Removal
1 Drain the cooling system as described in
Chapter 1.
2 Refer to Chapter 11 and remove the
bonnet.
3 Slacken the two retaining clips and
completely remove the radiator top hose.
4 If the bottom hose was not removed for
draining, slacken the retaining clip, using a
long thin screwdriver, and pull the hose off the
radiator outlet.
5 Undo and remove the bolts and nuts
securing the radiator upper support bracket to
the fan cowling and thermostat housing. Lift
away the bracket (see illustration).
6 On later 1275 cc engines (except
carburettor engine Cooper models)
disconnect the wiring connectors at the
auxiliary cooling fan thermostatic switch in the
bottom corner of the radiator.
7 At the base of the radiator undo and
remove either the long through-bolt or the two
short bolts (depending on model) that secure
the lower support bracket to the engine
mounting (see illustration). If necessary
remove the front grille panel as described in
Chapter 11 to provide greater access.

wanting to remove the radiator,
bear in mind that minor leaks
can often be cured using a
radiator sealant with the radiator in situ.
