If Thermostat goes bad after doing a Radiator flush can the Flush be the culprit, or it was about to happened anyway.

What are the signs if Thermostat goes Bad but Water pump is OK ?

If Thermostat goes bad should the Water pump be the Next to go also. ?

Thermostats are designed to fail in the open position, meaning that the car would be very, very slow to warm up. You can tell by the lack of hot air thru the heater in cold weather.
