B350 1 Ton Van V8-5.9L VIN Z (1992)
Intake Manifold: Description and Operation
The iron intake manifold is water cooled. The manifold provides for single plane air/fuel induction, exhaust heat and coolant (thermostat water box)
crossover. The unit is also cored with passages to route METERED coolant below the exhaust heat crossover and through the manifold. This metered
coolant flows through the right and left manifold side gaskets. The sealing of the manifold is accomplished by steel embossed side gaskets with front and
rear rule die cut (cork and hypalon) gaskets. The intake manifold is also cored with upper level EGR passages for balanced (cylinder to cylinder) EGR
distribution.
