The Ultimate Guide to Advance Auto Parts Coolant
Coolant, also known as antifreeze, plays a crucial role in maintaining your vehicle’s engine temperature, preventing overheating, and protecting against corrosion. With numerous options available at retailers like Advance Auto Parts and Walmart, selecting the right coolant can be overwhelming. This guide will provide an in-depth analysis of the various types of coolant, their applications, and key features to help you make an informed choice.
Types of Coolant and Applications
| Type of Coolant | Description | Best Used For |
|---|---|---|
| Ethylene Glycol | The most common type, provides freeze protection and raises boiling point. | Standard vehicles, general use. |
| Propylene Glycol | Less toxic alternative, often used in RVs and food industry applications. | Environmentally friendly options. |
| Organic Acid Technology (OAT) | Long-life coolant with additives that reduce corrosion. | Modern vehicles, especially those requiring extended change intervals. |
| Hybrid Organic Acid Technology (HOAT) | Combines OAT and traditional coolants with added benefits. | Domestic vehicles, especially those requiring high performance. |
| Water-based Coolant | Basic coolant solution often used for racing. | Racing applications, where performance is key. |
Understanding Coolant Functions
Coolant serves multiple purposes beyond merely regulating engine temperature. It prevents overheating, protects engine components from corrosion, and helps maintain optimal performance. The balance of water and coolant is essential; a 50/50 mix is typically recommended for effective freeze and boil-over protection.
How Coolant Affects Engine Performance
The right coolant enhances engine efficiency. It allows the engine to operate at a consistent temperature, which is crucial for optimal fuel combustion and emissions control. Additionally, proper coolant maintenance prevents the build-up of deposits, ensuring that the cooling system functions correctly.
Selecting the Right Coolant for Your Vehicle
When choosing coolant, consider the manufacturer’s specifications. Many vehicle manuals provide clear guidelines on which type of coolant is suitable. For example, Advance Auto Parts offers a variety of coolants tailored to specific makes and models, ensuring compatibility.
Factors to Consider
- Vehicle Age: Older vehicles may require traditional coolants, while newer models often benefit from OAT or HOAT formulations.
- Climate: Your geographical location can influence coolant choice. Colder climates may require a higher antifreeze concentration.
- Driving Conditions: Heavy-duty vehicles or those used in extreme conditions may benefit from specialized coolants.
Common Mistakes When Using Coolant
Many vehicle owners make mistakes when it comes to coolant maintenance. One common error is neglecting to check coolant levels regularly, leading to overheating or engine damage. Mixing different types of coolant can also result in chemical reactions that reduce effectiveness, so always use the recommended type.
Signs of Coolant Issues
- Overheating Engine: Indicates insufficient coolant or a possible leak.
- Coolant Leaks: Look for puddles under the vehicle; this may signal a hose or radiator issue.
- Discolored Coolant: If the coolant appears rusty or discolored, it may need replacement.
Technical Features of Coolants
| Feature | Ethylene Glycol | Propylene Glycol | OAT | HOAT | Water-based |
|---|---|---|---|---|---|
| Boiling Point (°F) | 223 | 225 | 265 | 265 | 212 |
| Freezing Point (°F) | -34 | -26 | -34 | -34 | 32 |
| Toxicity | High | Low | Low | Low | Low |
| Lifespan (miles) | 30,000 | 30,000 | 150,000 | 150,000 | 1,000 |
| Compatibility | Standard | RVs, Food | Modern | Domestic | Racing |
Importance of Regular Maintenance
Regular coolant maintenance is essential for a healthy engine. Routine checks can help identify leaks, ensure the correct coolant level, and maintain the proper mix. Most manufacturers recommend changing coolant every two years or 30,000 miles, whichever comes first.
How to Change Coolant
- Gather Tools: You’ll need a wrench, a funnel, and a container for old coolant.
- Drain Old Coolant: Locate the drain valve on the radiator and allow old coolant to flow into the container.
- Flush the System: Use a flush solution to clear out any deposits.
- Add New Coolant: Pour the new coolant into the radiator using a funnel.
- Check Levels: After running the engine for a few minutes, check to ensure levels are correct.

FAQ
What is coolant used for?
Coolant is a liquid that helps regulate engine temperature, prevents overheating, and protects engine components from corrosion.
How often should I change my coolant?
Most manufacturers recommend changing coolant every two years or 30,000 miles, but consult your vehicle’s manual for specific recommendations.
Can I mix different types of coolant?
Mixing different types of coolant can lead to chemical reactions that reduce effectiveness. Always use the recommended type for your vehicle.
What are the signs of low coolant?
Signs include an overheating engine, coolant leaks under the vehicle, or discolored coolant in the reservoir.
Is propylene glycol safer than ethylene glycol?
Yes, propylene glycol is less toxic and is often used in applications where safety is a concern, such as in RVs and food processing.
How do I check my coolant level?
Locate the coolant reservoir, usually a translucent plastic tank near the radiator, and check the level against the markings on the side.
What happens if I don’t change my coolant?
Failing to change your coolant can lead to corrosion, overheating, and potentially severe engine damage.
Can I use water instead of coolant?
While water can temporarily work, it lacks the protective properties of coolant and should not be used as a long-term solution.
What is OAT coolant?
Organic Acid Technology (OAT) coolant is a long-life coolant that uses organic acids to reduce corrosion and extend the time between changes.
Where can I buy coolant?
You can purchase coolant at auto parts retailers like Advance Auto Parts or Walmart, both of which offer a variety of options for different vehicles.
