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 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.
How did the Pontiac V-8 engine get cooled?
Beginning with the first production engines in 1955, Pontiac V-8 engines were cooled by reverse flowmeaning the cooling water enters and cools the heads first and then some of the water enters the block and cools the
Why is my Pontiac engine not cooling properly?
As displacement got larger, compression went higher, and engine heat increased to get better performance, it may be that the cylinders were getting inadequate cooling – which would likely not show up on the temp’ gauge but would show up as piston failure in “stressed” engines.

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.
