ZhoopZhoop Collision & Mechanical handles mechanical repair in Thornhill for cars, SUVs, pickups and commercial vehicles. Our Ontario-licensed 310S automotive service technicians and 310T truck and coach technicians diagnose and fix engines, transmissions, brakes, tires, alignment, suspension and electrical faults at 47 Guardsman Rd, Unit 2. We inspect first, give you a written quote, and don’t touch anything until you approve it.
Most people know us for collision work. The same building has a full mechanical side, so a car that needs bodywork plus a brake job, an alignment or a warning-light diagnosis doesn’t get passed between businesses.

Our mechanical services
Each core service has its own page covering symptoms, what the repair involves and the questions we hear most.
Diagnostics and check engine light
We scan the computer, then test the actual circuit or part the code points to. A code tells you where to look. It doesn’t tell you what’s broken. You get a plain-language report before any repair is quoted.
Engine repair
Misfires, oil and coolant leaks, overheating, timing belts and chains, head gaskets, and cooling-system parts such as water pumps, radiators and thermostats.
Transmission repair
Slipping, harsh or delayed shifts, CVT shudder, dual-clutch hesitation, and AWD and transfer case problems. We diagnose first, because many shifting complaints turn out to be fluid, software or sensor issues rather than a failed transmission.
Tires and brakes
Brake pads, rotors, calipers and fluid; tire sales, seasonal swaps and storage; TPMS sensor service.
Wheel alignment
Four-wheel alignments, with steering angle sensor reset and ADAS calibration done in the same building when your car needs it.
Suspension, shocks and struts
Struts, shocks, control arms, ball joints, tie rod ends, sway bar links, wheel bearings and springs, including pothole and collision damage.
Inspections and specialty services
- Ontario safety inspections for buying, selling or re-registering a vehicle.
- Uber and Lyft rideshare inspections for drivers who need a current inspection.
- ADAS camera and radar calibration, from $300.
- EV and hybrid service, including brakes, suspension, cooling and diagnostics.
- Key programming and immobilizer repair for lost keys, spare keys and no-start immobilizer faults.
- Auto glass and windshield replacement, from $350.
How a mechanical repair works here
- Inspect. A licensed technician confirms the complaint, road-tests where it’s safe, scans the systems and checks the parts involved.
- Quote. You get a written estimate that separates what must be fixed now from what can wait, with the reason for each item.
- Approval. Nothing gets done until you say yes. If we find something else once parts come off, we call you before going further.
- Repair. We do the work, clear codes, road-test again and walk you through what changed. You can ask to see your old parts.
We don’t offer mobile service. All work happens in our Thornhill shop.
Cars, SUVs, trucks and commercial vehicles
We work on everyday sedans and hatchbacks, family SUVs and minivans, pickup trucks, and work vans. Having 310T truck and coach technicians on the team means heavier and commercial vehicles get someone licensed for them, and our MTO authorization covers commercial inspections.
If you run a small fleet, such as contractor vans or delivery vehicles, call us to talk about scheduling so your vehicles aren’t all down at once. If you’re unsure whether your vehicle fits our bays, call 905-886-2737 and ask before you drive over.
Mechanical repair after a collision
A front or side hit rarely stops at the bumper. Radiators, AC condensers, cooling fans, control arms, tie rods, wheel bearings and sensors often take damage that isn’t visible from outside. Because our collision and mechanical teams share a building, we find and fix that damage during the same repair, and include it in the insurance estimate when it’s part of the claim.
Read more about hidden damage after a car accident, why a collision can affect alignment and suspension, and why warning lights sometimes appear after a crash. For the body side of the job, see collision repair in Thornhill. We work with all insurers and bill them directly; our insurance claims page explains how that works.
From the shop floor
What affects the cost of mechanical repair
- The diagnosis. Some faults show up in minutes. Intermittent electrical problems can take longer to pin down.
- Parts. New aftermarket, OEM and used parts differ in price and availability. We’ll tell you which options make sense for your car.
- Vehicle design. Some engines need far more labour to reach the same part.
- Follow-up work. Suspension and steering repairs usually need an alignment, and some also need ADAS calibration.
Visual estimates are free. Inspection or teardown estimates carry a fee, which is credited to the repair if you have it done with us. Call 905-886-2737 for current pricing.
Tires and mechanical closer to you: Active Green + Ross
Our group also runs four Active Green + Ross tire and auto centres. They’re a separate brand for tires and mechanical work, and they don’t do collision repair. If one of them is closer to home or work, it may be the easier stop for an oil change, tires or brakes:
- Active Green + Ross, Etobicoke (Dundas West)
- Active Green + Ross, Etobicoke (Rexdale)
- Active Green + Ross, Toronto (Danforth)
- Active Green + Ross, North York (Victoria Park)
All collision and body work happens here in Thornhill.

Mechanical repair FAQs
What mechanical repairs do you do in Thornhill?
We handle diagnostics and check engine lights, engine repair, transmission repair, brakes, tires, wheel alignment, suspension, and electrical faults. We also do Ontario safety inspections, rideshare inspections, ADAS calibration, EV and hybrid service, key programming and auto glass. Everything is done in-house at 47 Guardsman Rd, Unit 2, Thornhill, by Ontario-licensed 310S and 310T technicians.
Are your mechanics licensed?
Yes. Our mechanical technicians hold Ontario 310S automotive service technician licences, and we also have 310T truck and coach technicians for heavier and commercial vehicles. We’re an MTO-authorized inspection station for safety, structural and commercial inspections, and our collision technicians are I-CAR certified with 310B licences.
Do you give a quote before starting work?
Yes. We inspect the vehicle first, then give you a written quote that explains each item and separates urgent repairs from ones that can wait. No work starts until you approve it. If we find something new once parts are removed, we call you before doing anything more.
What warranty do you offer on mechanical repairs?
ZhoopZhoop offers a 90-day warranty on all work, plus a lifetime paint warranty on insurance repairs. If something we repaired isn’t right within the warranty period, bring the vehicle back and we’ll inspect it. Keep your invoice, because it lists exactly which parts and labour the warranty covers.
Can you fix mechanical damage caused by a collision?
Yes. Collisions often damage radiators, condensers, suspension parts, wheel bearings and sensors. Our collision and mechanical teams work in the same building, so we find and repair that damage during the same job. When it’s part of an insurance claim, we include it in the estimate and bill your insurer directly.
Do you work on trucks and commercial vehicles?
Yes. We service pickups, vans and commercial vehicles, and our team includes Ontario-licensed 310T truck and coach technicians. We’re also an MTO-authorized station for commercial inspections. If you’re not sure whether your vehicle fits our bays, call 905-886-2737 and ask before you drive over.
Do you offer mobile mechanic service?
No. All mechanical work is done at our shop at 47 Guardsman Rd, Unit 2, in Thornhill, where we have the lifts, scan tools and calibration equipment. If your vehicle can’t be driven safely, we can help arrange a tow to the shop. Call 905-886-2737 and we’ll talk you through it.
