my 1995 mazda mx6

Hey guys I have a 95 mazda mx6 and the radiator hose on the top squeezes in or gets sucked in when you crank it up, and expands again when you turn it off. can somebody help me out?

First, replace the hose because its integrity is questionable after flexing like that.
While you are at it, replace the thermostat.

I always drill a bypass hole in thermostats for extra flow insurance. Sounds like yours is clogged; the factory solution is a hole with a loose rivet in it. They clog.

If you don't have "some" flow when the T-stat is closed (engine is cool), it will collapse that hose. Some water pumps also have an external diverter hose. I don't know if yours does or not.
