The ford f150 4.6 cooling system consists of the radiator, water pump, thermostat, and coolant reservoir. coolant flows through hoses and passages, absorbing heat from the engine and carrying it to the radiator for cooling. the water pump circulates the coolant, while the thermostat controls its flow based on the engine’s temperature. 7.3 powerstroke coolant flow diagram. the powerstroke 7.3 is a workhorse engine that was used in ford super duty trucks from 1999 to 2003. this engine is known for its durability and longevity, but it can still have cooling system issues. the coolant flow diagram for the 7.3 powerstroke can help you troubleshoot any problems you may be having. No flow means the coolant in the engine is just getting hotter and hotter. this, combined with any air in the system, will create a back pressure that can force coolant out into the overflow tank. this is just a theory, of course. anyway, you're probably on the right track to replace the thermostat and water pump.
