Can that workshop repair and vehicle downtime be avoided?

The solution could be in the big blue bottle. With over 1 million bottles sold in the UK alone, K-Seal HD permanent coolant repair is the brand that motor stockists recommend with confidence to their customers with buses, coaches and HGVs. Why?

K-Seal HD:

  • Fixes most leaks in all types of water cooled engine including cracked heads, head gasket failures, cracked blocks, radiators, heater cores and water pumps.
  • A repair made with K-Seal HD is permanent, guaranteed for the lifetime of the engine.
  • Unlike inferior coolant products, K-Seal HD mixes with all types of antifreeze and coolant. There’s no need to drain or flush the system before or after treatment.
  • K-Seal HD is easy to use. Shake the bottle; add it to the cooling system and go.

K-Seal HD can be used in the workshop, on the road or on site so your vehicle can be put back into service almost immediately, avoiding expensive downtime. Always have a bottle on standby for every vehicle!
