Summary:
Last week I received a low engine coolant light. I filled the coolant. The next day I removed the coolant cap to check the level and most of the coolant I put in overflowed. Took it to the dealer and they found two leaks in the hose. Dealer called me today and said my heater isn't working and says I need to repair my heater coil to the tune of several thousand dollars. I have no mechanical experience so I'm hoping forum members can help. All advise is appreciated.
