The Duratec 1.8 and 2.0 are as follows:
Tighten the cylinder head bolts (in sequence) in five stages:
• Stage 1: 5 Nm.
• Stage 2: 15 Nm.
• Stage 3: 45 Nm.
• Stage 4: 90 degrees.
• Stage 5: 90 degrees.
The sequence starts from the centre pair of bolts and works outward and on opposite sides. That is to say Centre LH, Centre RH. 1 back from centre (left and right) then 1 forward from centre (left and right) until completed.
The earlier 1.6-2.0 Zetec engines are tightened using the same order but to these specs:
Stage 1: 20 Nm
Stage 2: 40 Nm
Stage 3: 90 degrees
Please note that in some Zetec applications the Stage 3 tightening is to 105 degrees
Cheers
Russ
