Blocks your radiator

Bought this after pulling the engine out of my old XF Falcon Ute and attempting to repair a hairline crack with JB Weld. It failed. Bought this product as I wasn't pulling the engine out again. It worked. Only problem, it also blocked the radiator cores and caused the head gasket to blow. Not recommended.

Sorry to hear the product blocked your radiator, while the product is formulated to be a one step, no draining required solution, the radiator and cooling system must be clean, free of scale and build up, as the product contains cleaning agents, that can dislodge scale and cause blockages, if this occurs, a radiator flush will provide a deep clean of the system, and remove the debris.
