I have a 2006 Buick Lucerne V6 code po128 comes up. What does it mean?


P0128 BUICK P0128 BUICK - Engine Coolant Temperature Below Thermostat Regulating Temperature Repair Importance Level: 3/3 Repair Difficulty Level: 2/3 help.jpg Share facebook.png twitter.png linkedin.png google-plus.png sep.png print.png pdf.png share.jpg 3 comments.png ' Add Comment xicon.jpg http://www.autocodes.com/p0128_buick.html Forum Code Possible causes - Leaking or stuck open thermostat
- Low engine coolant level
- Insufficient warm up time
- Faulty engine coolant temperature sensor
- Engine coolant temperature sensor harness is open or shorted
- Engine coolant temperature sensor circuit poor electrical connection
help.jpg What does this mean? Tech notes If cooling system is not leaking and the fluid level is OK, replacing the thermostat usually takes care of the problem.
help.jpg What does this mean? When is the code detected? If the Powertrain Control Module (PCM) detects the calibrated amount of air flow and engine run time have been met, and the Engine Coolant Temperature (ECT) has not met the minimum thermostat regulating temperature, the code P0128 will set. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P0128 Buick Description An Engine Coolant Temperature (ECT) sensor monitors the temperature of the coolant. This input is used by the Powertrain Control Module (PCM) for engine control and as an enabling criteria for some diagnosis. The air flow coming into the engine is accumulated and used to determine if the vehicle has been driven within the conditions that would allow the engine coolant to heat up normally to the thermostat regulating temperature. If the coolant temperature does not increase normally or does not reach the regulating temperature of the thermostat, the diagnostic that use ECT as enabling criteria may not run when expected.

Regarding which thermostat to use, I am guessing it depends on where you live.

Ask these people when you order the thermostat.

How do I change the thermostat on a 2006 Buick lucerne?


follow the top radiator hose to the engine , the thermostat will be housed in a casing that the top hose joins to , the housing will have 2-3 bolts that need to be removed to gain acces to the thermostat, when fitting new thermostat ensure it is fitted the correct way round , take a picture of the old one before removal then you can't go wrong , ensure you have a new gasket to fit as well and make sure the two faces of the housing are completely clean of the old gasket material as otherwise you will get a leak , hope this helps

Where is the thermostat in the 2007 Buick?


It should be on top of engine where the top rad hose enters the engine. The hose goes into the thermostat Mine is held on with two bolts and is very easy to change . Do not over tighten the bolts or they could break off. I did that once and make sure the new thermostat is installed right side up. If your hoses have not been changed for a few years they should be changed when you have it apart. Save head aches later.
