Section 4
Hot Check Procedure
The fluid should be at the normal
operating temperature (82-93°C)
(180-200°F) when you check it.
The hot check procedure is the
most accurate method to check
the fluid level.
Check the fluid level at every
engine oil change:
1. Park the vehicle on a level sur-
face and apply the park brake.
2. With the shift lever in P (Park),
start the engine.
3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about 3 seconds in
each range. Then position the
shift lever in
P (Park).
4. Run the engine at idle speed
for about 3 to 5 minutes.
5. With the engine running at
idle speed, remove the dip-
stick, wipe it clean and reinsert
it by pushing it down all the
way.
6. Wait for 3 seconds, remove
the dipstick again and check
the fluid level.
Keep the dipstick pointed
down to get an accurate
reading.
Check both sides and read the
lower level.
