Exhaust manifold

[Redneck]

Well the ice is finally gone and time to hit the lakes. Does anybody know the bolt torque specs for the exhaust manifold. I have a 2007 outback V the left manifold started leaking so I need to fix it. It does not make sense to take it to a dealer as I live to far away. I asked my dealer about it and he said "Just make them tight" and if you can believe it I was talking to the mechanic. I have searched the froums and the internet for the specs but no luck so any help would be great.

Thanks

I would give the guys at Discount Inboard Marine a shout.They will have an answer.

you must not be as "red" as you think ! LOL, thats good solid shade-tree advice. just use some good common sense on torqing sequence... not near as critical as some other parts... I'd keep rotating a good balanced tightning sequence, after all is bottomed out good go back over them one last time, run it for a day, then re-check'em. Just dont use a huge pull handle so as to over leverage and twist a bolt off ... YOU CAN DO IT!!! :-)

I assume you have the cast iron exhaust manifolds. Indmar does not use a gasket between the manifold and the head on those units. A bead of hi-temp silicone sealant around the exhaust ports is all that is needed. Tighten the bolts starting in the center and work your way out. First pass to 11 foot pounds and second pass to 22.

Every bolt has it's own torque setting based on its size and thread. Torque to Yield is slightly different, but there is a chart for those also.

Thanks for the input people. Engine nut gave the torgue spec I was looking for. Keep up the good work.

Time for the lake.

but if you ever need a target taken out, maxpower is your man!

If you know the bolt size you should be able to look up standard torque values for the size bolt. Hit the internet and do a search for bolt torque values. This will work fine as both the manifold or block are standard types of materials, ie not aluminum or any other soft material that would need special considerations.
