Q: Car lost power steering, leaking coolant.

Hello it sounds like you have two problems here. Both of theses should be handled sooner than later. For the power steering the fluid level should be checked and see if the belt is on the pulley. If the fluid level is low, fluid needs to be added and the leak needs to be located. A pump that runs dry can cause internal damage and put metal shavings in the power steering fluid system. With a belt missing, a belt must be installed and cause for the belt failure should be found unless the belt was old and broke. If the belt is on and the fluid level is ok there is a good chance that the pump has failed and will need replacement. A coolant leak can lead to an overheating engine that can lead to a blown head gasket. You will need to enlist the aid of a mechanic who can pressure test the cooling system, and locate the coolant leak and the loss of power steering.
