Dodge Omni/Horizon/Rampage 1978-1989 Repair Guide

Fluid Pan



RTV silicone sealer is used in place of a pan gasket.

Chrysler recommends no fluid or filter changes during the normal service life of the car. Severe usage requires a fluid and filter change every 15,000 miles (24,000 km). Severe usage is defined as:

More than 50% heavy city traffic during 90°F (32°C) or warmer weather
Police, taxi or commercial operation or trailer towing

When changing the fluid, only Dexron®II or it's superceding fluid should be used at every fluid change.

  1. Raise the vehicle and support it on jackstands.
  3. Place a large container under the pan, loosen the pan bolts and tap at one corner to break it loose. Drain the fluid.
  5. When the fluid is drained remove the pan bolts.
  7. Remove the retaining screws and replace the filter. Tighten the screws to 35 inch lbs. (4 Nm).
  9. Clean the fluid pan, peel off the old RTV silicone sealer and install the pan, using a 0.12 in. (3mm) bead of new RTV sealer. Always run the sealer bead inside the bolt holes. Tighten the pan bolts to 10-12 ft. lbs. (14-16 Nm).
  11. Pour the specified amount of Dexron®II or it's superceding fluid through the filler tube.
  13. Turn the engine ON and idle it for at least 2 minutes. Set the parking brake and move the selector through each position, ending in Park.
  15. Add sufficient fluid to bring the level to the FULL mark on the dipstick. The level should be checked in Park, with the engine idling at normal operating temperature.
