recommended cold level is 3/8 inch (10mm) below the horizontal
moulded seam running around the tank, with the lowest accept-
able level being 1 inch (25mm) below the seam.
If topping up is required, ensure that the coolant is fully cold
before slowly unscrewing the filler cap and allowing any remain-
ing pressure to escape before finally removing the cap.
In order to maintain protection from freezing damage and
metal corrosion, use only an approved coolant mixture (see
below) to top up the header tank to the 'full' level. Refit the cap,
and turn clockwise until the tab on the cap engages a detent, at
which position an abutment prevents any over-tightening.
NOTICE
If the cap is removed when the engine is warm, the
coolant may boil and a small coolant loss may occur. The com-
pletely cold header tank level should be checked at the first
subsequent opportunity.
Cooling Fans: Two cooling fans are fitted above the front mounted
radiator in the air outlet duct and will run at either half or full
speed, dependant on coolant temperature and air conditioning
system demands. The fans will also run as a protection meas-
ure, if the on-board diagnostic system identifies certain types
of engine fault.
In addition to the radiator fans, a further fan is fitted over
the right hand rear wheelarch to help control air temperature
within the engine bay. This fan may be triggered any time the
vehicle is stationary, with engine idling or stopped, dependent
on coolant temperature.
In order further to control heat soak effects after engine shut
down, a coolant re-circulation pump may be heard running,
possibly supplemented by the cooling fans, anytime during a 10
minute period after switching off the ignition.
WARNING
Keep hands, tools and clothing away from the radiator or engine
bay cooling fan areas, as personal injury could result from the
fans starting up without warning, even with the ignition off.
At service intervals, the air duct and matrices of the engine
cooling radiator and a.c. condenser should be checked externally
for clogging by insects, leaves or other debris, and if necessary,
a water jet used to clear the finning. Take care not to damage or
distort the delicate fins of the radiator or the cooling perform-
