Incorrect.

The only way you would not have over heating problems if it WAS stuck open is if you were on the highway all the time while driving.And if that WAS the case you would see lower temps then the 160* that he reported.

The whole point of a radiator is to hold the water,Then cool it BEFORE it enters the engine.

If the fans could do the job of cooling all that water by itself then anyone could take there thermostat out in any car and have 0 issues.
