Opel Corsa B 1993–2000 Service and Repair Manual: Cooling system hoses - disconnection and renewal

1. If the checks reveal a faulty hose, it must be renewed as follows.

2. First drain the cooling system. If the coolant is not due for renewal, it may be re-used if it is collected in a clean container.

3. To disconnect a hose, use a screwdriver to slacken the clips, then move them along the hose, clear of the relevant inlet/outlet union.

Carefully work the hose free. While the hoses can be removed with relative ease when new, or when hot, do not attempt to disconnect any part of the system while it is still hot.

4. Note that the radiator inlet and outlet unions are fragile; do not use excessive force when attempting to remove the hoses. If a hose proves to be difficult to remove, try to release it by rotating the hose ends before attempting to free it. If all else fails, cut the hose with a sharp knife, then slit it so that it can be peeled off in two pieces. Although this may prove expensive if the hose is otherwise undamaged, it is preferable to buying a new radiator.

5. When fitting a hose, first slide the clips onto the hose, then work the hose into position. If clamp type clips were originally fitted, it is a good idea to replace them with screw type clips when refitting the hose. If the hose is stiff, use a little soapy water as a lubricant, or soften the hose by soaking it in hot water.

6. Work the hose into position, checking that it is correctly routed, then slide each clip along the hose until it passes over the flared end of the relevant inlet/outlet union, before tightening the clips securely.

7. Refill the cooling system.

8. Check thoroughly for leaks as soon as possible after disturbing any part of the cooling system.
