SOURCE: the "check coolant level" message

Hello: You didn't post what year/model car. If its 1996 or newer the coolant level sensor is located in the overflow tank. Sometimes you can tap on the tank near the sensor and it will work. Make sure the sensor is connected, not easy to get access to it. To replace the sensor you will have to replace the tank.

Two cooling fans controlled by three relay's . If only one fan is working ,that could be a problem .
Coolant Level Sensor Description
The coolant level sensor monitors the coolant level in the cooling system and indicates if the coolant is low. This sensor is located at the base of the radiator surge tank and is not serviceable.
CHECK COOLANT LEVEL (2)
The IPC receives a discrete input from the engine coolant level switch. The engine coolant level switch is normally closed. When the engine coolant is low, the engine coolant level switch opens. When the IPC receives an open signal from the engine coolant level switch, the IPC displays the message on the DIC.

Cooling system


Raise the car front end as high as possible with a floor jack, fill the coolant tank to the top, run the engine until it reaches just short of overheating, shut it down and run water over the radiator, this will burp the air out. Repeat as needed. Don't let the coolant recovery tank run dry during procedure.

CODE #PO128 KEEPS RETURNING AND AC CUTTING IN & OUT


It's a thermostat/coolant issue. The definition is here:


P0128 Engine Coolant Temperature Below Thermostat Regulating Temperature



Possible Causes
  • Check the operation of the thermostat (it may be stuck open)
  • Coolant level is too low, or the coolant mixture is incorrect
  • ECT sensor connector is damaged (check pins for damage, and for moisture)
  • ECT sensor signal circuit has a high resistance condition
  • ECT sensor has failed

Heat doesn't work all the time


Check the coolant level. If it is low, the heat won't work at idle, only when accelerating. If it gets even lower, it will overheat.

This trouble is common in this models, I have one '93 ZJ and my signal Sensor Coolant Level also is ON for long time; first, try to clean the plug and reset the ECU. If the signal show again, maybe you need replace this sensor.

- Page 11 Diagnostics/Service Procedures
- Page 24 Removal Components
