when u have low coolant
Either the coolant reservoir is low on coolant or the coolant level sensor is NG.
Most vehicles have a coolant reservoir (a clear plastic tub) with a phrase "engine coolant only" printed on the cap. This is where you should add engine coolant.
The coolant expands when heated, contracts when cool. The coolant reservoir gives the coolant a place to come and go as needed.
Yes- coolant reservoir is designed to accept excess coolant - As coolant heats up it will expand and flow to the coolant recovery tank (reservoir) and as it cools (contracts) it will be sucked back into the radiator
when the engine is running and coolant will become hot to its operating temperature,the cooling system is under pressure,coolant will overflow and goes to coolant reservoir.when the engine goes cold coolant will go back to the rediator.
The coolant expands and rises when it is hot so it goes up, the coolant comes down when the car is cold.
You can use universal coolant which you can find in any auto parts store, or you can use a coolant for Japanese card, or you can go and get coolant at a local Toyota dealer.
Fill the reservoir with G12 VW coolant only and it will go into the engine.
Chances are it wont read the coolant levels meaning your car will go bang!
Engine coolant in an Alero is used in the radiator. A diagram and instructions for how to properly use the coolant can be found on the package instructions. An owner manual will also assist in proper use of coolant.
The coolant light is supposed to indicate when the coolant level is low. If you're certain that the vehicle coolant level is up, check the electrical connections and finally the sensor.
