Do not fill with engine oil above the ºFº mark.

Install the oil dipstick facing the direction shown in
the illustration.

2,
43 - 85 psi)
8. REMOVE OIL PRESSURE GAUGE
9. REINSTALL OIL PRESSURE SWITCH
(a) Apply adhesive to 2 or 3 threads of the oil pressure switch.

(b) Differential:
Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole. If the level is low, add oil
until it begins to run out of the filler hole.

Resistance: 0.2 - 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump and/
or the lead wire.
(g) Inspect the fuel pump operation.
Connect the battery positive (+) lead to terminal 4 of the
connector, and the battery negative (-) lead to terminal 5.
Check that the fuel pump operates.
NOTICE:

These tests must be done quickly (within 10 seconds)
to prevent the coil burning out.

Keep the fuel pump as far away from the battery as
possible.

Always change the connection on the battery side.
If operation is not as specified, replace the fuel pump and/or
lead wire.
(h) Reconnect the fuel pump & sender gauge connector.
(i) Reinstall the rear floor service hole cover with the 2
screws.
