1. Remove the connecting rod caps, then install the
ring compressor, and check that the bearing is
securely in place.
2. Position the arrow and the mark facing the timing
belt side ot the engine.
The mark must facethe timing belt sideof the engine.

Position the piston in the cylinder, and tap it in
using the wooden handle of a hammer.
NOTE: Maintain downward force on the ring com-pressor to prevent rings from expanding before
entering the cylinder bore.
Position all pistons at top dead center.

Oil Seal
Installation
The seal surface on the block should be dry.
Apply a light coat of oil to the crankshaft and
the lip of the seal.
1. Drive in tlywheel end seal against right side cover.
NOTE: Drive the end seal in squarely.

The seal surface on the block should be dry.
Apply a light coat of grease to the crankshaft and

pump.
When the seal is in place, clean any excess grease

Inspection
Remove the timing belt (81881 engine: see page 6-10, B'l8Cl,818C5 engines: see page 6-48).
Tu.n the water pump pulley counterclockwise.Check that it turn freely.
Check for sign6 of seal leakage.
NOTE: A small amount of "weeping" trom thebleed hole is normal.
BLEED HOLE
Remove the timing belt (81881 engine: see page 6-
10,818C1, Bl8C5 engines: see page 6-48).
Remove the camshaft pulleys and the back cover(B'1881 engine: see page 6-20, 818C1, 818C5

Feedback
Loop Status
Loop status is indicated as "open" or "closed".
Closed: Based on the H02S output, the ECM deter-
mines the airlfuel ratio and controis the amount of
iniected fuel.
Open: lgnoring HO2S output, the ECM refers to sig-
nals from the TP, MAP, and ECT sensors to control
the amount of iniected fuel.
Al idle speed: closed

Short Term
Fuel Trim
The airlfuel ratio correclion coeificient lor correcting
the amount ol iniected fuel when HO2S feedback is in
the closed loop status. When the signal from the
HO2S is weak, short term fuel trim gets highef. and
the ECM increases the amount of injected fuel The
airlfuel ratio gradually gets richer, causing a higher
HO2S output.
Consequentlv, the short term fuel trim is lowered, and
the ECM reduces the amount of injected tuel. This
cycle keeps the airlfuel ratio close to the stoichiomeric
ratio when in closed loop status.

The IAT sensor converts intake air temperature into
