Have an 03 chevy impala runs hot but radiator cap is cold can put water in it and leaks out

What is your question? You should not operate a vehicle that overheats. You should not put just plain water in a cooling system for a car. You can see the leak? You should get it fixed before any more damage happens to the engine. Failure to keep the engine cool can cause a host of problems and none of them are cheap to fix.

Gauge shows hot and loses coolant

Suspect you have a loose clamp on a radiator hose or the oil change guy made something leak. There is a tool which is similar to a a bicycle pump in that it pressurizes the water system and your engine does not have to run or be hot to test. Some major auto parts stores may have a loaner.

Its going to stay hot and lose pressure until you fix the leak.

That could be a bad lower intake manifold gasket. Have it checked by a mechanic as soon as possible; left unfixed, it could quickly destroy your engine.

2003 chevy impala ls starts then stalls

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.
