here you go.
Tightening sequence of bolts:-
.................exhaust side...................
.....................3 1 6..........................
front of engine......... Rear of engine ....
.....................5 2 4..........................
..................inlet side........................
Then tighten torque and angle in the following stages, in the sequence above
1. 29 N/M OR 22 FT/LB
2. 69 N/M OR 51 FT/LB
3. BACK OFF 180 DEG. (REVERSE SEQ 6-1)
4. BACK OFF FURTHER 180 DEG (REVERSE SQ. 6-1
5. RE TORQUE 29 N/M OR 22 FT/LB (1-6)
6. 80 TO 90 DEG. (NOT OVER 90)
7. 40 TO 45 DEG. (NOT OVER 45)
8. NO.1 AND NO.2 40 TO 50 DEG. FURTHER (NOT OVER 50)
Step 1-2 are basically for settling the gasket, as step 3-4 pretty much take all the torque off. Put a little bit of oil (or better still a small blob of moly grease) on each bolt thread.
Don’t guess the angles. Get an angle disc for your torque wrench.
