INSTALLATION
| CAUTION | Do not reuse gasket. Do not reuse seal bearing. Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor. Use a new one. Before installing a new heated oxygen sensor 2, clean exhaust system threads using a suitable tool and apply anti-seize lubricant. Oxygen sensor thread cleaner: J-43897-12 Oxygen sensor thread cleaner: J-43897-18 Do not over tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sensor 2, resulting in the "MIL" coming on. Prevent rust preventives from contacting sensor body. If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat insulator, remove them. When installing heat insulator avoid large gaps or interference between heat insulator and each exhaust pipe. Remove deposits from the sealing surface of each connection. Connect them securely to avoid exhaust gas leaks. When installing each mounting rubber, use silicon oil to avoid twisting. Temporarily tighten nuts and bolts. Check each part for unusual interference and mounting rubber interference, and then tighten them to the specified torque. When installing each mounting rubber, avoid twisting or unusual extension in up/down, front/rear and right/left directions. |

Scheme 5
Scheme 6
- Place a piece of wood (A) on seal bearing (2) and securely insert the seal bearing on the exhaust manifold (1) side, using a plastic hammer (B). CAUTION: Do not damage the seal bearing surface during insertion. If seal bearing is inserted by hammering directly without using a piece of wood, the seal bearing is deformed and exhaust gas leaks. To insert seal bearing, always use a piece of wood and insert straight.
- Check that seal bearing (1) is in absolute contact (C) with the flange (A). If there is clearance (B), insert seal bearing straight by hand to bring the seal bearing into absolute contact with the flange. CAUTION: Do not use a tool for insertion. Do not insert seal bearing by tightening exhaust front tube.
- With spring (3), tighten nut (4). CAUTION: Ensure springs are seated correctly on the flange and not sitting on locator dimple (A). Be careful that stud bolt does not interfere with mounting hole of exhaust front tube (<==).
- After installing, check that bolt does not interfere with mounting hole of exhaust front tube.
Scheme 7
- Securely insert seal bearing (2) into exhaust front tube (1). CAUTION: Be careful not to damage seal bearing surface when installing.
- With spring, tighten bolt. CAUTION: Ensure springs are seated correctly on the flange and not sitting on locator dimple (A). Be careful that bolt does not interfere with mounting hole of center muffler.
- After installing, check that bolt does not interfere with mounting hole of center muffler.
