LOOK FOR LEAKAGE,
REMEDY AS NECESSARY
- Start the engine.
- Look for leakage of oil, coolant, fuel, air and exhaust.
- Tighten or change leaking connections. Check the overflow holes (1)
which show whether the O-rings between the cylinder liner and crank-
case are leaking, see drawing.
a) If coolant is leaking out, the two upper O-rings are leaking.
b) If oil is leaking out, the lower O-ring is leaking.
- Check that the drain hole (2) on the coolant pump is not blocked, see
drawing. If there is leakage, change the pump seal.
A small amount of leakage from the overflow holes when running in the
engine is normal. (Seals and O-rings are fitted lubricated with soap or
oil).
This leakage normally stops after a time.
If there is a large amount of leakage - contact your nearest Scania
workshop.
