Hi All,
I noticed a little bit of water between the cylinders

the problem was in the ring that is installed in the tube between the cylinders, through which the coolant passes
O-Ring 21.5x2 91310-KE8-003 -2ps
I searched for information for a long time on how to replace the O-rings
it turned out to be simple,
1 - remove the retainer, use a screwdriver, carefully move the tube and take out the ring (the old one turned out to be hard and I couldn't remove the whole one)
2- put on a new ring, before that lubricate it with silicone and prepare 2 threads

3 - lie down on the tank and carefully put on the ring with both hands and take out the thread

4 - using a screwdriver, carefully push the stopper and push the tube into the cylinder.
5 - same with the second ring
I took the first ring off and on for about an hour, the second one for 2 minutes
