How to Keep Your Engine Cool in the Summer Heat

Ontario summers can push your engine to the limit

When temperatures climb, your engine works harder to stay cool. If your cooling system isn’t in top shape, it can lead to overheating, reduced performance, and costly repairs.

1. Check your coolant levels

Coolant (antifreeze) prevents your engine from overheating. Make sure the reservoir is filled to the recommended level and the fluid is clean. If it looks rusty or cloudy, it’s time to flush and replace it.

2. Inspect your radiator and hoses

Cracks, leaks, and corrosion can cause coolant loss. Have your hoses, radiator, and clamps inspected regularly, especially before long drives.

3. Keep your fans running strong

Your vehicle’s electric cooling fan or belt-driven fan helps push heat away from the engine. A malfunctioning fan motor or sensor can quickly cause your engine to overheat.

4. Don’t ignore dashboard warnings

If your temperature gauge creeps up or you see a red warning light, pull over safely and turn off the engine. Continuing to drive can cause major damage.

5. Schedule a summer cooling system check
