Oil Pan REMOVAL & INSTALLATION

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Drain the crankcase.
3. Remove or disconnect the following:
   • Negative battery cable
   • Oil level indicator harness connector, if equipped
   • Exhaust Y-pipe, if needed
   • Transaxle assembly from the vehicle.
   • Oil pan bolts and the oil pan
   To install: NOTE: The oil pan gasket is reusable unless it is damaged. Do not remove the gasket from the oil pan groove unless gasket replacement is required.
   
4. Thoroughly clean the inside of the oil pan and the cylinder block contact surface. If the oil pan gasket is being reused, be careful not to damage it. Do not expose the gasket to cleaning solvents.
5. If a new gasket is being installed, start the gasket into the oil pan groove and work the gasket into the groove in both directions. Once the gasket is exposed to oil, it will expand and no longer stay in the groove without wrinkles. If this condition exists, replace the gasket.
6. Install or connect the following:
   • Oil pan. Torque the bolts, in sequence, to 89 inch lbs. (10 Nm).
   • Oil level indicator connector, if removed
   • Transaxle assembly, if removed
   • Y-pipe, if removed
   • Flywheel cover, if removed
   • Oil pan drain plug. Torque it to 15 ft. lbs. (20 Nm).
   • Negative battery cable
7. Refill the crankcase.

No big job Really. Just locate your Drain Plug for the Oil. Thepan is right there, Remove the Bolts around the Pan and Remove. You will lose all of your oil so, Have something there to catch it all. Clean it all around the Edges of the Block where the Pan mounts with Degreaser and Make sure that you Scrape the Old Gasket off of Both the Block and the Pan. Run a Thin Bead of Blue ATV Silicone around the Pan Edge, Lay the Gasket on top of this Silicone. Put another Thin line on top of the Gasket and Reinstall. This Silicone is High Temp Silicone and will Seal Very Well. Make sure to put oil Back in the Motor! Please Rate my Response, I need all the Help That I can Get! Thanks!
