4A–FE engine is an in–line, 4–cylinder, 1.6 liter DOHC 16–valve engine. Manual — part 7
HINT (When re–using timing belt): After loosening the
crankshaft pulley bolt, check that the timing belt match-
mark aligns with the end of the No.1 timing belt cover
when the crankshaft pulley groove is aligned with the
timing mark ”0” of the No.1 timing belt cover. If the
matchmark does not align, align as follows:
(When matchmark is out of alignment counterclockwise)
•
Align the matchmark by pulling the timing belt up
on the No.1 idler pulley side while turning the
crankshaft pulley clockwise.
•
After aligning the matchmark, hold the timing
belt. And turn the crankshaft pulley clockwise,
and align its groove with timing mark ”0” of the
No.1 timing belt cover.
(When matchmark is out of alignment clockwise)
•
Align the matchmark by pulling the timing belt up
on the water pump pulley side while turning the
crankshaft pulley counterclockwise.
•
After aligning the matchmark, hold the timing
belt. And turn the crankshaft pulley counterclock-
wise, and align its groove with timing mark ”0” of
the N o–1 timing belt cover.

INSPECTION OF TIMING BELT
COMPONENTS
1. INSPECT TIMING BELT
NOTICE:
•
Do not bend, twist or turn the timing belt inside out.
•
Do not allow the timing belt to come into contact
with oil, water or steam.
•
Do not utilize timing belt tension when installing or
removing the mounting bolt of the camshaft timing
pulley.
If there are any defects as shown in the illustrations,
check the following points:
(a) Premature parting
•
Check for proper installation.
•
Check the timing cover gasket for damage and
proper installation.
(d) If there is wear or damage on only one side of the
belt, check the belt guide and the alignment of each
pulley.
(c) If there is noticeable wear or cracks on the belt face,
check to see if there are nicks on the side of the idler
pulley lock.
(b) If the belt teeth are cracked or damaged, check to
see if either the camshaft or water pump is locked.

3. INSPECT TIMING BELT TENSIONER
(a) Visually check tensioner for oil leakage.
HINT: If there is only a small trace of oil on the seal of
the push rod, the tensioner is all right.
If leakage is found, replace the tensioner.
(c) Measure the protrusion of the push rod from the
housing end.
Protrusion: 8.5 – 9.5 mm (0.335 – 0.374 in.)
If the protrusion is not as specified, replace the tensioner.
(e) If there is noticeable wear on the belt teeth, check
the timing cover for damage, correct gasket installa-
tion and the foreign material on the pulley teeth.
If necessary, replace the timing belt.
(b) Hold the tensioner with both hands, and push the
push rod strongly against the floor or wall to check
that it doesn’t move.
If the push rod moves, replace the tensioner.
2. INSPECT IDLER PULLEYS
Check that the idler pulley turns smoothly.
If necessary, replace the idler pulley.
