Using an 8mm socket, remove the two 6mm

housing aside to be reused later. Leave the facto-

ry thermostat and O-ring seal in place as they will

be reused (provided they are in good condition).

(See Fig. 5.2-a.)

Locate the supplied thermostat housing adaptor

and hardware. Using the two 6mm socket-head

screws, install the housing adaptor as shown.

(See Fig. 5.2-b.)

Using the 6mm hardware, washers and

O-ring provided, reinstall the thermostat housing.

Attach the previously removed resistor to the

housing as shown. (See Fig. 5.2-c.)

Reinstall the intake manifold removed in a previ-

ous step. Check to see that the rubber intake run-

ner gaskets are in place and undamaged. Make

sure the cylinder head surface is clean.

Lower the intake manifold onto the cylinder heads.

Install the ten factory 10mm headed manifold

retainers, and tighten to factory specifications.

Remove the small clips that retain the factory fuel

injectors to the fuel rail. Remove the factory fuel

injectors and set aside. These will not be reused.

Locate the supplied fuel injectors. Lubricate the

injector O-rings with clean motor oil and install

into the fuel rail. Reinstall the small retaining clips

onto the injectors.

Lower the fuel rail/injector assembly onto the

manifold, making sure that the injectors seat prop-

erly into the manifold. Secure with the four factory

8mm headed bolts.

Reconnect the fuel injector plugs, all other con-

nections and vacuum lines previously removed

from the manifold assembly.
