PROCEDURE
INSTALL NO. 2 EXHAUST MANIFOLD HEAT INSULATOR
Install the No. 2 exhaust manifold heat insulator with the 3 bolts.
INSTALL EXHAUST MANIFOLD
Install a new exhaust manifold gasket to the cylinder head.
| *A | for Type A |
| *B | for Type B |
for Type A:
Install the exhaust manifold with the 5 nuts.
for Type B:
Install the exhaust manifold with new 5 nuts.
INSTALL MANIFOLD STAY
Temporarily install the manifold stay with the 3 bolts.
While pushing the manifold stay toward the exhaust manifold, tighten the 2 bolts labeled 1.
Tighten the bolt labeled 2.
INSTALL FRONT EXHAUST PIPE ASSEMBLY
Using a vernier caliper, measure the free length of the compression springs.
| Minimum length |
|---|
| 41.5 mm (1.63 in.) |
If the free length is less than the minimum, replace the compression spring.
Using a wire brush, remove any foreign matter from the gasket installation surface.
| *1 | Gasket |
| *2 | Wooden Block |
Using a plastic-faced hammer and wooden block, tap in a new gasket until its surface is flush with the exhaust manifold.
Note
Be sure to install the gasket so that it faces the correct direction.
Do not reuse the gasket.
Do not damage the gasket.
When connecting the front exhaust pipe assembly, do not push in the gasket with the front exhaust pipe assembly.
Install the front exhaust pipe assembly and 2 compression springs with the 2 bolts.
Install a new gasket to the front exhaust pipe assembly.
Connect the front exhaust pipe assembly to the center exhaust pipe assembly with the 2 bolts.
INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR
Install the No. 1 exhaust manifold heat insulator with the 3 bolts.
INSTALL WIRE HARNESS CLAMP BRACKET
Install the wire harness clamp bracket with the bolt.
INSTALL AIR FUEL RATIO SENSOR (for Bank 1 Sensor 1)
INSTALL NO. 2 CYLINDER HEAD COVER
