Is there a bleed off valve on the coolant system for this model and engine?

There was no problem before I had to change the fan assmbly or radiator, o e of the fan blades broke and gouged holes in the radiator. Just wondering, how would that affect the thermostat?

Coolant acts as a lubricant for moving t-stat parts .. Coolant was lost .. T-stat may be sticking. Why does anything stop working at any given time? .. It is an online best guess.. I have to assume if it was an air pocket issue that should take care of itself since the coolant fill is @ highest point... Make sure coolant level is still full after vehicle sits overnight... Good luck with it! ▪️https://repairpal.com/repair-shops▪️
