3. Reinsert the dipstick, then remove it again without
screwing it into the filler neck. Check the oil level shown
on the dipstick.

4. A properly tensioned V-belt (Figure 7) should deflect
approximately 0.4–0.6 inches (5–10 mm) when 5 to 10
pounds of force are applied centrally between the
pulleys.
