The overflow resavour is where you add coolant
Make sure the car engine is cooled off, preferably early in the day before the car has been started. The coolant tank is on the passenger side under the hood. Fill the tank to the line that says "full..cool" and you're done.
Cold engine. Remove the radiator cap, top it off, start the engine, add coolant as necessary until all air bubbles stop escaping.
add antifreeze
Add coolant to the full cold line on the coolant reservoir when engine is cold.
Just pour it into the coolant tank. Don't overfill, use 50% water and get an extra 15lb coolant tank cap.
Remove the radiator cap when the engine is cool and add the coolant into the radiator or you can add to the coolant overflow bottle. DON'T remove the radiator cap when the engine is hot!!!
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.
All engine coolant is roughly the same but some are advertised for performance cars.
The coolant add/overfill jug is on the left side of the motor when your looking at it. Add coolant up the closest line towards the top, and only when the engine is cold.
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
coolant overflow tank. probably on top left side of engine towards the front.
yes, should never add coolant to cold engine
