How to use K-Seal HD
K-Seal HD can be used in the workshop, on-site, and even on the road. K-Seal HD’s unique formula can be used in hot or cold engines, simply by shaking the bottle and pouring the fluid into your vehicle’s radiator or header / expansion tank.
K-Seal HD will circulate harmlessly within your engine’s coolant until it locates a crack or hole, where it will coagulate and cure, forming a permanent seal. There’s no need to flush or clean your cooling system after use – just run your engine as normal.
ImportantPlease use extreme caution when working on a hot cooling system as hot coolant and gases could cause injury. If in doubt please consult a qualified mechanic.
