Cleaning
-
Clean the exhaust manifold using a suitable solvent. Use
a plastic scraping tool to clean the gasket sealing surfaces.
Inspection
-
NOTE:
New exhaust manifold gaskets, studs, nuts and/or
bolts must be installed when an exhaust manifold is serviced.
NOTE:
Use a Straightedge that is calibrated by the
manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of
length, such as Snap-On® GA438A or equivalent. For example, if the
Straightedge is 61 cm (24 in) long, the machined edge must be flat
within 0.010 mm (0.0004 in) from end to end.
Using the Straightedge and a Feeler Gauge Set, check the
exhaust manifold sealing surface for warpage. If the warpage is greater
than 0.76 mm (0.0299 in), install a new exhaust manifold.
Use the General Equipment: Feeler Gauge

Check
NOTE:
Refer to the appropriate Section 303-01 for the specification.
NOTE:
Make sure all cylinder head surfaces are clear of
any gasket material, silicone sealant, oil and coolant...

NOTE:
Do not clean the dual mass flywheel with any kind of fluid,
use a dry cloth only or damage to the dual mass flywheel may occur...

Inspection and Verification
Verify the customer concern.
Visually inspect for obvious signs of mechanical or electrical damage.
If an obvious cause for an observed or reported concern is
found, correct the cause (if possible) before proceeding to the next
step
If the cause is not visually evident, verify the symptom and refer to the Symptom Chart...
Categories
Preliminary Inspection
Verify the customer concern by carrying out a road test on a
smooth road. If any vibrations are apparent, Refer to the Symptom
Chart: NVH.
To maximize tire performance, inspect for signs of incorrect
inflation and uneven wear, which may indicate a need for balancing,
rotation or front suspension alignment.
Correct tire pressure and driving techniques have an
important influence on tire life. Heavy cornering, excessively rapid
acceleration and unnecessary sharp braking increase tire wear.
