Coolant Manifold Removal
[215 NK]
Refer to Figure 91.
1. Disconnect wires to dash gauge and
V-MAC III coolant temperature sensors, and
boost air temperature sensor. Position wires
out of way.
2. Disconnect and remove line between
coolant manifold and water pump.
3. Support the coolant manifold sections and
remove 12 capscrews (5) retaining the
manifold sections (1 and 4) to the cylinder
heads.
The hex-head capscrews and washers used to
attach the manifold on early-production engines
are replaced by flangehead capscrews in later
production.
4. Remove manifold assembly. It may be
necessary to pry or tap lightly with a soft
mallet on the housing sections to break the
seal.
5. If necessary, separate the two coolant
manifold sections (1 and 4) by loosening two
clamps (3) and removing the coupling (2).
6. If the coolant manifold is to be replaced,
remove sensor located on the manifold (4).
