Why the car gets over heated?

Answer 1

if you are talking about engine overheating possibly you have problem with your cylinder head. sometimes due to natural wear and tear gasket in the cylinder head got blown and the pressure of the engine is going inside the cooling system making the engine to overheat since when the pressure is high water from the radiator will be expelled to the radiator reservoir causing overflow that lessen the cooling water inside the engine. you can check it by having somebody start the car ( while engine is cold ) prior to start up remove radiator cap, upon start check if the water in the neck of the radiator opening will spill out. if it does probably you've got a blown head gasket. Have it replace by your mechanic. have the mechanic check also the thermostat of your cooling system, there's probability that it is not working properly. Have the water pump also be check whether it is still working or not. Have the clutch fan be check for its proper operation. You can check it while engine is cold, rotate the fan blade of the radiator fan. if the clutch fan is still good it should not turn half of its radius. if you can easily turn it then its time to replace it.
