"CAUTION: New cylinder head bolts must be used". Jeg trodde boltene kunne brukes 3 ganger... ?
7) Then, tighten the 14mm bolts with special tool
VM.1019 in the following manner: (Bilde)
( 8 ) 1st Phase: Tightening Head Bolts (Fig. 67).
Central bolts (A-L): Tighten all bolts, starting with
bolt I then J-K-L-A-B-C-D-E-F-G-H, to 30 N·m.
Tighten all bolts an additional 70°, starting with bolt
A and continuing in alphabetical order. Finally,
tighten all bolts an additional 70°, starting again
with bolt A and continuing in alphabetical order.
(9) Tighten the 12mm bolts in the following manner:
(10) Side bolts (M1-M2): Tighten M1 bolts to 30
N·m, then rotate them 85° (65). Tighten M2 bolts to
30 N·m, then rotate them 85° (65).
NOTE: If vehicle is equipped with A/C do not install
A/C lines to compressor and charge A/C till Phase 2
is complete.
(11) 2nd Phase: After 20 minutes of engine operation
at operating temperature, allow engine to cool
down completely. Then retorque the head bolts as follows:
(12) Central bolts A-L: Completely back off bolts
one-by-one and then retighten to 30 N·m plus 130°
(65°). Then proceed in the same way, bolt by bolt,
following alphabetical order, as indicated.
(13) Side bolts M1-M2: Without slackening,
torque bolts M1 then bolts M2 to 90 N·m (66 ft. lbs.).
(14) Torque intake nuts to 28 N·m (20 ft. lbs.) and
exhaust manifolds nuts to 32 N·m (24 ft. lbs.) after
completing the cylinder head torquing procedure.
"NOTE: The one piece steel type head gasket does
not require retorqueing." (etter 25.000 km var det vel ?)
