ok so a little over a week i replaced my radiator hoses cause one popped and after doing so everything was ok now i bought

now a new head did the gasket just cause i had the spar money
now i got a new problem just got out of the shop and drove a little ways home and started to heat up and when i got home my overflow was boiling hot and gurgling water \

my question is my fan is hot wire so it is on all the time the guy that drove it drove a lot of miles a day and in traffic now with that being on how well do the stock fan motors hold out and is there a way to test if there dieing don't want to go out and just get one cause there pricey so let me know what you think rep will be given
