Helpful Tips for removing Stock Exhaust Manifold

[mlk_f1]

I was trying to post this in the library but was denied access. So, if you Mods find this worthy, please move this to the Library section.

This might be helpful for those that plan to install header.

1) You do not need to remove Belt Tensioner
2) Nor, have to hacksaw the Air Injection tube off.

Stock Exhaust Manifold removal tips without the need of hacksaw or belt tensioner removal.

1) remove Cat, Exhaust Manifold upper and lower heatshields.

2) remove the 2 nuts and 3 bolts holding the Exhaust manifold. Also remove the one nut holding the Air injection tube from the rear right wheel well.

3) Remove the stud circled in RED below with a Torx socket.


4) Slide the exhaust manifold out until you have access to the Air Injection Tube Cap from the Rear Right Wheel well.

5) Use a plier to slide the clip free from the rubber hose cap circled in red below. You need to do this from the Rear Right wheel well. Remove the Hose Cap and Clip completely.


6) Now you can slowly work the whole Exhaust Manifold out of the engine bay from below. Trust me, it will come out at just the correct angle. Be patient.

Good luck.

Good tip, this looks like the best solution for getting the old manifold off.

Is there a reason to keep the cold air injection pipe once it's out? I'm considering doing this, but am thinking about cutting the cold air injection pipe off near the header and plugging it so it doesn't have to be snaked back beside the engine.

Thanks for posting this--just tried it (well--I'm taking a break before i torque the nuts and bolts). I removed both of the studs and the rest was just as you said.

A couple of comments, though... I didn't go in through the passenger wheel well because I'm using rhino-ramps. The air tube fasteners were fairly easy to reach from the bottom.

But mostly, in step number 6, when you say 'patient', you should put that in bold, and underline it, and put it in caps, and underline it again!

But it all worked out. Thanks again.

FYI: Sears has a seven piece external Torx socket set on sale today and tomorrow for $19.95:

It was also in yesterday's flyer in the local newspaper...

Nope - its not hooked to anything anyways - the Elise doesn't have air injection. lately I've cut off and welded up all the ones I've ported.
