7. Disconnect the fuel lines at the inlet and
outlet ports at the top of the cooling plate
(Figure 133) and position the lines
out-of-way.
Use care when disconnecting the fuel lines to
avoid putting stress on the plate fittings and
damaging the plate. Use two wrenches, one to
support the plate fitting and the second to
disconnect the line.

8. Loosen the two retaining nuts securing the
plate support bracket to the mounting studs
on top of the coolant manifold. The bracket

not removed.
9. Remove the two retaining nuts from the
mounting studs at the bottom of the cooling
plate and remove cooling plate assembly.
