K-Seal couldn’t be simpler to use. Just shake the bottle, add the fluid to your coolant system, and run your engine as normal. K-Seal’s unique formula will seek out holes and cracks, and permanently seal them, with no adverse impact on the efficiency of your engine cooling.

The Safe and Easy Way to Fix a Coolant Leak

The secret behind K-Seal’s ability to repair a coolant leak is down to its contents: a specially developed blend of chemical ingredients including ceramic microfibres and copper particles. When added to the cooling system the ingredients disperse and flow freely around the system suspended in the coolant. If coolant is leaking from the system, either externally (look for a puddle under the engine) or internally across the head to the cylinders, then K-Seal will follow it through the hole or crack and try to fix the leak.

Coolant System Sealer

Once the crack or hole has been located, the microfibres instantly begin to mesh together within the gap, building a seal literally fibre by fibre to stop the coolant leaking through the gap.

The particles in our K-Seal products are very precisely designed to be large enough to repair holes up to 0.635mm in size but deliberately small enough to never block any passageways or tubes within the cooling system, including those inside the heater core and radiator.

Once the microfibres have sealed and fixed the leak, a combination of exposure to either the external atmosphere or the gases within the combustion chamber and the heat within the cooling system and engine causes the K-Seal formula to cure.

This results in an extremely strong and permanent seal able to withstand even the high pressures from the combustion chamber. This is how K-Seal ULTIMATE is able to repair head gasket failures, even where the cooling system is being over-pressurised by exhaust gases entering the system.
