Fl6 volvo overheating 2003.engine is boiling - Volvo Cars & Trucks

When an engine is on full bore and pulling hard it is using more fuel and consequently produces a lot more heat - at least 60% of the fuel used is turned into heat; fortunately most of it is ejected through the exhaust though a significant amount is radiated from the metalwork of the engine and ancillaries and sent into the fuel tank through the return line (keep the tank more than a quarter full) and that still leaves a considerable amount of heat to be dissipated by the radiator.
The situation is made worse as uphill travel is at a lower road speed and therefore there is less ram air effect on the radiator and the cooling fan is left to do all the work.

The principle cause of a failure to dissipate the heat is either insufficient airflow through the radiator, insufficient coolant circulation or a combination of both.

Assuming coolant loss isn't the cause of overheating...
While it isn't unknown for a water pump to lose a vane and it is far from unknown that a defective thermostat can be a cause of overheating, the common cause of reduced coolant circulation is a partially blocked radiator core.

Reduced airflow is commonly caused by mud and insects clogging the radiator gills, mechanical damage to the gills, slipping drivebelts, defective viscous or thermal fan drives, inoperative electric fan, forgotten winter radiator masks...
It is also not unusual for a fan cowling to be omitted during service in order to make subsequent work easier - fan cowlings are important...
