It’s important to know the coolant level to prevent the engine from overheating and causing damage.

  1. Locate the reservoir under the hood of your car, which is located on the left front side.

  2. Notice where the coolant level is on the side of the reservoir. You should see a line with F for full and a line with L for low.


Do not open the coolant cap on a hot engine.

If the coolant is below the F line, have a mechanic check your car and add coolant. There may be a leak somewhere that requires repair.
