What percentage of American children live in poverty? According to the National Center for Children in Poverty, 16 percent of children (20 percent of children under age six) in America live in poverty. The child poverty rate in America is often two to three times higher than that of other major industrial nations. Poverty is defined as living in families with incomes below the federal poverty line ($21,200 for a family of four in 2008).
The main cause for tire cupping is worn suspension allowing too much freedom for the wheel to bounce and vibrate, specifically shocks/struts and bushings. If your wheels are going out of balance, this issue is greatly amplified.
When the gasket fails, coolant comes out of what is called a weep hole. If you don't replace the water pump, the bearing gets saturated with coolant and fails. When the bearing fails, the water pump pulley ceases and the belt fails. I have seen this too many times. That fan thing is called an impeller and when it spins it pumps coolant through the motor and radiator to keep it cool.
