Head Gasket & Block Repair

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 formula compatible with all types of antifreeze.

Repairs leaks using three unique technologies:

1. 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.

3. Nano-Technology: A typical block repair product attempts to adhere to a metal surface, but its large particles leave room for leaks. Fiberlock® with nano-particles makes a stronger, more solid bond to the metal and its own particles.

3. 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.
