Hi-Gear HG9041 is a cermet sealant that is perfect for eliminating leakage of additional gaskets (when transferring engines to gasoline of the 76th grade).

Using this tool, it is possible to repair (weld strength) cracked heads and cylinder blocks of aluminum or cast iron, to eliminate leaks of radiators and furnace heaters made of copper, aluminum, plastic and composite materials. The substance contains the finest ceramic fibers, which provide additional strength and allow the repair of large damages.

The principle of the sealant's work consists in getting this substance into cracks, through which the liquid leaks and the formation of the cermet plug, which is expandable during the polymerization process.

High coefficient of temperature expansion (close to metals) and elasticity guarantee the duration of the effect obtained. As established by experts from the United States, cermet sealant in its characteristics is not worse than all known Metallic Radiator & Block Seal.

Question: How to fix a drip leak in the engine (in places of rubber seals), considering that the damage appeared at the junction of dissimilar materials (rubber and metal)? Metal or metal-ceramic sealant?

Answer: There are two options.

In the event that coolant replacement is planned in the near future, it is better to choose Hi-Gear HG9037 with pre-flushing of the system by 7-minute flushing of the HG9014, which is used for preventive purposes on gasoline and diesel engines at ambient temperatures of -30 ° C to + 40 ° FROM.

If the antifreeze has already been replaced, it is necessary to choose the cermet sealants. The substance can be added to coolant and water.
