DAF 95XF xe engine manual

The terms “COLD ENGINE” and “WARM ENGINE” are defined as follows:

• COLD ENGINE:A cold engine is an engine which, having reached operating temperature, has been allowed to cool down for at least six hours.
• WARM ENGINE:A warm engine is an engine which, having reached operating temperature, has not been at a standstill for more than thirty minutes.
• Direction of rotation of the engine:The direction of rotation of the engine is clockwise, as seen from the timing gear end.
• First cylinder of the engine:The first cylinder of the engine is the cylinder at the timing gear end.
• Left-hand and right-hand side of the engine:The left-hand side of the engine is the side where the fuel pump is mounted. The right-hand side of the engine is the side where the air compressor is mounted.

Cylinder head attachment bolts
Cylinder head bolts must only be used once. So the cylinder head bolts should always be replaced. The new cylinder head bolts have a red/brown sealant on the thread.

The tightening torques stated in this section are different from the standard tightening torques stated in the overview of the standard tightening torques. The other threaded connections which are not stated must therefore be tightened to the tightening torque stated in the overview of standard tightening torques. When attachment bolts and nuts are to be replaced, it is important that they are of exactly the same length and property class as the ones removed unless stated otherwise.

SAFETY INSTRUCTIONS
Do not run the engine in an enclosed or unventilated area. Make sure exhaust fumes are properly extracted. Maintain a safe distance from rotating and/or moving components. Various sorts of oil and other lubricants used on the vehicle may constitute a health hazard. This also applies to engine coolant, windscreen washer fluid, refrigerant in air-conditioning systems, battery acid and diesel fuel.
