PRECAUTIONS BEFORE SERVICE
m i
PROTECTING THE VEHICLE
If there is a likelihood of damaging painted or interior parts
during service operations, protect them with suitable covers
(such as seat covers, etc.).
> ’
REMOVAL AND DISASSEMBLY
When checking a malfunction, find the cause of the problem.
If it is determined that removal and/or disassembly is neces-
sary, perform the work by following the procedures con-
tained in this Service Manual.
If punch marks or mating marks are made to avoid error in
assembly and facilitate the assembly work, be sure to make
them in locations which will have no detrimental effect on
performance and/or appearances.
If an area having many parts, similar parts, and/or parts
which are symmetrical right and left is disassembled, be sure
to arrange the parts so that they do not become mixed during
the assembly process.
1. Arrange the parts removed in the proper order.
2. Determine which parts are to be reused and which are to
be replaced.
3. If bolts, nuts, etc., are to be replaced, be sure to use only
the exact size specified.
SPECIAL TOOLS
If other tools are substituted for the special tools to do serv-
ice or repair work, there is the danger that vehicle parts might
be damaged, or the mechanic might be injured; therefore,
be sure to use the special tool whenever doing any work for
which the use of one is specified,
