Radiator Care FAQs

FAQsMaintenance TipsDIY Video
 What is the best coolant concentration for a vehicle? Can I use 100% concentrate?

We recommend that you use between a 50% and 70% concentration of coolant. At least 50% is necessary to give the adequate amount of corrosion and boilover protection. We do not recommend more than 70% concentration since this may cause restriction of the heat transfer capabilities and corrosion protection.

 Is 1 (one) bottle of Prestone Coolant Ready-to- Use enough?

Yes, all cars or light duty trucks of any make and model can use this coolant for continuous protection against overheat and boilover, rust and corrosion. It is highly recommended for old cars too.

 Can I use Prestone Coolant Ready-to- Use on my brand new car?

Yes, all cars or light duty trucks of any make and model can use this coolant for continuous protection against overheat and boilover, rust and corrosion. It is highly recommended for old cars too.

 Why it is important to take care of my engine’s cooling system?

The cooling system controls the ideal operating temperature of your vehicle, providing the best engine performance and the least wear. If your vehicle’s radiator fails to keep your engine in the proper temperature, your vehicle will not only break down but may cause massive inconvenience. It is not safe to be on board a vehicle that is so close to its temperature limit. Thus, proper care is necessary.

 Is it safe to use Prestone Coolant with my current brand of coolant?

Yes. Prestone Coolant is safe for use on vehicle makes and models. It is even safe to mix with other coolant that has a different color.

 Why shouldn't I use water in my radiator system?

Ordinary water has contaminants and harmful components that can cause rust and corrosion on your radiator system. The buildup of rust on the metallic parts in your radiator can cause clogging in the cooling lines and can also lead to leaks resulting to your car's poor performance. So it's better to use Prestone Radiator Protect because it provides protection against rust and corrosion, extending the life of your radiator system.

 If I'm currently using water for my radiator, should I flush the water first before replacing it with Prestone Radiator Protect?

For maximum protection against rust and corrosion in your radiator system and optimal use (having existing water in the radiator system may dilute the product), it is highly recommended to flush all water in the system and replace it with Prestone Radiator Protect.

 What if my car’s radiator system already has rusts?

Prestone Radiator Protect will remove rusts and will also minimize future accumulation. It will also provide additional lubrication to non-metallic components and prevention of future corrosion and cavitation.

 Can I use Prestone Radiator Protect to any car models?

Prestone Radiator Protect is compatible and can be used to any car models.

 What is the difference between Prestone Radiator Protect and Prestone Coolant?

Prestone Radiator Protect offers your radiator system excellent protection against rust and corrosion. The same with Coolant. But Prestone Coolant contains ethylene glycol hence you get added protection against overheating. So for better boilover protection and protection against rust and corrossion, use Prestone Coolant.

 If I am a currently using Coolant for my radiator, can I switch to Prestone Radiator Protect?

Prestone Radiator Protect is recommended over water as it gives anti-rust and anti-corrosion benefits that water can’t provide. To prevent overheating troubles while also protecting your car’s radiator from rust and corrosion, it’s best to keep using Prestone Coolant. But take note that it is not recommended to mix these two products because doing so can dilute the level of your coolant thus lessening its boilover protection.
