Low coolant light stays on and coolant level is not low


Many times vehicles have a coolant sensor mounted on the radiator that goes bad allowing the low coolant light to stay lit changing this sensor usually takes care of the light also make sure the wires running to the sensor are not shorted or broke.

Why my low coolant light comes on at time. but its not low on coolant. i just put a new water pump on.


CHECK COOLANT OVER FLOW RESERVOIR MAKE SURE IT HAS COOLANT IF YES.YOU COULD HAVE A FAULTY COOLANT LEVEL SENSOR IN THE COOLANT OVERFLOW RESERVOIR. CHECK TO MAKE SURE ELECTRICAL CONNECTOR STILL INTACT.LIGHTLY TAP WITH THE HEAD OF A SCREW DRIVER BELOW COOLANT LOW LEVEL SENSOR BOTTOM OF COOLANT RESERVOIR.IF LOW COOLANT LIGHT GOES OUT COOLANT SENSOR PROBABLY STUCK IF LIGHT STAYS ON COOLANT LOW LEVEL SENSOR BAD.

Low coolant light came on 1999 Oldsmobile Silhouette, went out a couple minutes later without adding any coolant. Adding a little anyway after light went out. Now about 1 1/2 weeks later light came on...


If its not low on coolant and the light continues to come on it is the low coolant sensor in the radiator. This sensor is in the plastic side of the radiator and just pops off. These sensors are always a problem and don't always require replacement of the sensor. What happens -especially if you are using red DEX-COOL coolant is that the coolant gets hard and crusty inside the sensor and wont allow the coolant to enter and make contact with the sensor. Simply take the sensor off and blow compressed air or water pressure in it to free it of debris. Easy fix-hope this helps!

Replaced water pump, alternator, radiator, crank sensor and no coolant leaks and car has antifreeze, but why is low coolant dashboard indicator light keep flashing on 97 saturn sl2


Inside the coolant reserve tank there is a sensor for coolant level.


Over time,this sensor can get stick.


Inspect the coolant reserve tank for crack or leak.

Locate the coolant level switch/sensor and soak it in clean warm water.

Make sure it's free to move up and down the float path.

Top off the coolant tank with coolant only.

Coolant level low light comes on and coolant level is not low in reserve tank or radiator.


There is a TSB for this problem. Here it is.


Bulletin No.: 04-06-02-007

Date: August 11, 2004

TECHNICAL

Subject:
Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination)

Models:
2000-2002 Buick Century, Regal
2000-2001 Chevrolet Lumina
2000-2002 Chevrolet Impala, Monte Carlo
2000-2002 Pontiac Grand Prix
2000-2002 Oldsmobile Intrigue


Condition

Some customers may comment that the low engine coolant level indicator is always illuminated.


Cause

The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator.


Correction

Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below.


Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of "aftermarket" over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin.

1. Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL(R) mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin.

2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section.

3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light:


^ Light is on - Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI.

^ Light is out - Proceed to Step 4.



4. With the key off, connect the coolant level sensor into the vehicle's wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds.


^ Light is on - Replace the low coolant sensor and re-check system operation.

^ Light is out - Proceed to Step 5.


5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Re-install the low coolant sensor into the vehicle and proceed to Step 6.

6. Flush the cooling system and install new DEX-COOL(R) mixture as outlined in the SI. Check the vehicle's warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination.

1990 Regal Coupe 3.1 engine. Low Coolant Light Stays Lit


This is a COMMON Problem that GM had with the Level Sensor Curciut, And they Never Correctly Addressed it. I Have on ocations Replaced the Sensor and that Corrected the Problem, BUT Other times the Light STAYS ON No matter What, I have tracked the Wires and all I Have Ever Found was the Plug Being FAULTY. So if A NEW Coolant LEVEL SENSOR Does NOT Turn off the Light, try Replacing the PLUG Itself.
