Note: See Warnings given in Chapter 1 this Section before you begin working.
1. If, as a result of the checks described in Section 1, You have identified a defective hose, replace it as follows. First, drain the liquid from the cooling system (see Section 1); if the antifreeze is not being replaced, collect the drained coolant in a clean container. Although the hoses are easier to remove while they are hot, do not attempt to disconnect any part of the system while it is still hot (see Chapter 1).
2. To disconnect the hose, loosen the clamps with a screwdriver, then slide them along the hose away from the end. Carefully remove the ends of the hose from the fittings. If the hose has spring-wire or crimp-type clamps, it is recommended to replace them with screw-type clamps when installing a new hose.
3. Please note that the radiator hoses are fragile; do not apply too much force when trying to remove the hoses from them. If the hose is stuck, try to free it by twisting its end on the branch pipe. As a last resort, cut the hose, then cut the stuck end lengthwise into two parts and remove them from the branch pipe.
4. When installing a new hose, first put the clamps on it, then put the hose on the nozzles (see photo). If the hose has hardened somewhat, use a soap solution as a lubricant or soften the end of the hose by placing it in boiling water. Be careful not to scald yourself.
5. Fully install the ends of the hose onto the appropriate fittings, ensure that the hose is correctly routed relative to other components, then slide the clamps along the hose to the attachment points (behind the widened sections of the pipes) and clamp them securely.
6. Fill the system with coolant (see Section 1).
7. Check the system thoroughly for leaks.
