Dear all friends i know its very hot here in lahore, today and yesterday i have notice that boiling water noise coming from bottle and radiator then i checked it was boilong and i m using ZIC coolant with water. Plz guide what i have to do....
just check water lever after every day... If you feel that water level decrease very much.. if so , then check you car with rediator wala
Get your radiator serviced
the coolant should never boil over, the pressure cap is there to raise boiling point of the coolant. If you are facing boil over in the expansion tank by pressure from the radiator then you have a leak in the cooling system.
radiator may need Cleaning simple as That
Radiator already serviced in March 2012
replace the radiator cap, its not building up pressure in the radiator and soon you will start to lose coolant from the bottle
But water and coolant decressing in bottle 1st and them in radiator and boiling voice coming from bottle. today its hapening the same yesterday i have change the water and coolant from radiator and put new coolant of guard with water but nothing is changed.
there is surely some air in your cooling system, USE search option for flushing cooling system and there is a thread posted by GURU Xulfiqar how to flush & fill the cooling system afterwards.
