2. Drain the cooling system as described in Chapter 1. Keep the liquid if it is suitable for further use. If hose clamps are corroded, apply a small amount of well-penetrating oil to the clamp.
3. Loosen the hose clamp. Three types of clamps are used: worm type, spring and "canning" type (like in a sardine can). Worm drive clamps are loosened by turning the screw counterclockwise. The spring clamp is loosened by compressing the legs with pliers, while moving the clamp from the end of the hose. "Canning" Clamps are not used multiple times and are best cut with wire cutters or metal shears.
4. Unfasten any wires, cables, or other hoses that may be attached to the hose to be removed. Make notes, if necessary, to reinstall them correctly.
5. Remove the hose from the handpiece with a twisting motion. Be careful not to damage the ends on fragile parts such as the radiator or thermostat housing. If the hose is tight at the end, it is best to cut it off with a sharp knife. However, be careful not to damage the ends.
6. Before installing a new hose, lubricate the ends with soapy water or a suitable rubber lubricant to facilitate installation. Do not use oil or grease that may attack the rubber.
7. Install hose clamps on the ends of the hose, then put the hoses on the nozzles. Reinstall the hoses and tighten the clamps.
8. Fill the cooling system as described in Chapter 1. Start the engine and make sure there are no leaks.
9. After several hundred kilometers, check the tightness of the hoses.
10. Add coolant if necessary (see "Weekly check").
