Engine
injected into the exhaust ports near
each exhaust valve. The oxygen in
the air plus the heat of the exhaust
gases in each exhaust outlet port in-
duces combustion during the exhaust
stroke of the piston. The burned gases
then flow out the exhaust manifolds
into the exhaust system.
The Thermactor system consists of:
an air supply pump; an air bypass
valve; check valves; an air supply tube
to the exhuast port of each engine
cylinder; air manifolds for the cylin-
der heads on the 302 V-8 engines;
upper air supply tube assemblies; and
the connecting air supply hoses .and
'vacuum sensing hose.
A sectional view of the air bypass
valve is shown in Fig. 14. The Ther-
mactor system is shown installed in
Fig. 15.
Air under pressure from the pump
flows through the bypass valve, to the
exhuast ports of the cylinder heads. A
check'valve in the inlet. air side of each
air manifold or air supply tube assem-
bly prevents a backflow of exhaust
gases into the air pump assembly
when the exhaust back pressure ex-
ceeds the air pump delivery pressure.
All the air from the air supply
pump passes through the bypass valve.
Normally, the air is directed to the
check valve and into the cylinder
heads. During engine deceleration pe-
riods, air delivery to the cylinder
heads is momentarily interrupted and
the air is diverted to the atmosphere.
2 IN-VEHICLE ADJUSTMENTS AND REPAIRS
When installing nuts or bblts that
must be torqued (refer to Part 8-5
for torque specifications), oil the
threads with light weight engine oil.
Do
not oil threads that require oil-
resistant or water-resistant sealer.
Refer to Part 8-1, Section 3 for
cleaning and inspection procedures.
Refer to Part 8-1. Section 1 for
test procedures.
ENGINE FRONT SUPPORT
INSULATORS
The front supports are located on
BOLT-20386s
each side of the 'cylinder block (Figs.
16 and 17). The procedures given ap-
ply to either a right or left installation.

Removal
1. Attach engine mount t o brack-
et with long bolts and nuts. Torque to
specifications.
2. Install engine moun~/bracket
assembly.
3. Install bolts and washers at-
taching engine mount brackets to side
supports. Torque bolts to specification.
4. Install bolts and washers at-
taching engine mount to engine. Tor-
que bolts to specifications.
1. Support the engine with a jack
and a piece of wood placed under the
oil pan.
2. Remove the insulator assembly
to support bolt, washer and nut from
both front supports.
.-
3. Using the jack and block of
wood placed under the oil pan, raise
the engine enough to allow for re-
rnoval of the insulator assembly.

sembly to the engine.
Installation
1. Place the insulator assembly in
position on the engine block and in-
stall the bolts and washers. Torque
the bolts to specifications.
2. Lower the engine enough to
allow installation of the insulator
assembly to support bolt washer and
