Timing Chain - Installation (Cont'd) - Cylinder Head (SR20DET)

EM-92prose procedure

This page covers SR20DET cylinder head bolt tightening (turbo). Step 15 (exhaust manifold with turbocharger) is SR20DET only.

Installation (Cont'd)

1
(a) Tighten all bolts to 59 N·m (6.0 kg-m, 43 ft-lb).
2
(b) Tighten all bolts to 108 to 118 N·m (11.0 to 12.0 kg-m, 80 to 87 ft-lb).
3
(c) Loosen all bolts completely.
4
(d) Tighten all bolts to 36 to 42 N·m (3.7 to 4.3 kg-m, 27 to 31 ft-lb).
5
(e) Method A: Turn all bolts 90 to 95 degrees clockwise with Tool or suitable angle wrench. Method B: If angle wrench is not available, tighten all bolts to 108 to 127 N·m (11.0 to 12.9 kg-m, 80 to 93 ft-lb).

Step	Tightening torque N·m (kg-m, ft-lb)
a	59 (6.0, 43)
b	113 ± 5 (11.5 ± 0.5, 83.2 ± 3.6)
c	0 (0, 0)
d	39 ± 3 (4.0 ± 0.3, 28.9 ± 2.2)
e	90 +5 -0 degrees or 117.2 ± 9.3 (11.95 ± 0.95, 86.4 ± 6.9)
