Coolant level
Checking
1. Let the engine cool.
2. Turn the cap of the expansion tank slightly
counterclockwise to allow any excess pressure
to dissipate, and then open it.
3. The coolant level is correct if it lies between the minimum and maximum marks in the filler neck.
4. If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5. Turn the cap until there is an audible click.
6. Have the cause of the coolant loss eliminated
as soon as possible.
