PRECAUTIONS
PRECAUTIONS PFP:00001
A
Precautions for Drain Engine Coolant ABS00A7M
Drain engine coolant when engine is cooled.
EM
Precautions for Disconnecting Fuel Piping ABS00A7N
q Before starting work, make sure no fire or spark producing items are in the work area.
q Release fuel pressure before disconnecting and disassembly. C
q After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and Disassembly ABS00A7O
D
q When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.
q Exercise maximum care to avoid damage to mating or sliding surfaces. E
q Cover openings of engine system with tape or equivalent, if necessary, to seal out foreign materials.
q Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.
q When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally F
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be
used in the step.
Precautions for Inspection, Repair and Replacement ABS00A7P G
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
H
Precautions for Assembly and Installation ABS00A7Q
q Use torque wrench to tighten bolts or nuts to specification.
q When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the I
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.
q Replace with new gasket, packing, oil seal or O-ring. J
q Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
q Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. K
Before assembly, oil sliding surfaces well.
q Release air within route when refilling after draining engine coolant.
q After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and L
exhaust gases for leakage.
Parts Requiring Angle Tightening ABS00A7R
M
q Use angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
