2008 4.3 L alpha one
The temp alarm goes off sometimes when I am in Neutral or at low idol. Once I get up to about 5 mph the alarm shuts off. The temp gauge reads normal.
Any ideas of where to begin? If the impeller was bad I would not think the alarm would not go off at higher speeds. Maybe the thermostat?
In full disclosure I did install the battery backwards (idiot) and blew the fuse on the starter solenoid and replaced it. Could I have screwed up something else?
