^ OIL DIPSTICK, OIL TUBE ASSEMBLY - NEW- 2.3L OHC - CURRENT OIL FILL


LIGHT TRUCK: 1985-87 RANGER
1986-87 AEROSTAR


ISSUE: Oil consumption (on vehicles with cast aluminum oil pans only) resulting from high engine oil levels may be caused by the "MAX FILL" mark on the oil dipstick being read incorrectly. Overfilling may cause oil to be drawn into the air intake system.

ACTION: To correct this, install oil level tube assembly (E6TZ-6754-F) and/or oil dipstick (E7TZ-6750-G) using one of the following service procedures.

NOTE: Two oil level tube assembly mounting locations have been used since 1985.

Oil Level Tube Assembly

1. If vehicle uses the side of intake manifold as a mounting surface for the old oil level tube assembly, then disconnect the old tube assembly and install the new tube assembly (E6TZ-6754-F) using same mounting hole and bolt.

If the old oil level tube assembly is mounted on bottom of intake manifold, remove the oil tube assembly and install the new oil level tube assembly (E6TZ-6754-F) to the side of intake manifold using a new (N605812-S2) bolt, see Figure 17.

NOTE: Mounting bracket hole must be enlarged to fit larger diameter (N605812-S2) bolt. This bolt has a torque-retention thread.

CAUTION: NEW oil level tube assembly must be fully engaged into the block for oil dipstick to indicate proper engine oil level. It must be bottomed out and sealed as shown in Figure 17.


2. Insert new oil dipstick (E7TZ-6750-G).

3. Drain oil from engine and replace oil filter.

4. Add five (5) quarts of oil to engine. Run engine five (5) minutes, shut off engine, and let stand five (5) minutes. Check engine oil level reading using new oil dipstick.
