Best answer


All the coolant flows to therear of the block,where large main coolant passages allow the coolant to flow across the head gasket. The coolant then enters the rear of the heads. In the heads,the coolant flows forward to a crossover passage on the intake manifold outlet at the highest point in the engine cooling passage.

  • Where does the coolant go when the engine is cooled?

  • The flow of coolant will either be stopped at the thermostat until the engine is warmed, or it will flow through the thermostat and into the radiator where it is cooled and the coolant cycle is completed. Reddit! Apr 2002 San Jose 40 2,050 Red

  • How does an engine coolant pump work?

  • A pump , driven by a pulley and belt from the crankshaft , drives hot coolant out of the engine to the radiator , which is a form of heat exchanger . Unwanted heat is passed from the radiator into the air stream, and the cooled liquid then returns to an inlet at the bottom of the block and flows back into the channels again.

  • How does a water cooled engine cool the engine?

  • Generally this is done by circulating coolant liquid usually water mixed with an antifreeze solution through special cooling passages. Some engines are cooled by air flowing over finned cylinder casings. A typical water-cooling system with an engine-driven fan: note the bypass hose taking off hot coolant for the heater.

  • Where does the thermostat connect to the coolant?

  • The thermostat is connected to the lower radiator hose blocking coolant from entering the block until the engine is warmed. Until the thermostat opens, coolant is not moving through the radiator but is still being cooled by air flow through it (especially for you guys up north in the winter).
