Why do I need a cooling system flush?
The engines in many of the new GM vehicles today are smaller than they used to be, which consequences in a great deal of heat. The cooling system is responsible to maintain the engine at an acceptable operating temperature. A coolant system flush insures the anti-freeze is doing the correct job. Anti-freeze has a lifespan which needs to be changed periodically. It contains chemicals that prevents corrosion, however anti-freeze that is old will actually speed up corrosion.
How often should I get a cooling system flush?
Every 5 years or 240,000km. At that time, we will also make sure everything is operating as it should and replace the fluid
