Rolls-Royce Corniche - Radiator Header Tank-To Remove, to Fit; Radiator-To Remove, to Fit

Rolls-Royce Silver Shadow & Bentley T Series
Workshop Manual
Radiator - To remove
1.
Drive the car onto a ramp.
2. Firmly apply the handbrake/parking brake
and remove the gear range thermal cut-out from the
fuseboard.
3. Drain the coolant as described in Cooling
system
- To drain, Section L1.
4. Slacken the worm drive clips and remove the
two top hoses and one bottom hose at the radiator.
5. Disconnect the cables from the coolant
probe in the header tank.
6. Disconnect the two heat exchange pipes, if
fitted, from the underside of the radiator. Fit
blanking plugs to prevent the ingress of dirt.
7. Disconnect the header tank steam escape
pipe and bleed hose from the header tank to the
radiator.
8.
Remove the four setscrews securing the fan,
or the four nuts holding the fan and viscious
coupling to the water pump pulley extension cone.
9. Slacken the tension on the drive belts.
10. Carefully withdraw the fan or, in the case of
the fan and viscous coupling, place these inside
the radiator cowl.
Take care not to damage the radiator matrix.
11. Support the radiator then remove the four
setscrews securing the assembly to the bonnet
hinge panels.
12. Carefully withdraw the radiator and header
tank.
13. Remove the fan or fan and viscous coupling
from the cowl.
Radiator - To fit
To fit the radiator, reverse the procedure given
for removal noting the following points.
1. Examine all hoses for deterioration and
renew any found to be unserviceable.
2. Fill the system with a clean coolant solution.
3. Check the level of concentration as shown in
Section
L1 - Coolant - To check. Correct the level
of concentration as necessary.

RADIATOR
Important - Cars with radiator cowlings
After re~lacement of the radiator a check must be
made for possible fouling of the fan blades on the
radiator cowling, using the following procedures.
4.
Check that a minimum clearance of 16 mm.
(0.630 in.) exists between the tip of the fan blades
and around most of the cowling.
A clearance of
9,5 mm. (0.370 in.) is acceptable at the lower
section of the cowling.
5. To check that engine.torque does not cause
the fan to foul the cowling, apply the
handbrake/
parking brake, set the engine onto fast idle by
pressing the accelerator and then start the engine.
6. Select
(D) Drive and (R) Reverse. Listen for
any catching of the blades on the radiator cowling.
No attempt must be made to increase engine speed
above that of fast idle.
7.
Choose an open stretch of dry road. When the
road is free from any potential danger, accelerate
the car sharply from a stand still position and
listen for fouling of the blades on the cowling.
Radiator header tank - To remove
(radiator in the car)
The header tank is supported on three brackets
attached to the top face of the radiator.
1. Remove the radiator filler cap, open the
drain tap and drain sufficient coolant to empty the
header tank; approximately
2 litres (3.5 pints) into
a clean container.
2.
Slacken the worm drive clips and remove the
hose between the header tank and the radiator.
3. Remove the header tank steam escape pipe
at the header tank connection.
4. Disconnect the cables from the coolant probe.
5. Remove the three nuts, bolts and washers
from the supporting brackets and remove the
header tank.
