3. With the engine cool, check the overflow bottle level.

The fluid needs to be up to the bump on the outside
of the overflow bottle (Figure 62).

4. If the coolant level is low, add a 50/50 mix of

extended life antifreeze/Dex-Cool® and water to
the overflow bottle (Figure 62).

5. Add the 50/50 coolant mix to the overflow

bottle and fill it to the indicator line on the bottle
