CRC FiberLock Head Gasket & Block Repair
Permanent repair solution for cooling system leaks
CRC FiberLock Head Gasket & Block Repair is a revolutionary pour-and-go formula that permanently fixes leaks in head gaskets, engine blocks, intake gaskets, cylinder heads, freeze plugs, heater cores and coolant leaks. This advanced 3-tier formula is compatible with all types of antifreeze.
Three Unique Technologies
Military-Strength Fibres
Proprietary lightweight fibres with a high strength-to-weight ratio create an interlocking web-like weave over the breach, ensuring a permanent, multi-layer, impenetrable repair.
Nano-Technology
Unlike typical block repair products with particles too large to properly seal, CRC FiberLock uses nano-particles that make a stronger, more solid bond to metal surfaces and create superior adhesion between particles.
Cool-X Conditioner
Circulates continuously in the cooling system for lower operating temperatures and improved heat transfer long after the repair is completed.
