[QUOTE="ThxOne, post: 8686779, member: 675210"] P0128 Coolant temperature below threshold. 3.5L 2008 G6 GT. Automatic Trans. (ECT) Engine Coolant Temp sensor. Located below the throttle body in the head. 3/4" box wrench/short handle works best. Simple replacement. Clear the code manually. If the code comes back, change the thermostat. Remove passenger headlight to gain easier access. 10mm bolts on thermostat housing. Clear code manually. DONE! Pontiac, Chevy, GM in general. On the Pontiac the most often culprit is the thermostat for the P0128 code. [/QUOTE]
