Any suggestions? Just want to make sure I’m barking up the right tree before I drop some cash on a new part. I plan on fixing it myself.

Please define "overheating". Is it boiling over or is the temp. just going up? It's normal for the temp to increase at idle and low speed driving, particularly in warm weather.
Does the engine have and electromagnetic fan clutch ofra themo fan clutch? At about 100C the engine fan should engage via either the electomagnetic clutch or the thermo clutch. At about 105C the electric fan should engage at high speed.
