Pour CRC FiberLock® directly into your radiator for a fast, permanent repair. CRC FiberLock® works on head gaskets, engine blocks, intake gaskets, cylinder heads, freeze plugs, heater cores and coolant leaks and features a powerful 3-tier formal compatible with all types of antifreeze. Repairs leaks using three unique technologies: Military-Strength Fibres – Proprietary lightweight fibres with a high strength-to-weight ratio make an interlocking web-like weave over the breach, ensuring a permanent, multi-layer, impenetrable repair. Nano-Technology A = A typical block repair product attempting to adhere to a metal surface, but the particles are too large leaving room for leaks. B = Fiberlock® with nano-particles making a stronger more solid bond to the metal and its own particles. Cool-X Conditioner – Cool-X Conditioner circulates in the cooling system for lower operating temperatures and improved heat transfer long after the repair is made.
