What kind of water pump does a Boss 302 have?
Beginning in 1970, 302 and 351W small-block Fords received a new water pump casting (D0AZ-8501-C) with the inlet on the left-hand side of the engine. Boss 302s for 1969 were fitted with a 1969- specific high-flow water pump (C9ZZ- 8501-A).
How does a bypass valve work on a thermostat?
But a completely separate spring loaded bypass valve (B) independently controls the bypass. The way this works is that when the thermostat is closed, it arrests flow, which creates a local area of high static pressure. This pressure opens the bypass valve, allowing coolant to recirculate to the pump (P) and back to the engine (E).

Is the bypass passage always open or closed?
With this system, an unrestricted passage through the head or block routes hot coolant back around to the pump inlet. As the name implies, the bypass passage is always open. It may seem as if at least half the coolant will flow through the bypass at all times. But the physical layout is important.
Can a bypass valve be opened on a water softener?
If your water softener uses an external bypass valve (the lower plumbing design in our sketch), CLOSE the inlet and outlet valves and OPEN the bypass valve that in essence is a shunt that bypasses the water softener. Watch out: put the water softener in bypass mode only when repairs are needed.

How is the Culligan bypass valve in a water softener valve operated?
The Culligan bypass valve shown above is operated simply by pushing in on the valve end whose valve stem is visible – or in the “out” position. Our pen is pointing to the valve stem.
What kind of bypass valve does a water conditioner use?
Some water conditioners such as the Autotrol Series 255 use a different (and optional) bypass valve that has two individual knobs that must be turned to switch between in-service and bypass modes – shown at below-left. The sketch above shows the optional Autotrol Series 255 Valve / 460i bypass valve.
