Note: Before starting the procedure, read the warnings contained in paragraph 1 of this chapter. Do not attempt to disconnect hoses on a hot engine to avoid burns.
1. The number, dimensions and purpose of hoses, depending on the engine model, may be different, but the principles of working with them are the same. Before starting work, make sure you have the necessary hoses and clamps on hand for replacement. It is good practice to replace the clamps every time a hose is removed/installed.
2. First drain the cooling system as described in chapter 1A or 1B. If the fluid is not drained for replacement, it can be drained into a suitable clean canister.
3. Before disconnecting the hose, remember its laying under the hood. Loosen the clamps and slide them along the hose away from the connecting pipe. The hose moves easily when new. old can "dry up".
4. Remove the hose by turning it on the fitting. Pay attention to that. that the radiator connections are very fragile, so do not use excessive force when disconnecting the hoses. If the hoses are stuck tightly, it is cheaper to cut them off than to break the radiator. However, first make sure you have a new hose.
5. When installing the hose, first put the clamps on it, then put the hose on the nozzles. Some hoses have installation marks - follow them.
6. Before tightening the clamps, make sure that the hose is properly laid, slide the clamps onto the nozzles, passing through the thickenings on the ends of the nozzles.
7. Fill the system with coolant as described in chapter 1. Start the engine and immediately check for leaks.
8. After several hundreds of kilometers, check the reliability of the hose connections again.
