Possible, but not likely. The check engine light is mainly for emission failures not fluid levels. Have it checked for codes to know the cause.
The coolant level is low.The coolant level is low.
If there is a cap on the radiator you can check to see if the radiator is full , and if it isn't , " top up " the engine coolant . Otherwise , you check the engine coolant level at the engine coolant reservoir when the engine is cold and maintain the level at the cold mark
Check the engine coolant... Is it full? yes coolant level is full
That means the engine is running HOT. Need to check the coolant level and check for coolant leaks.
It is possible that a check engine light on a Toyota Highlander will come on if the coolant level is low. Usually, though, there is another light that will come on that says 'low coolant' on some older Toyota's.
when the engine is cool, check the anti-freeze level. it may be low.
When a vehicle randomly overheats, it is likely that the coolant level is low. Check the and fill the level to proper amount.
The plastic coolant reservoir on the fender feeds directly into the coolant system. Just add coolant to the reservoir and if you have drained the coolant or otherwise emptied the system, you may need to check the level in the reservoir after running the engine, or more accurately, after the engine has cooled. Once the coolant level has stabilized, just check it periodically to make certain that the coolant level never gets too low.
If the coolant reservoir can not maintain the proper level of coolant, it is possible the engine could over heat when the level drops.
Check to coolant level in the coolant recovery tank and radiator when engine is cold
check/replace the engine coolant level sensor located in the engine coolant overflow reservior (located at the rear of the engine compartment pass. side)
Check the coolant level. Usually low coolant levels will cause this.
