Avoid costly repair bills and downtime with K-Seal HD K5516 Coolant Leak Repair; the simple, permanent solution to cooling system leaks.
K-Seal HD fixes most leaks in water-cooled engines and is designed specifically for HGVs, tractors, heavy plant and other commercial vehicles. It is compatible with all coolant system additives and kinds of antifreeze, meaning you can use K-Seal HD with confidence at all times.
With K-Seal HD there’s no need to take a commercial vehicle off the road – just apply and run the engine as normal. K-Seal HD’s scientifically-tested formula, containing ceramic microfibers and copper particles, will seek out cracks and holes and provide a guaranteed repair for the lifetime of the engine.
So what was the conclusion?
“The test data shows that K-Seal is capable of sealing 0.635mm diameter holes and 0.254mm wide by 12.7mm long slots satisfactorily in accordance with ASTM D3147.”

It was also confirmed that there was no presence of particles, gumming or gelling in the 0.85mm mesh tests. Meaning there’s no risk of K-Seal causing other problems in your engine when applied – simply shake, pour and go!
The only standard in the world that specifies what a product that seals engine coolant leaks should and should not seal is called “Standard Test Method for Testing Stop-Leak Additives for Engine Coolants”, or ASTM D3147 for short.
As of 2015, the only independent academic facility in the UK or USA that has the ability to test products to ASTM D3147 is Brighton University Engineering Division which, in a joint project with K-Seal which was supplemented by funding from the government, has been able to commission, build and run the necessary test equipment.
A test rig that simulates an engine’s cooling system has to be built to specific measurements set out in the standard’s conditions. It has to be controlled extremely precisely in order for tests to be repeated with the specified conditions replicated exactly the same way every time.
For instance, temperatures, water flow and pressure rates need to be exactly the same, and holes and slots need to be the same sizes. In fact, the holes have to be prepared by a specialist engineering firm who can guarantee accuracy at such a tiny diameter.
An ASTM D3147-classified product must be able to:
An ASTM D3147 classification means you can use K-Seal safe in the knowledge that it does exactly what it says on the bottle: seal holes in your coolant system and cracks in your head gasket, with ease. That means stopping leaks and preventing costly repairs to get you back on the road, fast.
