There is a small hose not to far from coolant tank but right next to water pump...does anyone knows what kind of hose that is. Mine is spraying coolant everywhere.

 

sippigrl86, what you are saying could be a few hoses as you have hoses for the throttlebody and for the heater core along with some normal coolant hoses for the motor. If you could say where one end of the hose runs, that would give us a better idea of what hose you are talking about. It is a large 1" hose or is it something more in the neighborhood of a 1/2" hose?

 

If it's "spewing coolant", it must be one of the coolant hoses. On your car, is it the one shown on this thread?
