Toronto’s Climate Impact on Diesel Engines
The Toronto’s unique weather patterns create specific diesel challenges:
Summer Heat (June-September):
- Overheating from gridlock on Gardiner / DVP ramps
- Dust and debris from construction zones clog filters
- Long idle times under heat waves strain alternators & A/C systems
Winter Cold (December–February):
- Frozen fuel lines & batteries in open-yard fleets
- Corrosion from salt-heavy downtown road conditions
- Electrical faults from moisture and short cycles
- Tight urban lots stress clutches, steering, and braking systems
- Stop-and-go delivery routes clog emission systems
- Roadwork detours increase wear on suspensions and brakes
