Coolant Leaks - Cooling System Flush

Cooling System Repairs

Les Dobos has the equipment and technicians to accurately diagnose and repair all vehicle cooling system related problems. Our team has decades of experience of repairing vehicle cooling systems in Calgary. We provide prompt and quality service at a great cost. Our technicians are trained to inspect engine antifreeze/coolant quality and to diagnose any leaks and associated potential problems.

Over time, as the engine antifreeze/coolant degrades due to high operating temperatures, it becomes corrosive, leading to failure of hoses, thermostats, radiators, water pumps and heater cores. Loss of antifreeze/coolant can cause engine overheating, and hence engine failure. Insufficient antifreeze strength can result in freezing ruptures and hard starting problems in the winter.

Whether it is a preventive maintenance replacement of engine antifreeze / coolant, or the replacement of failed cooling system components, we will correctly diagnose and repair your vehicle.

5 Signs That Your Cooling System Needs to Be Repaired

White Steam coming from under the Hood

White smoke is a sure sign of overheating and you should pull over right away.

Rising Temperature Gauge

Another clear sign of radiator trouble is if the temperature gauge in your dashboard rises into the red-zone. While this likely represents overheating issues it may simply indicate a faulty thermostat.

Low Coolant Levels

When checking the coolant level in your vehicle, make sure the engine is cold to avoid burning yourself. If you find that your coolant level is low, you probably have a leak.


When checking the coolant level, look around the engine bay for discoloration or rusty spots. This could mean a pinhole leak in the cooling system.

Coolant Leak

If you notice a sweet smelling, green fluid leaking under your engine where you park your car you can bet on a coolant (aka antifreeze) leak. This needs to be addressed immediately in order to avoid major overheating problems.
