See the attached simplified image of the exhaust system from the shop manual. [I have added the conversion legend.] The torque recommendations do not make sense to me. The only one that seems correct is the "59-80 N-m (6.0-8.2 m-kg, 43-59 ft-lb). The other specs are supposedly in inch-pounds, but if you do the conversions, they are all incorrect. Especially disturbing is the torque for the bolts/nuts connecting the down pipe to the turbo. According to a conversion of 44-53.9 N-m, the torque in ft-lbs should be 33-40, or the inch-pound equivalent: 12 x 33=396 or 12 x 40=480.

What am I missing? I definetely do no want to over tighten any of those bolts/nuts. Comments appreciated!

 

In/lbs????

No, it is ft lbs.

 

But if you convert N-m to either in-lb or ft-lb, neither one agrees with the conversion shown in the graphic. Only the one I mentioned (the 3 main flanges) seems to be correct.

 

i dont really think its that big of a deal without being any experienced mechanic, just thighten so the screw aint loose ( abit more of course : )or the paint/metal/texture chips off from too much force...

 

Tighten the one in question to 45 ft lbs. Think it is just a typo, but almost all the exhaust 14mm nuts can be torqued to between 45 and 60 ft lbs with no issues.

 

Yeah, that would be more like it for sure. Thanks!

 

it's exhaust, your car will not blow up in the event you over/under tightened a bolt or two. tighten it until the two parts make contact and just tighten until you REALLY have to get on the wrench to go any further.
