SERVICE INSTRUCTION:
WARNING: Cover the engine coolant expansion tank pressure cap with a thick cloth to prevent the
possibility of scalding. Release the cooling system pressure by slowly turning the engine coolant expansion
tank cap a quarter of a turn. Failure to follow this instruction may result in personal injury.
CAUTION: The engine cooling system must be maintained with the correct concentration and type of antifreeze solution to prevent corrosion and frost damage. Failure to follow this instruction may result in damage
to the engine.
CAUTION: Engine coolant will damage the paint finished surfaces. If spilt, immediately remove the coolant
and clean the area with water.
CAUTION: Never remove the engine coolant expansion tank cap under any circumstances while the engine
is operating. Failure to follow this instruction may result in damage to the engine.
CAUTION: Since injury such as scalding could be caused by escaping steam or coolant, make sure the
vehicle cooling system is cool prior to carrying out this procedure.
CAUTION: Be prepared to collect escaping coolant.
1. Remove the engine coolant expansion tank pressure cap.
2. Set a vernier caliper to 50.70mm.

3. Check the dimensions of the engine coolant expansion tank threaded neck in the two positions shown.
• If the dimensions across the centerline neck are less than 50.70mm, go to Step 5.
• If the dimensions across the centerline of the neck are 50.70mm or greater, go to Step 4.

4. Visually inspect the sealing bead on the engine coolant expansion tank neck to check for damage.
• If the sealing bead is damaged, go to Step 5.
• If no damage is found:
• Install a new engine coolant expansion tank pressure cap.
• Top up the engine coolant to the MAX level mark.
• Run the engine up to normal operating temperature, allowing the electric cooling fan to operate at least
once without problem before releasing the vehicle.
• Switch the engine OFF.

5. Install a new engine coolant expansion tank and a new coolant pressure cap (see TOPIx Workshop Manual section
303-03: Engine Cooling - Engine Coolant Expansion Tank).
6. Run the engine up to normal operating temperature, allowing the electric cooling fan to operate at least once without
problem before releasing the vehicle.
7. If engine coolant loss continues and/or an engine overheat message is displayed on the Instrument Cluster following
completion of this Technical Bulletin, further diagnosis and repair will be necessary (see TOPIx Workshop Manual
section 303-03: Engine Cooling - Cooling System Draining, Filling and Bleeding). To be performed as a separate
claim.
