  1. It does not overheat when i drive. Gauge usually stays at 12:00.
  2. The cap is not new pure water has been used water pump belt is good does not have any leaks upper hose does get hard the water concentration bubbles out of the expansion tank whenever car is at idle or turned off after being driven.
  3. Whereever the car is in idle, water backs out through the cap on the coolant tank. Even when i turn the car off. It usually empties out the coolant tank.
  4. My drivers window will not go up. A few days ago on the driver's side window switch I could roll down the front passenger window and the driver's side rear passenger window, but I could roll them up. Now nothing works on the entire driver's side door panel. Not even the door locks. But the other windows still work.
