Asked by Mann3682 Nov 10, 2018 at 02:09 PM about the 2006 Buick Lucerne CXS FWD

Question type: Maintenance & Repair

My coolant keeps bubbling when I come to a
complete stop. The temperature gauge never went
high but I can’t stop it from doing it

1 Answer

Temperature gauge might be giving you a false low reading. Also be sure you are running a 50/50 antifreeze mix, radiator cap is okay, radiator fans coming on at the right time. I want to guess the fans don't come on...check fan motor, fuse, relay, sensor.
