CHECKING THE ENGINE
COOLANT LEVEL
62R004
" 1 Reservoir cap
2 Upper 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. For information on
ethylene–glycol coolant, see also "Engine coolant selection"
described below.
If the coolant level drops within a short time after replenishing, there
may be a leak in the system. Visually check the radiator, hoses,
radiator cap, drain cock and water pump.
