Great Stuff.

This stuff saved my car. Bought a bottle from takealot, but didnt think much of it, till the day after putting it in the car. My gasket was starting to go, as I was loosing water & car was overheating, struggling to idle. Put this in with antifreeze & topped of with water. I idled car 30 mins & extra 2 liters water, next morning, coolant was good, went for drive & no problems, even idling is back to normal. Magic in a bottle.
