PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
● When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
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.
● Replace with new liquid gasket, packing, oil seal or O-ring.
● Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
● Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
● Release air within route when refilling after draining engine coolant.
● Before starting engine, apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine
stopped). Then make sure that there are no leaks at fuel line connections.
● After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil and
exhaust systems for leakage.
Parts Requiring Angle Tightening ABS005ZP
● Use an angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
– Cylinder head bolts
– Main bearing cap bolts
– Connecting rod cap bolts
– Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angle
tightening)
● Do not use a torque value for final tightening.
● The torque value for these parts are for a preliminary step.
● Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid Gasket ABS005ZQ
REMOVAL OF LIQUID GASKET SEALING
● After removing mounting bolts and nuts, separate the mating
surface using a seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
● Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.
● In areas where seal cutter is difficult to use, use plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove old liquid gasket adhering to liquid gas-
ket application surface and the mating surface.
● Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe liquid gasket application surface and the mating surface
with white gasoline (lighting and heating use) to remove adher-
ing moisture, grease and foreign materials.
