Why is coolant not flowing?

Why is coolant not flowing?

Blockage In Cooling System. If the coolant is not freely circulating through the system there is a possibility that the thermostat is not working properly and is stopping the flow. Another possibility could be blockage in the radiator or in the tubes connecting to the inlet or outlet tank at the end of the radiator.

Can’t find a coolent leak?

To locate a coolant leak, first look for puddles of coolant beneath your vehicle. If you see any, you probably have fluid dripping from somewhere in the system. With the car’s engine running, look under the hood to see if you notice any fluid flowing out. If you do, trace the fluid to its source.

What controls the coolant flow through a radiator?

Once the coolant reaches the thermostat’s activation temperature, it opens, allowing water to flow through the radiator to prevent the temperature rising higher. Once at optimum temperature, the thermostat controls the flow of engine coolant to the radiator so that the engine continues to operate at optimum temperature.

What causes oil to leak into the radiator?

If the gasket blows, the engine oil will enter the coolant passages causing the engine to fail. Moreover, damage to the cylinder connected to the engine block may cause the oil to seep into the radiator.
