What Is Coolant?

Coolant is a mixture of water and antifreeze that circulates through your vehicle’s engine and radiator to regulate its temperature. It prevents freezing in cold temperatures and overheating in the hot temperatures of Porter, TX. Coolant also contains additives that protect against corrosion and scale buildup within the cooling system.

How to Check Coolant Level

• Safety First: Before you start, ensure that your engine is completely cool. Never attempt to open the radiator cap when the engine is hot, as it can release scalding steam.
• Locate the Coolant Reservoir: Open your vehicle’s hood and locate the coolant reservoir. It’s usually a translucent plastic container near the radiator.
• Check the Coolant Level: The coolant reservoir will have “low” and “high” markings. Ensure your vehicle is on a level surface and examine the coolant level against these markings. If the coolant level is below the “low” mark, your coolant is low.

What to Do If Coolant Level Low

If you find your coolant level low, it’s important to address the issue promptly:

• Top Up Coolant: Add a mixture of antifreeze and distilled water to the reservoir to reach the “high” mark. Follow your vehicle’s owner’s manual for the correct coolant-to-water ratio.
• Inspect for Leaks: Low coolant levels can be a sign of a leak in the cooling system. Inspect the area beneath your vehicle for any signs of leaks, such as puddles or stains.
• Address the Issue: If you suspect a leak or notice the coolant level dropping frequently, it’s recommended to have your vehicle inspected by a professional mechanic. Ignoring a coolant leak can lead to overheating and potential engine damage.

Understanding the Low Coolant Light

Many modern vehicles are equipped with a low coolant light warning on the dashboard. If the coolant level drops below a certain point, this light will illuminate. If you see a low coolant light, follow the same steps mentioned above to check and address the coolant level.

Maintaining the correct coolant level is crucial for preventing engine overheating, which can lead to costly repairs. In addition to checking the coolant level, it’s recommended to have a professional mechanic inspect your vehicle’s cooling system during routine maintenance to ensure there are no leaks or other issues.
