As a precaution, every week when the engine is completely

COLD, and without disturbing the filler cap, check that the level

of coolant in the translucent tank is between the 'FULL' and

'LOW' marks moulded on the front of the tank. If topping up is

required, wait until the coolant has fully cooled before turning the

cap a quarter turn counterclockwise and allowing any remain

ing pressure to escape. Only then may the cap be completely

unscrewed.

In order to maintain protection from freezing damage and

metal corrosion, use only an approved coolant mixture (see

below) to top up the tank to the 'FULL' mark. Refit the cap, and

turn clockwise until the leg on the cap locates in the slot at the

front of the tank.

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 below the radiator in

the air intake duct. The fans are energised at high coolant tem-

peratures, or when the air conditioning (if fitted) is selected. The

fans will also run if certain types of engine fault are detected, and

may operate during a 20 minute period following ignition switch

off to prevent 'hot soak' boiling. An electric coolant circulation

pump may also be heard running during this period.

WARNING:

Keep hands, tools and clothing away from the radiator

cooling fan area, as personal injury could result from the

fans starting up without warning.

At service intervals, the air ducts and matrices of the engine

cooling radiator, a.c. condenser, oil coolers and chargecooler (if

fitted), should be checked for accumulation of insects, leaves

or other debris, and any necessary measures taken to clear the

finning. Take care not to damage or distort the delicate fins of the

radiator cores, or the cooling performance will be degraded.
