Every time I put coolant or water it leaks out from the bottom area of car. The reservoir itself is not leaking. It's coming from somewhere else. When running the car engine overheats and engine runs idle. What can be causing this problem?

Welcome to 2CarPros.

Coolant can be leaking from several different places. A bad radiator hose, water pump, radiator itself, heater hose, and so on. What you need to do is have someone pour coolant into the reservoir while you watch to see where it is leaking from.

Now, here are a few links that should help you locate the leak. Once you locate it, let me know where it's coming from and I will direct you on fixing it. The first link shows specific places to check. The second link may not help. It explains how to pressurize the system to locate a leak. However, it may be required.

Follow the links and see if you can located where the leak is coming from. If you see it and can't identify the part, take a pic of the leak and upload it for me to see.

Take care,
