Customer Questions & Answers

  • Question: What is Prestone AS145 Stop Leak Repair used for?

    Answer: Prestone AS145 Stop Leak Repair is formulated to seal leaks in radiators, heater cores, and hoses. It works by penetrating the leak area and forming a durable seal that helps prevent coolant loss and overheating. This product is especially useful for older vehicles or those experiencing minor leaks due to wear and tear. Whether you’re dealing with a slow drip in your radiator or a slight leak in your hoses, this stop leak solution provides a quick fix to maintain vehicle performance.
  • Question: How does Prestone AS145 Stop Leak Repair work?

    Answer: The technology behind Prestone AS145 involves a specialized blend of sealing agents that flow into the leak point and expand upon contact with coolant. This application creates a strong bond that effectively seals the leak temporarily or until a more permanent solution can be implemented. The adhesive properties prevent the loss of coolant, ensuring your vehicle can maintain optimal operating temperature, especially during high-demand situations like towing or heavy traffic.
  • Question: Is Prestone AS145 suitable for all types of vehicles?

    Answer: Yes, Prestone AS145 Stop Leak Repair is compatible with a variety of vehicle types, including cars, trucks, and SUVs. It is designed to work with all conventional antifreeze/coolant formulations. However, it is always recommended to check your vehicle’s owner manual or consult with a professional mechanic if you have any concerns about compatibility, especially with high-performance or racing vehicles.
  • Question: How do I apply Prestone AS145 Stop Leak Repair?

    Answer: Applying Prestone AS145 Stop Leak Repair is straightforward. Start by ensuring your engine is cool and remove the radiator cap. Shake the bottle well, then pour the entire contents into the radiator or overflow tank. Run the engine until it reaches operating temperature to allow the sealant to circulate. It’s essential to monitor the leak for effectiveness afterward and consider following up with a professional assessment for any ongoing issues.
  • Question: Can I use Prestone AS145 with a coolant flush?

    Answer: While it’s possible to use Prestone AS145 Stop Leak Repair after a coolant flush, doing so may reduce its effectiveness. For best results, it is recommended to apply the stop leak after the coolant has been flushed and before adding new coolant. This ensures that the sealing agents can directly interact with any existing minor leaks without interference from old coolant or debris, creating a more effective seal.
  • Question: Will Prestone AS145 fix large leaks?

    Answer: Prestone AS145 Stop Leak Repair is designed to address small to moderate leaks rather than large or serious leaks. If your vehicle has significant leak issues, more extensive repairs such as replacing the radiator or hoses may be necessary. However, for minor leaks, especially in older vehicles, this product can prolong the life of the cooling system until a more comprehensive solution can be arranged.
  • Question: How often can I use Prestone AS145 Stop Leak Repair?

    Answer: Prestone AS145 Stop Leak Repair can be used as needed, particularly when you notice a leak in your cooling system. However, it’s important to assess the severity of the leak and consider it a temporary solution. If necessary, follow up with permanent repairs, especially for frequent users, as repeated applications may not address underlying issues in the long run.
  • Question: Is there a specific temperature range for using Prestone AS145?

    Answer: Prestone AS145 Stop Leak Repair should be applied when the engine is at a normal operating temperature, typically between 180°F to 220°F. However, it’s best to avoid extreme weather conditions during application—too cold can inhibit the flow of the sealing agents, while very high temperatures may affect the performance of other coolant in the system. Keeping the application within a typical operating range ensures optimal effectiveness.
  • Question: Can I use Prestone AS145 in a diesel engine?

    Answer: Prestone AS145 Stop Leak Repair is primarily designed for gasoline-powered vehicles; however, it can also be used in some diesel engines. It’s essential to confirm with the vehicle manufacturer’s recommendations regarding coolant additives for diesel engines, as they may have specific requirements to maintain peak performance and avoid complications with specialized cooling systems.
  • Question: Where can I buy Prestone AS145 Stop Leak Repair?
