88 fan issues
Motor fan comes on at 225* fan before it (single) seams like it never does or at least I haven't got to the temp that it should...should I be worried ?? I changed from 165* thermostat and a Hyper chip back to stock because I was having all sorts of other issues.Thanks in advance

GM says fan goes on at 228 F and off at about 210 F. Aux fan goes on at 238 F. These temps will harm nothing in the engine are nothing to worry about whatsoever. GM says to shut the engine off at 260 F and let it cool down. This is because 50% antifreeze at 15 psi boils at 265 F and boiling antifreeze can cause head damage because boiling antifreeze is a poor heat conductor.
