19 . When the engine is working, in particular under high speed or high load, do not
turn the ignition switch off suddenly. Allow it to run 3-5 minutes at low speed
before stopping, to ensure even radiation.
20 . Sealant is widely used across the engine. It is designed to provide sufficient
sealing. Pay special attention to the volume, location and interface of the sealant.
Insufficient application will cause leakage, while excessive application or spillover
will block or narrow the water or oil channel.Therefore, it is important to apply
the sealant properly.

21 . If necessary, gently knock the parts with a wooden/rubber hammer or similar
tool, in order to damage the sealant interface. Or slightly insert a flat, smooth
and thin sealant scraper into the interface, without damaging it.
22 . Clear the surface with a sealant scraper or wire brush. Ensure the surface is
even and smooth, free of grease and impurities. Remember to remove the sealant
in the assembly holes and threaded holes.
23 . Evenly apply the sealant across the specified diameter around the assembly
hole. Remove the soft sealant. Install it to the specified position within 15 minutes,
when the sealant is wet. During installation, do not apply the sealant onto any
unnecessary position. After installation, wait for the hardening process of the
sealant, which will take about 1 hour. Do not grease or wet the applied surface
or start the engine during the period.
