There’s never a good time for engine trouble. Whether you’re commuting to work or heading out for a weekend getaway, a breakdown can throw your plans into chaos. The good news? Many of the most common engine problems we see here at Brock Road Garage could’ve been prevented with regular maintenance.
Below, we break down the five most frequent causes of engine repairs in Guelph—and share some practical tips to help you avoid them.
1. Skipping Oil Changes
Neglecting oil changes is one of the fastest ways to damage your engine. Over time, oil becomes dirty and loses its ability to lubricate, leading to friction, overheating, and eventually engine failure.
What to watch for:
- Ticking or knocking sounds from the engine
- A burning oil smell
- The oil light flickering on your dashboard
- Poor fuel efficiency
Prevention Tip:
Most vehicles need an oil change every 5,000 to 8,000 km. Not sure if you’re overdue? Swing by your trusted Guelph mechanic and we’ll check it for you.

2. Overheating
Engines don’t like running hot—and when they do, things can go south quickly. Overheating is usually caused by low coolant levels, a clogged radiator, a faulty thermostat, or a worn-out water pump.
Red flags include:
- Steam coming from under the hood
- Sweet smell of coolant
- Temperature gauge creeping into the red
- Dashboard warning lights turning on
Prevention Tip:
Check your coolant level regularly—especially when seasons shift from freezing cold to scorching hot. If you’re planning a road trip or haven’t had your engine looked at in a while, book a cooling system check-up in Guelph to be safe.

3. Timing Belt or Chain Issues
The timing belt (or chain) keeps your engine’s valves and pistons moving in sync. If it slips or snaps, you could be facing serious engine damage—and it often happens without warning.
Common signs:
- Ticking noises from the engine
- Oil leaks near the front of the motor
- Engine misfires or won’t start
Prevention Tip:
Most timing belts need replacing somewhere between 100,000 and 160,000 km. Don’t wait until something goes wrong—ask your Guelph mechanic to check it during your regular service. Staying ahead of this one can save you a major repair bill.
4. Fuel System Problems
If your engine isn’t getting enough fuel, it can stall, sputter, or struggle to start. Dirty fuel injectors, clogged filters, or a worn-out pump are often to blame.
What to look for:
- Slow starts or trouble turning over
- Engine stalling while driving
- Hesitation when accelerating
- Drop in fuel mileage
Prevention Tip:
Use quality fuel and have your filter replaced as part of your vehicle’s maintenance schedule. If the car doesn’t feel quite right, don’t wait—get it checked before it becomes a bigger issue.
5. Oil Leaks & Gasket Wear
Your engine’s gaskets help keep oil where it belongs. But over time, those gaskets wear down, and leaks can develop—leading to overheating and serious internal damage.
Signs to spot:
- Oil stains under your car
- Burning oil smell
- Smoke from under the hood
- Low oil levels between changes
Prevention Tip:
Check your oil regularly and keep an eye on the ground where you park. If you notice anything unusual, book a visit to your local garage in Guelph. A quick look now could save you from a costly repair later.
Don’t Ignore the Check Engine Light
It might be something minor—or it might not. Either way, the check engine light is your car’s way of saying “something’s not right.” Our team uses advanced diagnostic tools to find the issue fast, so you’re not left guessing.
