Well if the temps aren't warm enough the fans won't turn on again, so that's a likely situation you have going.

If the fans stayed on and never stopped that points to the new temp sensor being faulty. The fans also come on with the AC, so you could hit the AC button and see if they work.


Check fuses and if the temp sensor you bought was some aftermarket brand I would replace it with a AC DELCO part only. Then bleed the cooling system again.
