INTAKE MANIFOLD
REMOVAL & INSTALLATION
When servicing all vehicles, be absolutel y sure to mark vacuum hoses and
wiring so that these items may be properly reconnected during installation. Also,
when disconnecting fitting lines (fuel lines, power brake vacuum lines,
transmission and engine cooler lines, etc.), always use two flare nut (or line)
wrenches. Hold the wrench on the large fitti ng with pressure on the wrench as if
you were tightening the fitting (clockw ise), THEN loosen and disconnect the
smaller fitting from the larger fitting. If this is not done, damage to the line will
result. Always relieve fuel system pressure before disconnecting lines.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.

When servicing the engine, be absolutely sure to mark vacuum hoses and
wiring so that these items
may be properly reconnected during installation. Also,
when disconnecting fittings of metal lines (fuel, power brake vacuum), always
use two flare nut (or line) wrenches. Ho ld the wrench on the large fitting with
pressure on the wrench as if you were tightening the fitting (clockwise), THEN
loosen and disconnect the smaller fitting fr om the larger fitting. If this is not
done, damage to the line will result.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.

ENGINE RECONDITIONING DETE RMINING ENGINE CONDITION
Anything that generates heat and/or friction will eventually burn or wear out (i.e.
a light bulb generates heat, therefore its life span is limited). With this in mind, a
running engine generates trem endous amounts of both; friction is encountered
by the moving and rotating parts inside the engine and heat is created b\
y
friction and combustion of the fuel. Ho wever, the engine has systems designed
to help reduce the effects of heat and fr iction and provide added longevity. The
oiling system reduces the amount of fr iction encountered by the moving parts
inside the engine, while the cooling system reduces heat created by friction and
combustion. If either system is not main tained, a break-down will be inevitable.
Therefore, you can see how regular main tenance can affect the service life of
your vehicle. If you do not drain, flush and refill your cooling system at the
proper intervals, deposits will begin to accumulate in the radiator, thereby
reducing the amount of heat it can extrac t from the coolant. The same applies to
your oil and filter; if it is not changed often enoug h it becomes laden with
contaminates and is unable to properly lubricate the engine. This increases
friction and wear.
There are a number of methods for evaluat ing the condition of your engine. A
compression test can reveal the condition of your pistons, piston rings, cylinder
bores, head gasket(s), valves and valve seat s. An oil pressure test can warn
you of possible engine bearing, or oil pump failures. Excessive oil consumption,
evidence of oil in the engine air intake area and/or bluish smoke from the tail
pipe may indicate worn piston rings, worn valve guides and/or valve seals. As a
general rule, an engine that uses no more than one quart of oil every 1000
miles is in good condi tion. Engines that use one quart of oil or more in less than
1000 miles should first be checked for oil leaks. If any oil leaks are present,
have them fixed before dete rmining how much oil is consumed by the engine,
especially if blue smoke is not visible at the tail pipe.
COMPRESSION TEST
A noticeable lack of engine power, excessive oil consumption and/or poor fuel
mileage measured over an extended period are all indicators of internal engine

EVAPORATIVE EMISS
ION CONTROLS
OPERATION
This system reduces the amount of gasoline vapors escaping into the
atmosphere. Some models em ploy a purge control solenoid which is controlled
by the ECM, to open and close the EE C system. Other models use a canister
mounted vacuum purge valve; when the engine vacuum reaches a certain
pressure, the valve opens allowing the gas vapors to be drawn off to the
carburetor for burning.
Carbureted models use an exhaust tube fr om the float bowl to the charcoal
canister; fuel injected models eliminate the fuel bowl tube (as no float bowl is
used on fuel injection systems). Fuel vapor s from the gas tank travel from the
tank to the vapor canister , where they are collected. Although the system varies
from vehicle-to-vehicle, the operat ions are basically the same.
