3.10 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.

Steering gear and brake system

3.16 CHECKING THE UNIVERSAL JOINT ATTACHMENT ON STEERING BOX 

INPUT SHAFT

1.

Check the universal joint for perceptible play. 

If perceptible play is detected, the affected 

part must be replaced.

2.

Check whether there is any perceptible play 

between the spline connection of the 

universal joint and the steering box input 

shaft. If perceptible play is detected, the 

splines on the universal joint and those on 

the input shaft must be checked for wear. If 

wear is detected, the affected part must be 

replaced.

3.

If there is perceptible play but the parts are 

not worn, the attachment bolt and nut must 

be replaced. Tighten the attachment bolt and 

nut to the specified torque, see "Technical
