DESCRIPTIONNLEC0623A water draining cock is on the lower side and a priming pump for
bleeding air is on the upper side.
SEF375Y
AIR BLEEDINGNLEC06241. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds. To start the engine more quickly, crank the engine
while pumping the priming pump (requires two workers).
3. If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
+When air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop the operation at that
time.
+If it is difficult to bleed air by the pumping of the priming
pump (the pumping of the priming pump does not become
heavy), disconnect the fuel supply hose between the fuel
filter and the injection pump. Then, perform the operation
described above, and make sure that fuel comes out. (Use
a pan, etc. so as not to spill fuel. Do not let fuel get on
engine and other parts.) After that, connect the hose, then
bleed air again.
+Start engine and let it idle for at least one minute after
performing air bleeding.
WATER DRAININGNLEC0625+If the MI lights up (not flashes) during the engine operation,
drain the water as follows. (If fuel filter switch is equipped.)
1. Remove the fuel filter, filter bracket, protector assembly from
the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and
vacuum hose for brake booster (between the vacuum pump
and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape,
etc. to prevent foreign object from getting into the engine
during the operation.
b. Disconnect the water level warning sensor harness connector.
c. Remove the mounting nuts on the dash panel, then remove the
fuel filter, filter bracket, and protector assembly from the dash
panel.
+It is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock
at the bottom of the water level warning sensor located under
the fuel filter.

NOTE:
If SRS does not enter Diagnosis mode even though malfunction is
detected in User mode, check the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then go
to DIAGNOSTIC PROCEDURE 7, page RS-60.
If the battery voltage is OK, replace the diagnosis sensor unit.
