Torque Sequence

[nolafishr]

I need the Torque Sequence for a Exhaust Manifold, I will be changing the Stock one out on My 06 and need this to Tighten the new one.

If you can't get the specific sequence, you can always just pull them all up snug, then starting in the middle, work your way in a circular pattern from the middle to the outside. Usually, this is the factory sequence anyway... Just make sure that you get them all pulled up snug first.

Wingate's got the answer...

When we installed a new ATS manifold they sent us a torque sequence with the manifold... it started in the center of the manifold and worked clockwise and out... one bolt at a time... 25 ft lbs, 45 ft lbs and I think the final setting was 75 ft lbs...

But consult your installations instructions as I'm doing this from memory... .

One point of interest... before we replaced it... we asked if the 2 piece manifold would seal with an exhaust brake. . now 3K miles later its still not 100% sealed and we have trouble pulling a very heavy trailer... but I've just not got back in touch with them...

Their sales guy said it would work fine with an exhaust brake... .

1. Using new exhaust manifold gaskets, install the exhaust manifold. Install the bolts and spacers and tighten the

bolts in the sequence shown in to 43 N•m (32 ft. lbs. ) torque.

2. Retorque the four center bolts.

3. Install heat shield and torque nuts to 24 Nm (18 ft. lbs. ).

4. Install cab heater tube.

5. Install exhaust manifold bolt retention straps.

6. Install the cab heater return tube brace to the manifold bolt stud. Tighten the nut to 24 N•m (18 ft. lbs. ) torque.

7. Install the turbocharger and a new gasket. Tighten the turbocharger mounting nuts to 43 N•m (32 ft. lbs. ) torque.

8. Raise vehicle on hoist.

9. Install the oil drain tube and a new gasket to the turbocharger. Tighten the drain tube bolts to 24 N•m (18 ft. lbs. )

torque.

NOTE: A new exhaust pipe to turbocharger elbow must be used. Do not reuse clamp.

10. Connect the exhaust pipe to the turbocharger and tighten the bolts to 11 N•m (100 ft. lbs. ) torque.

11. Connect the wastegate command valve connector.

12. Lower the vehicle.

13. Pre-lube the turbocharger. Pour 50 to 60 cc (2 to 3 oz. ) clean engine oil in the oil supply line fitting on the

turbo. Rotate the turbocharger impeller by hand to distrubute the oil thoroughly.

14. Install and tighten the oil supply line fitting nut to 24 N•m (18 ft. lbs. ) torque.

15. Position the charge air cooler inlet pipe to the turbocharger. With the clamp in position, tighten the clamp nut to

11 N•m (95 in. lbs. ) torque.

16. Position the air inlet hose to the turbocharger. Tighten the clamp to 4 N•m (35 in. lbs. ) torque.

17. Connect the battery negative cables.

18. Start the engine to check for leaks.

One point of interest... before we replaced it... we asked if the 2 piece manifold would seal with an exhaust brake. . now 3K miles later its still not 100% sealed and we have trouble pulling a very heavy trailer... but I've just not got back in touch with them...

Well... That makes the 1 piece stainless ones look good now doesn't it!
