An over-heating engine caused by a leaking radiator on a deserted stretch of road is a motorist’s worst nightmare, but now there’s an instant fix.
It’s called K-Seal and it’s a relatively inexpensive solution to coolant leaks under the bonnet and, what’s more, it can provide a permanent repair to some problems.
K-Seal will permanently repair and fix most leaks in the radiator or radiator casing up to a maximum size of 0.7mm Ð larger holes or cracks will require an epoxy putty. And, in addition to the radiator, it will also repair leaks in the head, head gasket, block, heater matrix, freeze plug and water pump casing, which makes it ideal for older engines, where the owner does not want to incur a big expense on major repairs.
K-Seal is simple to use – a quick shake, then pour and go. No need to drain or flush the system. No need to worry about what type of anti-freeze or coolant is in the cooling system.It’s suitable for use with all water-cooled engines, including cars, motorbikes, commercial vehicles, heavy plant, agricultural machinery, marine engines and generators.
The secret behind how K-Seal can repair a coolant leak so easily and effectively is down to a specially developed blend of chemical ingredients, including ceramic micro-fibres and copper particles.When added to the cooling system, the ingredients disperse and flow freely around the system suspended in the coolant.But if coolant is leaking from the system, either externally or internally across the head to the cylinders, then K-Seal will follow the coolant through the hole or crack and begin fixing the coolant leak.
What happens is that the micro-fibres start to mesh together within the crack or the hole, building a seal literally fibre by fibre.In reality, this takes place almost instantly once K-Seal has reached the leak. The particles in K-Seal are very precisely designed to be large enough to repair holes up to 0.7mm in size, but deliberately small enough to never block any passageways or tubes within the cooling system, including the heater core and radiator.
Once the micro-fibres have sealed and fixed the leak, a combination of exposure to an atmosphere, either the external atmosphere or the gases within the combustion chamber, together with the heat within the cooling system and engine, causes the K-Seal formula to cure.ÊThis results in an extremely strong and permanent seal able to withstand even the high pressures from the combustion chamber. This explains how K-Seal is able to repair head gasket failures, even where the cooling system is being over pressurised by exhaust gases entering the system.
