Why does water/coolant leak from my 1995 Chevy Corica from what appears to be a drain hose on the firewall behind the engine
I've recently gotten a 1995 Chevrolet Corsica from my sister. Today I noticed water leaked from a hose at the firewall. I drove the car 17 miles today and it didn't run hot. It appears that the water leaks mostly when engine isn't running If I let the car sit for a while and then drive (without adding water) the engine will begin to run hot and the heater begins to stop working, but as soon as I add water, the engine immediately cools down and heater works great?
