Cooling system and radiator repair in Oshawa, ON
The cooling system keeps the engine at the right temperature. An overheated engine can be badly damaged in minutes, so cooling problems are worth catching early.

What our cooling system service includes
Cooling system inspection
We check hoses, the radiator, the cap, the reservoir and the coolant level and condition.
Leak diagnosis
Coolant leaks show up as puddles, a sweet smell or a level that keeps dropping. We find where it is going.
Repair and coolant service
Hoses, radiator, thermostat and related parts repaired or replaced, and coolant serviced.
Signs of a cooling problem
- The temperature gauge climbs or the warning light comes on
- A sweet smell, steam or coolant puddles under the car
- The coolant level keeps dropping
- The cabin heater blows cold when the engine is warm
- Rust-coloured or muddy coolant in the reservoir
If it starts to overheat, stop
If the temperature gauge is climbing, pull over safely and turn the engine off. Driving an overheating engine is how a coolant leak turns into a very expensive repair.
Do not open the radiator cap while the engine is hot. Call us and we will tell you what to do next.
