Leaky V-Type Radiator: Repairing H-Type Valve or Screw Connection in Heating System

Would someone be able to tell me how to start repairing a leaking radiator? From what I read, it is a V type radiator. It is connected from the bottom with an H-type valve. It leaks either on this valve or on a screw connection. Tightening more resulted in more leakage. Please help me quickly because I am currently sitting without heating . ps. How to properly tighten this radiator?

Is there a leak between (on your "nose") the valve and the radiator?

If you tighten harder and the water flows harder, you will need to install a new O-ring or gasket (what's there). You have to disconnect the heater and replace it.

You can seal with modeling clay quickly and temporarily, and then make a repair that requires unscrewing the radiator.

on my nose the situation looks like this. They are from above
1. Heater
2. Gold nut (so thin) with thread directly adjacent to the radiator
3. A thick silver cap between the valve in the shape of the letter H and with the inscription H and the gold cap from point 3.
4. H-type valve

The leakage to my eye is between 2 and 3 or between 3 and 4

In other words, with a high degree of probability, if you use a wide screwdriver to set the notches on the valve (both) horizontally (closed position), water will only leak from the radiator. The rest of the installation can be used after adding water.
There should be a vent on the radiator - after closing the valve, check that water is leaking from the vent. If it is leaking from the breather, you have turned it off incorrectly.
Take photos.

If you have turned correctly and the water stops leaking after a while, you have time to think carefully what to do next.
Take pictures of the connector.

I took a photo. A little overexposed, but it's from the phone. https://obrazki.elektroda.pl/5375055000_1329776623.jpg. The valve on the right is leaking. Unfortunately, setting the adjustment in the horizontal position does not help. I can turn it freely in any direction. For now, the heating will remain off.

After setting the valves to 9-15, you put some water collecting vessels and slowly unscrew the screws. After emptying the radiator of water, unscrew it completely, remove the radiator and replace with both sealants. You put on the radiator and tighten it sensitively. You open one valve completely, and you fill the radiator with the other, with the venting turned on. If water seeps from the valves, tighten the flare nut slightly.

are these sealants some o-rings? What to ask for in the store?

There may be o-rings, but there may be flat gaskets. Since the heating element does not heat up anyway, close the valves and let the water flow out. After unscrewing it you will see what is there.

problem solved. thanks for the help
