1. Check the coolant level in the reservoir when
the engine is cold as the coolant level will
vary with engine temperature. The coolant
level should be between the maximum and
minimum marks.
2. If the level is low, remove panel D. (See page
8-17 ~ 8-19 for panel removal and installation
procedures.)
