6-1-4 ENGINE GENERAL INFORMATION AND DIAGNOSIS (H25 ENGINE)
General Information
Statement of Cleanliness and Care
An automobile engine is a combination of many machined,
honed, polished and lapped surfaces with tolerances that are
measured in the thousands of an millimeter (ten thousands of
inch). Accordingly, when any internal engine parts are serviced,
care and cleanliness are important. Throughout this section, it
should be understood that proper cleaning and protection of
machined surfaces and friction areas is part of the repair proce-
dure. This is considered standard shop practice even if not specif-
ically stated.
• A liberal coating of engine oil should be applied to friction
areas during assembly to protect and lubricate the surface
on initial operation.
• Whenever valve train components, pistons, piston rings, con-
necting rods, rod bearings and crankshaft journal bearings
are removed for service, they should be retained in order. At
the time of installation, they should be installed in the same
locations and with the same mating surfaces as when
removed.
• Battery cables should be disconnected before any major
work is performed on the engine. Failure to disconnect
cables may result in damage to wire harness or other electri-
cal parts.
• Throughout this manual, the 6 cylinders of the engine are
identified by numbers; No.1, No.2, No.3, No.4, No.5 and No.6
as counted from crankshaft pulley side (9) to flywheel side.
