Thanks again for taking the time to respond. First, the brown fluid I mentioned leaks right in the center between the driver and passenger side of the engine bay. It occurs right below the firewall, just before the torque converter. Second, the cracked hose I mentioned comes out from the neck of the coolant reservoir and goes back under front passenger side fender. It haven't had a chance today to see where that hose goes. Like, I mentioned in my first post, I've been smelling coolant for the last one week. I opened the hood and I couldn't tell where the smell was coming from and couldn't see any leaks. Someone at work suggested that it could be the heater core. Hope this helps.
