Water Pump Flow Diagram
This provides the passenger compartment with heat and defrost.
Water pump flow diagram. If not the structure won t work as it should be. Jet pumps are mounted above the well either in the home or in a well house and draw the water up from the well through suction see single drop jet pump system diagram on next page. Here is the coolant flow cycle as described in the service manual for the ls2. I suggest you google fresh water cooling diagram for your particular when the thermostat is open the valve closes and the water flows nov 09 the flow diagrams shown are different from mine as they show two hoses from the intake raw water one leading to the stat and one going to the pump for the exhaust maniflods where mine on the only.
With centrifugal impellers restricting the flow rate with a valve reduces the power required proportionally. As the pump pressure increases the weight of the water being lifted is reduced and the power required decreases. With these type pumps the excess backpressure created by choking a pump with a valve is a free by product of horsepower. Some coolant will then be pumped from the water pump to the heater core then back to the water pump.
Coolant is also pumped through the water pump outlet and into the engine block. Cooling cycle coolant is drawn from the radiator outlet and into the water pump inlet by the water pump. Some coolant will then be pumped from the water pump to the heater core then back to the water pump. The ls3 should be the same.
