Caution
^ During engine repair procedures, cleanliness is extremely important. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages, coolant passages or the oil pan may cause engine failure.
1. Remove the bolts and the flexplate.
2. Remove the engine-to-transaxle separator plate.
3. Using the special tools, remove and discard the crankshaft rear oil seal.
4. Mount the engine on a suitable stand.
5. Detach the wiring harness connectors from the upper intake manifold.
6. Detach the wiring harness retainer, remove the nut and the catalyst monitor sensor electrical connector bracket.
7. Disconnect the crankshaft position (CKP) sensor electrical connector and detach the wiring harness retainers.
8. Disconnect the exhaust gas recirculation (EGR) vacuum regulator electrical connector.
9. Remove the 2 wiring harness retainer nuts.
10. Disconnect the idle air control (IAC) valve and the throttle position (TP) sensor electrical connector.
