Note: See warning in paragraph 1 this chapter.
1. If as a result of the check described in chapter 1, it turned out that any hose is defective, then it must be replaced as follows, (see fig. 3.1).
2. First of all, drain the liquid from the cooling system (see chapter 1). If there is no need to change the coolant, drain it into a clean container for later use.
3. To disconnect the hose with pliers, release the elastic clamps (or use a screwdriver to loosen the clamp screws), and then pull the hose off the connection fitting. Carefully remove the hose from the nozzle. New hoses come off easily, but old ones can stick.
4. If the hose is stuck, try twisting it before removing it. Try gently prying off the end of the hose with a blunt tool (e.g. with a flat-bladed screwdriver), without much effort. Be careful not to damage the fittings or hoses. Please note that the radiator pipes are fragile and do not use much force when removing the hose. If the hose still cannot be removed, cut it with a sharp knife, and then make a cut along the axis of the nozzle to remove the rest of the hose from it. You will need to purchase a new hose, but this is preferable to purchasing a new radiator. However, first make sure that the hose you need is on sale.
5. When installing the hose, first tighten the clamp on it, and then put the hose on the nozzles. If it's tight, use soapy water or heat the hose in boiling water, but don't scald yourself.
6. Push the ends of the hose onto the nozzles and check that it is correctly installed and routed. Pull each clamp through the hose until it is next to the socket flare, then tighten securely.
7. Fill the system with coolant (Chapter 1).
8. Immediately after removing and installing any of the system components, carefully check for leaks.
