Coolant Level Sensor Contamination - Disable Sensor - Service Action S145
Issue:
On some 4.0L V8 S-TYPE vehicles within the above VIN range, coolant has entered the coolant level sensor causing it to fail and give false readings. It has been decided that the coolant level sensor should be disabled for those 4.0L V8 vehicles affected within the above VIN range. The coolant level sensor was intended as a indication to the driver in case the coolant level is too low, since these vehicles are not equipped with fail-safe cooling as are the 3.0L V6 vehicles.
To disable the coolant level sensor follow the workshop procedure provided in this bulletin.
Action:
Perform the following modification on all 2000-01 MY 4.0L S-TYPE vehicles within the above VIN range at the next possible service opportunity.
Note:
Make sure that Service Action S139, Reprogram PCM, is completed before carrying out this modification.
