When someone say's "Check the coolant level" they simply mean to open the hood and look at that little white bottle on the passenger side fender to make sure that the bottle is full of coolant/water mixture. It has a line on it that say's "Full When Hot". If the light on the dash stays on and the bottle is full, shake the bottle, the float inside the bottle is stuck.
because your coolant level is too low. put some antifreeze in it......
it takes dex-cool coolant,
It is in the bottom of the over flow tank.
no cap, just the coolant tank, add to this to add coolant../
It is at the bottom front of the coolant reservoir.
check coolant sensor float most common problem.
If you are checking the coolant level at the overflow bottle, it may look normal (between the low & high marks). But the coolant level sensor is mounted on the passenger side of the radiator, down several inches from the top. In other words, you need to check the coolant level AT the radiator cap, but only when the engine is COLD. If it is OK at that point and the overflow bottle, then the coolant level sensor most likely needs to be replaced.
The coolant level sensor is bad
To bleed air out of the coolant system in a 2000 Chevy Tracker, first ensure the engine is cool and remove the radiator cap. Start the engine and let it run until it reaches normal operating temperature, allowing the thermostat to open. As the engine runs, keep an eye on the coolant level in the radiator; add coolant if necessary. Finally, rev the engine slightly and check for any remaining air bubbles; repeat this process until the coolant level stabilizes and no more bubbles are visible.
underneath the coolant tank, it should be easy to see.
dex-cool coolant is used in most 3.1 engines,
Low coolant level.
