manufacturer’s service schedule to the letter, use quality parts and lubricants that meet manufacturer specifications, and we stamp your logbook on completion. Dealership-standard servicing, doorstep convenience, honest pricing, it’s the best of all worlds.
Mobile Car Repairs
Beyond scheduled servicing, our mobile workshop handles a huge range of general car repairs across Harrisdale. Suspension components, cooling system repairs, leaks, belts and hoses, ignition problems, sensor replacements, exhaust issues and much more, if it can be repaired safely on-site, our technicians will get it done. If a job genuinely requires a hoist or specialist workshop equipment, we’ll tell you honestly and point you in the right direction rather than attempting a job that can’t be done properly in the field. That’s our commitment to doing things right.
Oil Change
Regular oil changes are the cheapest insurance your engine will ever get. Fresh, clean oil keeps engine components lubricated, reduces wear and helps your car run smoothly and efficiently for years to come. Our mobile oil change service in Harrisdale includes draining the old oil, fitting a new quality oil filter, refilling with the correct grade of oil for your vehicle and disposing of the old oil responsibly. We’ll also cast an expert eye over your fluids, belts and battery while we’re under the bonnet, all from your own driveway.
Vehicle Diagnostics
Check engine light glowing on the dash? Don’t ignore it, and don’t guess. Our mobile vehicle diagnostics service uses professional-grade scan tools to read your car’s onboard computer, identify fault codes and accurately pinpoint the underlying problem — whether it’s a faulty sensor, an emissions issue or something more serious. We come to you in Harrisdale, explain the findings in plain English, give you an honest assessment of what needs fixing now versus what can wait, and provide a clear quote before any repair work begins.
Pre-Purchase Car Inspection
Buying a used car in or around Harrisdale? A professional pre-purchase inspection is the smartest few dollars you’ll ever spend. Our mobile mechanics meet you at the seller’s location and conduct a thorough inspection covering the engine, transmission, brakes, suspension, steering, tyres, electrical systems, fluid condition and signs of accident damage or wear. You’ll receive an honest, independent report on the vehicle’s true condition, giving you the confidence to buy, the knowledge to negotiate a better price, or the warning to walk away from a lemon.
