TOPPING UP THE COOLANT

WARNING

Never remove the filler cap when the engine is hot - escaping steam or scalding water could cause serious personal injury.

Unscrew the filler cap slowly, allowing the pressure to escape before removing completely.

WARNING

Avoid spilling antifreeze onto a hot engine - a fire may result.

WARNING

Antifreeze is poisonous and can be fatal if swallowed - keep containers sealed and out of the reach of children. If accidental consumption is suspected, seek medical attention immediately.

WARNING

If the fluid comes into contact with the skin or eyes, rinse immediately with plenty of water.

CAUTION

When traveling in places where the water supply contains salt, always make sure you carry a supply of fresh (rain or distilled) water. Topping up with salt water will cause serious engine damage.

CAUTION

The use of non-approved antifreeze will have an adverse effect on the engine cooling system and; therefore, engine durability.

CAUTION

Antifreeze will damage painted surfaces; soak up any spillage with an absorbent cloth immediately and wash the area with a mixture of car shampoo and water.

Top up to the upper level indicator mark of the COLD FILL RANGE, located on the side of the expansion tank. Use only a 50% mix of water and approved antifreeze. See LUBRICANTS AND FLUIDS.

The specific gravity of a 50% antifreeze solution at 68°F (20°C) is 1.068 and protects against frost down to -40°F (-40°C).

Antifreeze contains important corrosion inhibitors. The antifreeze content of the coolant must be maintained at 50% ± 5% all year round (not just in cold conditions). To make sure that the anti-corrosion properties of the coolant are retained, the antifreeze content should be checked once a year and completely renewed every ten years, regardless of distance traveled. Failure to do so may cause corrosion of the radiator and engine components.

NOTES

In an emergency - and only if the approved antifreeze is unavailable - top up the cooling system with clean water, but be aware of the resultant reduction in frost protection. Do not top up or refill with conventional antifreeze formulations. If in doubt, consult a qualified technician.

Make sure the cap is tightened fully after top up is completed, by turning the cap until the ratchet cap clicks at least three times.
