The light has no reset, when the signal from the sensor is working the light will go out, the problem is the low coolant sensor in the coolant recovery tank, it is cheap and easy to change.

    What is with the THANKS FOR TRYING??? I gave you the right answer, these little sensor are very sensitive to dirty coolant, is the coolant in the tank clean and free from sludge? I do this for free, I am a retired new car dealer technician of 30 years, just trying to help. Your rating is holey inappropriate.

Y dose the john dear 6330 run hot all the time even after it blowen out



Engine or hydraulic system overheating clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif Coolant system low on coolant in 6020, 6030, 6030 Premium, 7020, 7030 and
7030 Premium Series Tractors.

]clearpix.gif//-->
Symptoms
After several hours of work, warning system indicates hot engine coolant or hot hydraulic oil.
Situation or Problem
Coolant level in reservoir is between the "MIN" and "MAX" range but engine or hydraulic system is overheating.
Summary
Air is entering cooling system, hindering coolant flow. Check coolant level. Fill to the "MAX" line on the coolant reservoir.
Bleeding Cooling System:
The bleed valve (see Operator's Manual for location) on the radiator must be closed when the tractor is operating. Open the valve when coolant is drained or filled. If the bleed valve is left open, coolant will internally bypass between the low temperature circuit and engine high temperature circuit causing overheating. When bleeding the system, open the bleed valve and run the engine with no load for 5 minutes at 1700 rpm. Then shut engine off for 5 to 10 minutes before closing the drain valve. Check the coolant level. If level is below the "MAX" fill line, repeat this procedure until coolant level stays at the "MAX" line.

My low coolant light stays on on my 02 impala but the coolant is full how do I reset it?


The coolant level sensor is located on the passenger side of the radiator, just below the bottom of the battery. If the light comes on, you'll need to fill the plastic coolant tank. But you also need to remove the radiator cap and fill the radiator itself. Only open the radiator when the engine is cold. If the radiator is full, and you are positive it's full, then the sensor needs to be replaced.

I have a 95 grand am se 2.3 liter the other day my low coolant light came om i pulled over emediatley it was low i filled it and have been checking every time i go anywhere it is full and my low coolant...


You may have to reset it by putting in a code. You can find the code in your owners manual. In our Grand Am we have to reset the Check Oil light after we change the oil. For the oil light it is something like press the gas peddle in 5 times within 30 seconds....something like that. Good luck

How to reset low coolant sensor on 1999 buick century


Your cooling sensor is in the white plastic coolant tank that is on your firwall under the hood. If you fill it with coolant and the light continues to stay on. try and slap it a few times and see if that resets it. it could be gunked up. if that doesnt work fill the tank with radiator flush and let it sit for a little while and then flush the tank and refill with coolant.

I need sensors (master reset)


Open the DIS [Driver Information System] with the car running. The screen should flash all the annoying messages. Press the "Fuel" button repeatedly until the messages clear and it displays your fuel used. The press the Eng button until it shows your Oil Life, then hold down the reset button for 10 seconds. Then press Eng again till it shows your Transmission Fluid Life, and hold down the reset button for 10 seconds. As for the coolant indicator, make sure the reservoir is filled to the appropriate level. If you still get the Low Coolant message, check to make sure the coolant level sensor is plugged in (its on the reservoir) and if it is, then it may need replaced or cleaned.

I have a 1997 buick skylark and my low coolant light is on so i bought a gallon of the local advance autos 50 50 and filled the resevor let the car run 5 min with cap off level stayed the same am i doing...


Are you sure the coolant is still low in the bottle. The coolant sensor thats in the bottle has a float that can stick. If it sticks the low coolant light will stay on even if the coolant level is right. Try tapping on the coolant reservoir bottle in the area where the electrical wire enters it. Not too hard. If that is the porblem the light should reset.

Low Coolant light stays on


Check you coolant resevoir. The low coolant switch is located in the resevoir so if it is low on coolant there, the light will come on. If it is full, it could be that the switch is stuck due to gunk build up in the resevoir. Hope this helps you out
