(American Petroleum Institute) designation such as SH.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W±30. ªEnergy±Conserving IIº,
shown in the lower portion, indicates that the oil has
fuel±saving capabilities. Oils marked ªEnergy±Conserving

CHECKING THE ENGINE
COOLANT LEVEL

Reservoir capUpper lineLower line
Park the vehicle at a level spot and look at the
see±through coolant reservoir when the engine is cool.
The coolant level is satisfactory if it is between the
upper and lower lines on the tank. If the level is low, add
ethylene±glycol type coolant.
The coolant level in the reservoir will vary with engine coolant
temperature. However, if the level is on or below the lower
line, add coolant to bring the level up to the upper line.
Use only ethylene±glycol type coolant. It will prevent
freezing and corrosion. Neither supplemental inhibitors nor
additives are needed nor recommended. (For information on
ethylene±glycol coolant, see also ªEngine coolant selectionº
described below.)
