The benefits of a trusted local mechanic
Choosing a local team for ongoing car care makes life easier in so many ways:
1) Peace of mind on the road
Regular servicing catches little issues before they become expensive problems. Fresh fluids, good brakes, healthy tyres and up-to-date software all add up to a safer car.
2) Better longevity and resale
A well-maintained vehicle simply lasts longer and feels better to drive. When it’s time to sell, a neat service history from a reputable Castle Hill workshop makes the listing more attractive.
3) Real support when you need it
Got an odd noise, warning light or vibration? Pop in, and we’ll listen—both to you and the car. It’s reassuring to know there’s a team nearby that already knows your vehicle’s history.
4) A plan that fits your driving
Short daily commutes, rideshare kilometres, weekend towing or a car that sits most of the week… maintenance should match how you actually use the vehicle. We help you set a sensible schedule that keeps costs predictable and performance consistent.
Our core services
We handle day-to-day maintenance through to complex diagnostics, across most makes and models—including late-model European, Japanese and Australian vehicles.
Logbook servicing (manufacturer-spec)
Keep your servicing on track with parts and fluids that meet the recommended specifications. We follow the correct service schedule for your model, reset service indicators, and stamp/record the service so your history stays complete.
Diagnostics & fault finding
Modern cars store a wealth of data. We use up-to-date scan tools and live data analysis to find what’s really causing that check-engine light, rough idle, misfire, or fuel economy drop—then confirm the diagnosis with practical tests so we fix the cause, not just the symptom.
Brakes: pads, rotors, hydraulics
Stopping power matters. We assess pad and rotor wear, calliper condition, brake fluid health and ABS operation. If you’re hearing squeals, feeling shuddering, or the pedal is going soft, we’ll sort it.
Steering & suspension
A tidy suspension makes every drive feel better—no knocks, no bouncy roll, and proper tyre wear. We inspect shocks, struts, control arms, bushings, tie-rods and power steering systems, then recommend what’s needed for a quiet, confident ride.
Tyres, wheel balancing & alignments
Good tyres are your only contact with the road. We check tread depth, wear patterns and pressures, arrange replacements when needed, and keep alignments in shape so the car tracks straight and tyres last longer.
Cooling systems
Overheating can escalate quickly. We pressure-test for leaks, check radiators and hoses, inspect water pumps and thermostats, and replace coolant to spec so temperatures stay where they should.
Air conditioning service
From weak airflow to warm air on a hot day, we diagnose leaks, test pressure, inspect cabin filters, and get the system blowing cold again. It’s not just comfort—clear, cool air helps you stay focused behind the wheel.
Batteries & charging systems
Slow starts? Flickering lights? We test battery health, alternator output and starter performance, then guide you on the right replacement when required.
Engine timing & driveline
Timing belts/chains, accessory belts, clutches, CV joints and driveshafts—these parts keep the engine and wheels in sync. We’ll advise on replacement intervals and symptoms to watch for, then complete the work with careful attention to alignment and torque settings.
Fuel & intake systems
If your car hesitates, surges or drinks more fuel than it used to, the issue could be injectors, sensors or airflow measurement. We clean, test and replace components as needed, then road-test to confirm the fix.
Exhaust & emissions
Audible leaks, rattles or a failed inspection often point to cracked pipes, worn mounts or sensor issues. We diagnose the system end-to-end and restore quiet, clean operation.
Transmission servicing (automatic & manual)
Smooth shifting depends on clean fluid and healthy components. We service autos, dual-clutch and conventional manuals as recommended, and flag early warning signs before they become major repairs.
4WD, towing & touring setup
From preventative maintenance before a long trip to setting the car up for towing or touring, we help you leave Castle Hill with confidence. We focus on cooling, brakes, suspension, load handling and simple reliability checks that pay off on the highway.
Rego checks & roadworthy inspections (where applicable)
If you need an inspection, we’ll walk you through what’s required and handle the process efficiently so you can tick that box and get on with your week.
Pre-purchase inspections
Looking at a used car? Bring it in. We’ll check service history, scan for hidden faults, inspect underbody and driveline, and give you a clear picture so you can make a smart decision.
Not sure which service you need? Tell us what the car’s doing—noises, smells, vibrations, warning lights—and we’ll guide you from there.
How we work: the Tassell Automotive way
Car servicing can feel complicated from the outside. Our approach keeps it simple, transparent and calm.
- Listen & look
We start with your description of the symptoms, then do an initial inspection to confirm what we’re dealing with. - Diagnose with intent
We use scan data, test drives and physical checks to narrow down the cause. No guessing, no “replace-it-all” thinking. - Explain your options
You’ll get a straightforward explanation of what we’ve found, why it matters and the logical next steps. If there’s more than one path forward, we’ll outline them. - Do the work properly
We follow the correct procedures, use suitable parts and fluids, and road-test the car to make sure the result matches the plan. - Follow-up & plan ahead
You’ll get notes on anything to monitor and a sensible timeline for future maintenance, so there are no surprises.
Everyday problems we fix (and how you’ll feel the difference)
- The car’s lost its zip
Often a mix of sensors, airflow, ignition or fuel delivery. We track it down and restore smooth, predictable power. - Brakes feel average
Shudder, squeal or a long pedal? We address wear, fluid age or rotor condition so stops are quiet and confident. - Steering pulls or tyres wear strangely.
Alignment or suspension components might be tired. We correct the geometry and replace worn parts so the car tracks straight. - Air-con can’t keep up.
Leak checks, component testing and proper service get cold air back on your side. - Warning lights with no obvious symptoms
We scan, test and advise whether it’s urgent or safe to keep driving until a scheduled visit. - Rattles & clunks
From heat shields to bushings, we locate the source and tidy it up so the cabin stays quiet.
Tips to keep your car happier between visits
- Check tyre pressures monthly
Correct pressures improve stopping distance, tyre life and fuel economy. - Listen for new noises.
A squeak, clunk or whine that wasn’t there last month is worth a quick chat. - Top up washer fluid & keep wipers fresh.
Clear vision is an easy win—especially during Hills District downpours. - Warm up gently
Give the engine a minute of light driving before heavy acceleration. Fluids need time to circulate. - Stick to a sensible service interval.
Even if you’re not driving many kilometres, time matters—fluids age and seals dry out.
Who we help
- Families juggling school runs and weekend sports who need dependable cars that just start and go.
- Commuters who rack up kilometres every week and want predictable maintenance.
- Tradies & small business owners who rely on vans and utes to earn a living and can’t afford downtime.
- Enthusiasts & tourers who want their setup dialled for long trips, towing or occasional spirited drives.
- First-car buyers are looking for clear advice and easy maintenance plans.
If you fit one of these—or none—we’ll tailor our approach to how you use your vehicle.

Chances are yes. We service most brands commonly seen around Castle Hill, from daily commuters to SUVs and 4WDs. If you’ve got something unusual, give us a call and we’ll confirm.

If you have something specific in mind, talk to us first. We’ll advise what’s suitable for your car and the job at hand.
