Where does the coolant go in a Pontiac engine?
Openings in the water distributing tube direct coolant in jet fashion onto valve seats and around each exhaust passage. This feature is referred to as “gusher valve cooling”. The combination of reverse flow circulation and gusher valve cooling results in relatively low operating temperature of valves and valve seats.
Where does the water go in a 1956 Pontiac?
Water circulation during warm-up (thermostat closed) is from the pump to the water distributing tubes to the cylinder heads, [[1956 engine]] down into the block and back to the pump through passages from the front of each bank to the water pump inlet (Fig. 6A-1).

Where does the water go in a Pontiac radiator?
Part of the water will always recirculate through the block as outlined above. A large portion of the water, however, will pass from the pump to the water distributing tubes, to the heads, and thence directly into the top of the radiator through the water outlet page in the front of the intake manifold.
Where does the coolant go in a water pump?
Inside the pump is an impeller (which might be made of either metal or plastic) with blades that push the coolant through the pump and out around the engine. The impeller is then mounted on a shaft with a seal assembly supporting it and allowing it to work without being impeded in any way.

Where are the cooling ports on a 1960 Pontiac?
Ports towards front and on bottom of deck are smaller on the 1960 block than the reverse flow blocks. This obviously is to force more water to the back of the engine and to lower side of heads to provide controlled cooling for the 1960 engine.
