PROCEDURE
INSTALL NO. 1 MANIFOLD CONVERTER INSULATOR
Install the No. 1 manifold converter insulator onto the exhaust manifold converter sub-assembly with the 2 bolts.
INSTALL EXHAUST MANIFOLD CONVERTER SUB-ASSEMBLY
Install the new exhaust manifold to head gasket and inlet EGR gasket onto the cylinder head sub-assembly.
Temporarily install the exhaust manifold converter sub-assembly onto the cylinder head sub-assembly with the 2 bolts and 4 nuts.
Tighten the 2 bolts and 4 nuts in the order shown in the illustration.
INSTALL MANIFOLD STAY
Temporarily install the manifold stay with the 2 bolts.
Tighten the 2 bolts in the order shown in the illustration.
INSTALL EGR INLET EXHAUST MANIFOLD PLATE
Install the EGR inlet exhaust manifold plate onto the No. 1 water by-pass pipe with the 2 bolts.
INSTALL HEATED OXYGEN SENSOR
INSTALL FRONT EXHAUST PIPE ASSEMBLY
Using a vernier caliper, measure the free length of the compression spring.
| Minimum Length |
|---|
| 41.5 mm (1.634 in.) |
Tech Tips
If the length is not as specified, replace the compression spring.
| *1 | Exhaust Pipe Gasket |
| *2 | Wooden Block |
Using a plastic hammer and a wooden block, tap in a new exhaust pipe gasket until its surface is flush with the exhaust manifold converter sub-assembly.
Note
Install the gasket in the correct direction.
Do not reuse the gasket.
Do not damage the gasket by dropping it, etc.
Do not damage the outer surface of the gasket.
Do not push in the gasket with the exhaust pipe when connecting it.
| *1 | Exhaust Manifold Converter Sub-assembly |
| *2 | Front Exhaust Pipe Assembly |
| *3 | Exhaust Pipe Gasket |
| *a | Space between flanges: 8.5 mm (0.335 in.) |
Install the front exhaust pipe assembly to the exhaust manifold converter sub-assembly with the 2 compression springs and 2 bolts.
Note
After the installation, check that the gaps between the flanges of the exhaust manifold and front exhaust pipe assembly are consistent front-to-rear and left-to-right.
Engage the 3 clamps and connect the No. 2 heated oxygen sensor wire to the fan shroud.
Connect the connector of the No. 2 heated oxygen sensor.
