ideal for quarterly or yearly car service. i usually empty the bottle in the radiator and drive like 100km (town and back for me) to let the flush go through all out the channels and clean it. then after replace my coolant. works wonders for me great value at that price

Really helps clear your radiator and save you from problems later on, especially in older cars like VW

Good product,works like a charm,hence beed to warm you engine and have good warm sirculating water,then add,works at it best,run the engine for an hour,or more,then drain water,loosen all dirt and rust,do it twice in a month,and your cooling system will thank you all the way.

I had a leak and weekly topped up with borehole water with a lot of limescale which resulted in overheating. This cleaned the engine out quickly and sorted the problem.
