3.

Check/correct the valve clearance of the

specified inlet and exhaust valves. Set the

correct valve clearance by loosening the

locknut and rotating the adjusting screw in

the correct direction; see "Technical data" for

the correct valve clearance.

4.

Using an open-end spanner on the fan shaft,

turn the crankshaft one rotation further so

that the mark (A) is once again between the

bolts (B) and the valves of cylinder 6 overlap.

5.

Check/correct the valve clearance of the

specified inlet and exhaust valves. Set the

correct valve clearance by loosening the

locknut and rotating the adjusting screw in

the correct direction; see "Technical data" for

the correct valve clearance.

6.

Fit the valve cover. See "Removal and

installation".

3.11 CHECKING THE POLY-V-BELT

1.

Check the poly-V-belt for damage and signs

of serious wear.

3.12 CHECKING THE COOLANT FREEZING POINT

When the coolant is hot, there is an

overpressure in the cooling system.

Carefully remove the filler cap to

release the overpressure.

Do not remove the filler cap when the

engine is running.

Coolant is a toxic fluid. Contact with

the skin should therefore be

avoided.

In the event of contact with the skin:

remove with paper or a cloth, wash

with soap and water. If irritation

persists, consult a doctor.

If swallowed: DO NOT induce

vomiting. Rinse mouth, drink two

glasses of water and consult a

doctor.

In the event of inhalation: get some

fresh air and rest.

In order to avoid damaging the

cylinder block, do not top up a warm

engine with coolant.

1.

Check the anti-freeze content of the coolant.

Fill the cooling system with anti-freeze, if this

has not been done yet. Always use only

coolants that meet DAF specifications.

2.

Consult the manufacturer’s instructions for

the correct anti-freeze mixing ratio.

Preferably, use 40% anti-freeze on an

ethylene glycol base. At this percentage, not

only good frost protection, but also good

corrosion protection is guaranteed.
