Having problems with your 1998 Pontiac Bonneville ?
I have a 1998 pontiac bonneville it over heats cause the fans want come on but when i unplug the coolant temp sensor they run all the time
Replace the coolant sensor,and bleed the air out of the cooling system.Sense you are in there,it would be a good idea to replace the thermostat.If this was at all helpful,please rate,thank you.
