Hose replacement
1. With the engine cold, remove the radiator filler cap.
2. Drain some of the coolant (to replace the lower hoses, all fluid must be drained).
3. Remove clamps (wire clamps for this must be compressed with pliers).
4. Carefully remove the hose from the appropriate fitting by turning it (if necessary, carefully cut the hose with a razor blade so as not to damage the surface of the nozzle).
5. When installing, dip the end of the hose into the coolant, put on the clamp and put the hose on the pipe.
6. Secure the hose with a clamp, the clamp should be about 6 mm from the end of the hose, which should be behind the convex part of the nozzle.
7. Fill with fluid and warm up the engine, watching for leaks.
