Disconnect the battery negative terminal.
Release the hose clamp and remove the
radiator bottom hose to enable the cooling
system to be partially drained, so that coolant
level is below the thermostat housing, refit the
hose and secure in position with the hose
clamp.Remove the plenum chamber (see Plenum
Chamber, remove and refit).
Remove the ram housing (see ram housing

FUEL INJECFION SYSTEMFor 1989 model year, the EFI system has a Lucas
14CU electronic control unit. This is a development
of the 
13CU used on 3.5 litre vehicles.
In most respects the 14CU works in the same way
using the same engine components, it does
however have additional capacity, enabling it to
control fuel tank vapour purging and air
conditioning.
Condenser fansIt should be noted that under high coolant
temperatures, when the engine is switched off, the...
