Q&A

Why is it important to check and test your car's coolant?

Checking and testing your car's coolant ensures that your engine and cooling system are protected from freezing, overheating, and corrosion. It also helps maintain a comfortable temperature inside your car.

How often should you check your car's coolant?

It is recommended to check your car's coolant at least once a month or before the start of the winter season. Regularly checking your coolant levels can help prevent potential cooling system issues.

How do you check the coolant level in your car?

To check the coolant level, open the hood and locate the coolant reservoir. Make sure the engine is cool, then remove the reservoir cap and check the fluid level. The coolant level should be at or above the minimum mark.

How do you test the freezing point of your car's coolant?

To test the freezing point of your car's coolant, use an antifreeze tester or hydrometer. Insert the tester into the coolant reservoir, squeeze the bulb, and read the freezing point on the scale. Make sure the reading is below the lowest expected winter temperature.

What should you do if the coolant level or freezing point is low?

If the coolant level is low, add a 50/50 mix of antifreeze and distilled water to the coolant reservoir until it reaches the recommended level. If the freezing point is high, you might need to drain some of the coolant and add concentrated antifreeze to achieve the desired freezing point.
