It sounds like an overheating problem more than a fan problem. When did this start happening?

How old is the coolant surge tank cap? If unknown, replace it and see if it happens again. The cap is need to pressurized the coolant system, if the cap fails, the coolant WILL boil over.

This issue has started since weather has gotten warm. I have replaced themostat and new 50/50 coolant.

Replace the coolant cap as mentioned above and see if problem continues.

Hi All, I have installed the new radiator cap and have had zero problems the last 2 days with boiling over after stopping and the fan is now running after car has been turned off. Temps have been over 110 degrees here in Las Vegas. Again I have to say thanks to everyone who game me advise on how to fix this issue. Now its on to the AC.
