The EGR valve and the electric EGR transducer
(EET) are serviced as one unit.
(1) Disconnect vacuum hose to EGR valve/trans­
ducer assembly. Note position of hoses on EGR valve
and transducer for easier installation.
(2) Remove EGR mounting bolts (Fig. 5).

(3) Remove EGR valve and gasket. Discard old
gasket. Clean intake manifold mating surface and
check for cracks.

INSTALLATION
(1) Place new EGR gasket on intake manifold. (2) Install EGR valve. Tighten mounting bolts to
23 N*m (200 in. lbs.) torque. (3) Connect vacuum hose to valve/transducer as­
sembly.

TUBE-GAS POWERED ENGINES

REMOVAL
(1) Remove air filter housing.
(2) Remove the spark plug cable loom and plug ca­
bles from valve cover mounting stud at rear of right
valve cover. Position spark plug cables to top of valve cover.
(3) Disconnect two vacuum hoses at exhaust gas
recirculation (EGR) valve. (4) Remove 2 EGR valve mounting bolts (Fig. 5)
and remove EGR valve. Discard old gasket.
(5) Disconnect electrical connector at engine oil
pressure sending unit.
(6) To prevent damage to oil pressure sending unit,
a special tool, such as number C-4597 must be used
(Fig. 6). Remove sending unit from engine.
(7) Loosen EGR tube mounting nut at intake man­
ifold (Fig. 7).

(8) Remove EGR tube mounting bolts at exhaust
manifold (Fig. 7) and remove EGR tube.

INSTALLATION
(1) Clean the EGR tube and exhaust manifold (at
EGR tube mounting point) of any old gasket mate­

rial.
(2)
Install a new gasket to exhaust manifold end of
EGR tube. (3) Install EGR tube to both manifolds. Tighten
mounting nut at intake manifold. Tighten two
mounting bolts at exhaust manifold to 23 N»m (204 in. lbs.) torque.
(4) Coat the threads of the oil pressure sending
unit with thread sealant. Do not allow any of the
thread sealant to get into the sending unit opening
or the opening at the engine. Install sending unit to

Install electrical connector to sending unit.
(5) Clean the intake manifold and EGR valve of
any old gasket material.
(6) Install a new EGR valve gasket to intake man­
ifold. (7) Install EGR valve to intake manifold. Tighten
two mounting bolts to 23 N*m (200 in. lbs.) torque.
(8) Install vacuum lines to EGR valve.
(9) Install spark plug cable loom and plug cables to
valve cover mounting stud.
(10) Install air filter housing.

ELECTRIC EGR TRANSDUCER
(EET) The EGR valve and the EET are serviced as one
unit. Also refer to EGR valve removal/installation.

REMOVAL
(1) Remove air filter housing.
(2) Disconnect wiring connector at EET (Fig. 8). (3) Disconnect hoses at EET. Note position of hoses
for easier installation.
(4) Remove EET from engine.
