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. This results in an extremely strong and permanent seal able to withstand even the high pressures from the combustion chamber. It works well for pinhole or other teeny-tiny leaks.
This truck does not have an expansion bottle directly connected to the radiator, it is just pressure relief. It is surely light brown on the napkin because of dirt and rust/corrosion. It does not smell weird with cold air or when the heat is on a lower fan setting. This shows how proper maintenance is important and can save you money, even if things aren't right.Why We Like This:
- Works good as a leak stop can,quick fix
- More overheating and high temp conditions

It will stop water leaks but it does not prevent your car from overheating. It will not pressurize the leaking cylinder.
It is something that you pour into the radiator/ cooling system that will stop leaks of antifreeze (liquid) from the cooling system. It is good for any leak as it travels throughout your car and seals any leak it comes into contact with. The color of this liquid is bronze.Why We Like This:
- Circulates through your whole system without exiting somewhere
- Worked on a leaking intake manifold gasket
- Copper dust/ ceramic slurry for head gasket leaks
