My 3L toyota hiace keeps on boiling and the water pump is not working. I have replaced the pump, Head and gaskets but all in vain. Am i missing some secrets with this particular type of engine?

Yeah. Boil/ Flush Out the Cooling System & Replace thermostat, Are you running 50%-50% Anti-Freeze & Clean Water= Coolant? Are the Radiator & A/ c Fans Working Properly (Radiator Fan Cycling as Engine Heats & Cools, A/ C Fan Condenser/ Radiator on at all times with A/ C on)? Radiator Surface is Clean & 90% of Fins are Straight for Max. Airflow? Radiator Hoses & Clamps could be damaged from Overheating so many Times.
