Driverside (left side) Exhaust Manifold Removal
Demonstration purposes only:
Parts needed: 17105-50121 – Exhaust Manifold Left; 17173-50021- Manifold gasket left; 90080-17187 nut (needs 8); 90080-12007 – Stud (needs 3 manifold to catalytic converter); 90080-12008 stud (needs 8 head to manifold).
Place front wheel straight.
Remove front left tire (secure front end with at least 2 jack stands: SAFETY is PRIORITY)
Remove engine bay splash shields (both small and big shields), engine and transmission skid plates
Loosen and remove three 14 mm manifold to cat flange nuts (use 6 sided box socket)
Loosen and remove two nuts and bolts (14 mm) located at the end of CAT, pre and post O2 sensors (12 mm)
Remove the catalytic converter
Loosen and remove TWO 12 mm bolts on steering shaft located at the top: right below the brake master pump (no need to remove the shaft at the bottom U-joint): Push the shaft adapter coupling up and no need to index the coupling as the coupling ONLY goes into the splines in one way.
Loosen and remove four 10 mm heat shield bolts
Remove the 12 mm bolt holding the engine oil dip stick tube (no need to remove the tube out of the engine)
Loosen and remove eight 14 mm nuts on manifold: HINT: use swivel box adapter (see images): Push heat shield down to access top nuts and push heat shield up to access four bottom nuts: NOTE: Use six sided impact grade 14 mm box socket and make sure the box socket is FULLY on the bolt- Avoid rounding the nut!
All 8 studs stayed on the head in my case.
I DID NOT LIFT THE ENGINE as suggested by other threads.
Turn the manifold to have four ports to face the hood (Manifold-CAT flange now faces transmission): Pull the manifold out
Clean the surface of the head
Installation
While keeping WHITE paint mark on the exhaust gasket on top right towards the firewall and shiny surface of the gasket towards the head, install the gasket.
Manifold and heat shield (don’t attach) must be place together into the engine bay.
While moving the heat shield up or down, attach all 8 nuts to studs by HAND.
Tighten the manifold nuts uniformly (like tightening the head gasket bots), finally, tighten the manifold nuts to 32 foot-pounds
Mount the dip stick bolt
Slide the steering shaft coupler back on to the bottom shaft (NOTE: there is only one way it will go on to the bottom shaft). Tighten two 12 mm bolts on the coupler
Swivel joint
Steering coupler where two 12 mm bolts located: must take bolts out to slide it up (I took this picture after removing the exhaust, but I had coupler removed at the very beginning)
Rotated picture: steering shaft to a side
