Engine Maintenance

Laser-welded iridium spark plugs, direct-injection intake valve walnut blasting, ultrasonic fuel injector flushes, and scheduled factory service at 265 Centennial Pkwy N Unit 3, Hamilton.

Preventative Engine Maintenance

Modern engines require regular maintenance to maintain peak performance, fuel efficiency, smooth operation, and reliable ignition. Our preventative engine maintenance services are designed for modern gasoline, GDI, and hybrid engines.

At Centennial Tire & Auto Service, we provide factory-compliant engine tune-ups using OEM-quality ignition components and specialized cleaning procedures to restore combustion efficiency and protect long-term engine performance.

Peak Combustion

Over time, internal combustion engines can lose horsepower, consume more fuel, and develop rough idle vibration as spark plug gaps widen, ignition coils weaken, and carbon deposits build up on intake valves and throttle plates.

Our preventative engine tune-up service restores crisp throttle response, helps eliminate cold-start hesitation, and optimizes fuel burn using high-grade OEM ignition hardware and specialized intake cleaning chemicals.

Laser-Iridium Spark Plugs

Replacing eroded electrode plugs with factory pre-gapped iridium/platinum spark plugs, torqued to exact cylinder-head specifications.

Ignition Coil & Boot Service

Testing secondary ignition coil resistance and replacing deteriorated dielectric insulating boots to help eliminate high-load spark blowout.

GDI Intake Carbon Cleaning

Removing heavy, hard carbon deposits from intake valves to restore unrestricted airflow and improve engineIf your vehicle is experiencing rough idle, sluggish acceleration, increased fuel consumption, or breathing.

Serpentine Drive Belts & Tensioners

EPDM accessory drive belt replacement, alternator pulley decoupler inspection, and hydraulic tensioner dampener testing.

WARNING SIGNS

Symptoms Your Engine Needs a Tune-Up

If your vehicle is experiencing rough idle, sluggish acceleration,
increased fuel consumption, or difficult cold starts, your engine may
require preventative maintenance.

Rough Idle & Steering Vibration — Worn spark plugs can cause uneven combustion across cylinders, resulting in rough idle and noticeable steering-wheel vibration.
Sluggish Acceleration / Flat Spots — Carbon buildup can restrict intake airflow, while restricted fuel injectors may reduce fuel delivery and engine performance under load.
Noticeable Rise in Gas Consumption — Incomplete combustion can cause the ECU to compensate with additional fuel, reducing overall fuel economy.
Extended Cranking on Cold Starts — Weak ignition voltage can make it harder to ignite cold fuel during freezing Ontario weather, resulting in extended engine cranking.

Preventative Maintenance Checks

Regular engine maintenance helps prevent performance problems before they
become expensive repairs. Our technicians inspect ignition, fuel delivery,
intake airflow, and accessory-drive components according to the vehicle’s
service requirements.
