ON-VEHICLE SERVICE
FRONT EXHAUST PIPE
Rattles and noise vibrations in the exhaust system are
usually caused by misalignment of parts. When aligning
the system, leave all bolts or nuts loose until all parts
are properly aligned; then tighten, working from front to
rear.
1. Check connections for looseness or damage,
especially for exhaust gas leakage.
2. Check clamps and rubbers for weakness, cracks or
damage.3. If any part of the converter heat shield is damaged
or dented to the extent that it contacts the catalyst,
repair or replace.
4. Check for dents or damage and for any holes or
cracks caused by corrosion.

ENGINE LUBRICATION 6G – 3
To meet a newly adopted electronically controlled fuel
injection system using engine oil two oil pumps have
been provided to increase circulating oil capacity.
The first oil pump serves mainly to lubricate the engine
parts, while the second mainly serves the fuel injectors
and partially cools the pistons.
The oil cooler is provided on the first oil pump side and
uses engine coolant.
