Question torque specification on the headers

OK, so anybody out there removed the headers on the F4 1000s?

Iím trying to remove them so that I can ceramic coating the exhaust system.

Not exactly an ace mechanic but not exactly incompetent when it comes to vehicles ether, taking the exhaust off shouldnít be a big deal. But Iíve been proven wrong on many occasions.

First off what is the torque specs on the 12mm bolts holding on the header plate.

Being that itís a tight space I canít seem to get it off with a small socket wrench, and I didnít really want to drain the radiator/ remove the radiator to get a larger socket wrench on the bolts. Removing the radiator just sounds like a pain in my ass. By the way I can also see that the bolts on the left side is starting to round off but at this point are still fine, Iím guessing that itís probable past its original torque specification when it was put on last or itís just set in place do to the heat.

Is there something that Iím missing ore some magic step to get the bolts out or do I just have to whale on them but that seems futile at this point?[



Any bright ideals?

wd40 is a good tip, just let it soak for 24 hrs

if that doesn't work, try letting the engine run a bit so the bolts get hot

good luck!

Yes, as above will work, the torque for nuts is 16-18 N-M. Thats for the 750, basically the same.
Goodluck.

I would use kroil instead of WD40 if I were you.

just be patient...i was able to get all 8 bolts on and off with just a regular wrench and small socket set. You just need to really snake it up around in out back forth etc to get a good angle on the inside bolts.

A wrench with a built in ratchet works but get the one with 6 point and not 12 and don`t even look too hard at those radiator finns or they will bend.

I think we might be talking about different models; there is only 1 bolt on a ďXĒ style plate on each of the 2 exhaust headers bolted on to the head. It's not a clamp style connection.


Anybody know what the torque spec is on that style?

WD-40 was a good idea, tried that last night but to no avail.

Iíll let you know how warm up the engine goes.
