Customer Questions & Answers
-
Question:
What is Prestone AF850 Dex-Cool 5050 Antifreeze used for?
Answer: Prestone AF850 Dex-Cool 5050 Antifreeze is primarily used to protect your vehicle's engine from extreme temperatures. It prevents freezing in cold weather and overheating in hot conditions, ensuring optimal engine performance. Besides temperature regulation, it also includes corrosion inhibitors that protect metal engine parts and help maintain the integrity of rubber hoses and gaskets, leading to a longer lifespan of your cooling system. -
Question:
Is Prestone AF850 compatible with all vehicles?
Answer: Prestone AF850 Dex-Cool is specifically formulated for GM vehicles that require Dex-Cool coolant, but it can also be mixed with other types of antifreeze in cases where no other options are available. However, it's recommended to avoid mixing different coolant formulas when possible, as doing so can reduce effectiveness and lead to engine issues. Always consult your vehicle’s owner manual to verify compatibility before use. -
Question:
What is the mixture ratio of Prestone AF850 Dex-Cool?
Answer: Prestone AF850 Dex-Cool is designed to be mixed with distilled water in a 50:50 ratio, which creates optimal cooling efficiency. This mixture helps achieve a freezing point of -34°F and a boiling point of 265°F with a pressure cap. Using the correct mixture is crucial because an improper ratio can lead to inadequate engine protection, overheating, or freezing in extreme conditions. -
Question:
How often should I change Prestone AF850 Dex-Cool antifreeze?
Answer: Generally, it is recommended to change your antifreeze every 5 years or 150,000 miles, depending on your driving conditions and manufacturer guidelines. Regular checks of the coolant level and condition can also help maintain engine health. If the antifreeze appears cloudy, contaminated, or has a strong odor, it should be replaced immediately to prevent engine damage and ensure effective temperature regulation. -
Question:
Can Prestone AF850 Dex-Cool be used in a vehicle that previously had traditional green coolant?
Answer: While it is best to avoid mixing different types of coolants, Prestone AF850 Dex-Cool can be used in vehicles previously filled with traditional green coolant. However, a complete flush and replacement of the old coolant is recommended to prevent chemical reactions that may harm your engine. This ensures that the benefits of Dex-Cool's formula, such as better corrosion protection and temperature management, can be fully realized. -
Question:
How do you properly dispose of antifreeze like Prestone AF850?
Answer: Proper disposal of used antifreeze is crucial for environmental protection. Prestone AF850 should never be poured down the drain or thrown in the trash, as it can be harmful to wildlife and ecosystems. Instead, take it to a local recycling center or an automotive shop that offers disposal services. Many municipalities also have hazardous waste collection programs that can safely handle antifreeze and other hazardous materials. -
Question:
Does Prestone AF850 contain ethylene glycol?
Answer: Yes, Prestone AF850 Dex-Cool contains ethylene glycol, which is an essential ingredient for the antifreeze's effectiveness in temperature regulation. Ethylene glycol lowers the freezing point of water and raises its boiling point, allowing for better performance under extreme conditions. It also works as a surfactant to provide corrosion protection and increase the lifespan of your vehicle's cooling system. -
Question:
What are the signs that my vehicle needs new antifreeze?
Answer: Signs that your vehicle may require new antifreeze include an overheating engine, coolant leaks under the vehicle, low coolant levels in the reservoir, or a sweet odor coming from the engine compartment. Additionally, an unusual gauge reading or warning light on your dashboard could indicate coolant issues. Addressing these signs promptly can prevent severe engine damage and maintain optimal vehicle performance. -
