Product Description

Stay Cool is a coolant system additive designed to improve heat transfer allowing for a faster warm up and better cooling (up to 15 degrees C reduction in engine temperature). Stay cool is also an anti corrosive agent suitable for use in all engines. Does not contain ethylene glycol but we recommend that a fresh 25% antifreeze solution is used with Stay Cool to ensure better heat transfer.1 litre bottle treats 30 litres of coolant.
