rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

For more information, refer to ªMAIN 12 CAUSES
OF OVERHEATINGº, EC-SR-288.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA
section (ªChanging Engine Coolantº, ªENGINE MAINTENANCEº). Also, replace the engine oil.
1)Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA section (ªAnti-freeze Coolant Mixture Ratioº,
ªRECOMMENDED FLUIDS AND LUBRICANTSº).
2)After refilling coolant, run engine to ensure that no water-flow noise is emitted.
