Check the tightness of the hose clamps or new hoses after several hundred kilometers of driving.
Fill the cooling system if necessary.
Removal and replacement
1. Before starting work, check that new hoses are available together with new clamps if necessary. It is recommended to replace the clamps together with the hoses.
2. Drain the coolant from the cooling system (see subsection 2.4.5), while preserving the coolant if it is suitable for secondary use.
3. Lubricate the hose clamps with oil if they are damaged by corrosion.
4. Release the clamps from the appropriate hoses. Three types of hoses are used; screw, spring and tension.
5. Screw clamps are released by turning their screw counterclockwise. Spring clamps are released by squeezing their tabs and pulling them off the hose nozzle. Tightening clamps are not reusable and are best cut with metal shears or wire cutters.
6. Remove the wires and hoses that are attached to the hose being removed. Just in case, try to remember the previous location of all the elements.
7. Use a circular motion to remove the hose from its connector. Be careful not to damage the connectors on delicate components like the radiator. If the hose is firmly stuck, it is often best to cut it off with a sharp knife, but again, be careful not to damage the connector.
8. Before installing a new hose, lubricate the fittings with soapy water or other rubber lubricant. Do not use oil or grease that may corrode the rubber.
9. Install the hose clamps onto the ends of the hose, then install the hose onto the fittings.
10. Fix the hose in this position and then secure the hose clamps.
11. Fill the cooling system.
12. Start the engine and check for leaks.
