EMERGENCIES
CAUTION:
Immediate action is required if the engine overheats. This can be indicated by the
temperature gauge needle moving over to the "H", by steam escaping from under the
bonnet, a loss of power or a loud knocking or pinging noise. Continued driving EVEN
FOR A SHORT TIME could cause a fire or car
Pull out of the traffic as soon as possible and stop the car. Leave the engine idling and
the park brake applied while you get out and check that the cooling fan is working.
CAUTION:
Do not open the bonnet if you can see or hear steam or coolant escaping from the engine

rtment. Wait until no steam or coolant can be seen or heard before opening the

If the fan is working and the temperature gauge needle has not returned to its normal
position within a few minutes STOP the engine and remove the ignition key. Look for
leaks at the radiator hoses and connections, heater hoses and connections, radiator
and water pump. Take care when checking these areas as they will probably still be hot.
If you find a major leak or other problems that may have caused the engine to overheat,
do not run the engine until these problems have been corrected.
If you do not find anything wrong then you should check the engine coolant level, for
V6 or V8 as appropriate.

Turn the coolant dipstick cap a quarter of a
turn anti-clockwise and pull out the dipstick.
When the engine is cold the coolant level
should be at or above the lower triangle
driven and the engine is at normal operating
temperature, t h e
somewhere between half full and the
MAXIMUM triangle mark. If the coolant
level is correct, replace the dipstick and
turn the cap a quarter of a turn clockwise to
secure. If the level is too low, proceed as
follows.
CAUTION:
Do not remove the radiator cap if the
engine and radiator are still hot. Scalding
fluid and steam can be blown out under
pressure which could cause serious burns.
When the engine has cooled
check the radiator level as follows.
Cover the radiator cap with a thick cloth and turn slowly anti-clockwise (without pressing
down) until it reaches a "stop". This is the pressure relief stop, which allows any
remaining pressure (indicated by a hissing sound) to
cap and continue turning it anti-clockwise until it can be removed. Then remove the
coolant dipstick. With the radiator cap OFF, top up the coolant dipstick tank if required.
Remember to ensure the dipstick is secure after filling. Then, WHILE THE ENGINE IS
IDLING, top up the radiator (if required) and replace the radiator cap.
