Cooling system question
Would my fan going on and off at high speed every 5 mins mean waterpump failing? If so when changing the waterpump and thermostat what else should be change ?

Could be your temp sensor that controls the fan. It's on the passenger side coolant return line down low on radiator, it just snaps in. Usually when these fail, the fan defaults to high speed so it could be going out on ya. Super easy to replace
