Engine Oil Filling
1. Add engine oil; use a funnel or pour spout to direct the oil into the opening (Figure 27 or Figure 28). With
filter change, the engine requires 1 qt. and 25 oz (1.7 L) of oil per change for gasoline vehicles and 3 qt.
(2.8 L) for diesel vehicles. Refer to oil viscosity guidelines for selection of oil grade (Figure 29 or
Figure 30). See following CAUTION.
CAUT ION
• Do not exceed recommended oil capacity. Doing so will decrease engine performance or
result in damage to the engine.
2. Connect the battery cables, positive (+) cable first, and tighten terminals to 12 ft-lb (16 N·m). Coat ter-
minals with Battery Terminal Protector Spray (P/N 603 00 00-03).
3. With the Forward/Reverse handle in the NEUTRAL position, start and run the engine for a few minutes.
Observe both the drain plug and the oil filter from under the vehicle and watch for oil leaks. If a leak is
detected, check the tightness of the oil filter and drain plug. Tighten, repair, and/or replace components
as necessary. See following NOTE.
NOTE: Wait five minutes after turning off the engine before removing the dipstick.
