Use with Prestone Coolant/Antifreeze for a complete flush and fill solution and 10-year guarantee

It?s designed to be used to flush the radiator, powering through dirt, rust, and grime to extend the life of internal parts within the cooling system.

In the past, water has been used to flush cooling systems before adding fresh coolant/antifreeze. But it?s not very effective at removing stubborn deposits and corrosion, and can actually contribute to the problem due to limescale build up.

Recognising this problem, Prestone developed Cooling System Flush as a means of cleaning the cooling system in between coolant/antifreeze changes.

Cooling System Flush gets to work instantly, removing tough deposits and dirt from the cooling system to ensure maximum performance and efficiency.

How to use:

Using Cooling System Flush is easy, and you can apply it at home as part of a scheduled cooling flush. 

1.  Make sure the engine is cool. Drain the system and dispose of it according to local regulations.
2. Pour Prestone Cooling System Flush into expansion tank, top up with water to correct level and run engine at idle for 45-60 mins

Drain system, flush with water and add Prestone coolant/antifreeze to correct level. Check coolant level regularly and top up as necessary.
