Removal

1 Before removing a hose, drain the cooling system (see Chapter 1).

2 Use a screwdriver or small socket to


slacken the larger-bore hose clips, then slide them back along the hose and clear of theunion spigot. The smaller-bore hoses are secured by spring clips which can be expanded by squeezing their ends together with pliers (see illustrations). Caution: The radiator unions are fragile. Do not use excessive force when attempting to remove thehoses.

3If a hose proves stubborn, release It by rotating it on its union before working it off, If all else fails, cut the hose with a sharp knife then slit it at each union so that it can be peeled off in two pieces. Whilst this means renewing the hose, it is preferable to buying a new radiator.

4 The coolant pipe inlet union at the front of the cylinder block and the outlet union at the rear of the cylinder head can be removed by unscrewing the retaining bolts (see illustrations).

Installation

5 Slide the clips onto the hose and then work
the hose onto its respective union.
