SYMPTOM/CONDITION
Poor engine performance or no start during cold weather operation due to timing belt tooth skipping.
DIAGNOSIS
Timing belt tooth skipping on the subject vehicles may be caused by snow and/or ice being ingested into the timing belt area. This condition is rare, but
may happen when operating in very deep snow or during blizzard conditions.
The condition may not become apparent until the vehicle has been sitting in ambient temperatures below freezing for several hours, allowing melted
snow or ice to refreeze in the timing belt area. When the vehicle is then started, the ice can cause the belt to skip one or more teeth.
PARTS REQUIRED
1 - Sealing Package
PN 4419641
REPAIR PROCEDURE
It will be necessary to install a timing belt sealing package to prevent reoccurrence of this condition.
1.
Check camshaft timing as follows:
Engine Will Not Start
A.
Remove access plug from timing belt cover. Turn engine to #1 cylinder top dead center (use timing marks for reference).
B.
Looking through the access hole in the timing cover, check the location of the timing hole (if visible) in the camshaft sprocket. If the hole is
centered with the access hole in the cover the camshaft is timed properly.
NOTE:
THE HOLE WILL NOT BE VISIBLE IF THE CAMSHAFT SPROCKET IS MORE THAN TWO NOTCHES OUT OF
TIME.
C.
If the camshaft timing is wrong, retime as per service manual procedures.
D.
If the engine will not start, the belt could have skipped on the intermediate shaft, causing incorrect ignition timing.
E.
Verify this condition by turning the engine to #1 cylinder T.D.C. Remove the distributor cap and check the position of the rotor. If rotor is
out of the #1 cylinder firing position, it will be necessary to correct the intermediate shaft timing. Refer to the service manual for
intermediate shaft timing procedures.
2.
When camshaft and intermediate shaft timing has been verified, install the parts in kit, PN 4419641, as follows:
