Coolant tank full and light still flashing

Open the container of antifreeze. Using a separate EMPTY gallon-size container, pour out HALF of the contents into the empty container, making sure not to spill any. Now, FILL the newly filled container with tap water. Fill the rest of the antifreeze with water, also. Now, you are ready to add antifreeze to your vehicle! Simply locate the radiator cap, (Don't touch it if it's hot!!) and unscrew it. Pour the desired amount of your mixed antifreeze into the radiator. Remember not to do this without proper knowledge!

Is it full of coolant if yes level sensor bad if not fill rad and overflow bottle to proper level and retest

If the coolant tank is full and the light is still coming on the coolant level sensor float may have sunk giving a false reading of an empty coolant tank. This is only repairable by replacing the coolant tank.

In a closed circuit the expansion tank is supposed to fill up, then, as the engine cools it sucks coolant back from the expansion tank. Drive the car and let it find the correct level, probably too full if you filled the system and the expansion tank.

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.

under the dash passenger side is a drain pipefor the AC condensation and it sounds like this pipe is blocked ,clean it out and this will cure the problem

most cars and trucks have a censor on radiator or fill tank,ck the coolant level and if it is full then censor should turn lights off if it is low fill with water to full line and light should turn off

Hello: That light means either the cooling system is low on coolant and/or a failed coolant sensor. Check the surge tank under the hood if it is empty, fill it to the level indicated. If low it could mean the cooling system has a leak. If tank is full then possibly you have a failed sensor.

There should be a fill level mark and yes you need to put in immediately, run the car until it reaches operating temp, then see where the level is after you shut it off.

i would replace the sensor located in over flow/fill tank its a common problem
