Coolant 101: Why and How Often to Change Coolant

What Is Coolant/Antifreeze?

Coolant/antifreeze is used to:

1. Aid heat transfer and raise the boiling point to prevent overheating.

2. lower freezing point of water to ensure a smooth start in winter.

3. Protect engine internals from rust and scales build-up and prevent internal corrosion.



Two Reasons Why You Need to Check the Engine Coolant in Winter:


1. To keep the engine cool

Radiator, a central component of a vehicle's cooling system, is designed to remove heat generated by the engine, and it has a lot of coolants circulating through it. During wintertime, especially if you are going to ski hills, there is a chance of coolant freezing when driving on the highway, especially when 40% of the engine failures are due to a failure to properly maintain the cooling system. If the coolant freeze, the radiator stops working, and without this control, the engine will overheat and may be damaged extensively. Checking the coolant level and freezing point and adjusting to the right glycol to water ratio could prevent this issue.


2. Remove rust and lime build-up.

Rust, scale, dusk, sludge and air reduce deposits build up over time. It is essential to eliminate those deposits because they can cause overheating and damage your cooling system or even your engine. Flushing coolant removes these contaminants.


Because of the two reasons listed above, it is essential to perform coolant tests twice a year, before winter and summer; and change the coolant regularly.


When/ How Often to Check:

It depends on the vehicle and the antifreeze level of pH; ideally, it should be changed after the first 100,000km and then every 50,000km.



Package Included:

• Perform coolant test and check for the level of pH and freezing point.

• Fill up coolant according to the vehicle required.

• Inspect fan belt and other system components to make sure it works properly.
