I have done the regular maintenance on the car threw the years ....I also flush the radiator in the past and I did bleed the system everytime I replaced a hose and when I did the water pump and thermostat..The car has a electric water pump so I just step on the gas pedal for over 10 sec till the pump come on and I let it run for 15- 20 min.. Can a defected heater control valve cause the hoses to keep busting? I replace the valve but I wonder if it's defected..
