    can't see the solution, where is it????

    My engine light stays on most of the time but the coolant light pops on about every 5 days because the anti-freeze has evaporated. I replaced the radiator and still have the problem. The car does not run hot.

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.

2008 f350 6.4 liter wrench light on reduced engine power on no codes water pump and housing replaced thermostats replaced coolant flushed twice oil coolers free flowing lights are still on any sugesti


Have the codes read. I haven't worked on any thing to date that reduce power because of the coolant system or the oil. I have done some that will kill the engine because of both, but not reduced power. This could be from an engine hard part, sensor or wiring. Most times it's caused from a transmission problem.

High coolant level


thermostat probably sticking.
Autoparts store will scan the computer for you for free.
They will give you the trouble code/s that make the check engine light come on.
You can just google the number they give you if they don't tell you what it is/means.
Should look like P0130 or P1429 and could be more than one trouble code.
The repair should be easy once you have the code because it will tell you what the problem is.

Trouble codes p0118 temperature po118


code p0118 refers to engine coolant temperature (ETC) sensor ---circuit malfunction===causes---coolant thermostat---wiring open circuit/short to positive---wiring short to ground---ground wire defective---ECT sensor.. The temp gauge works off a temperature sender unit separate to the coolant sensor and if it is reading 100 then it indicates an overheat situation in the engine . Probably why the engine light is coming on. As the thermostat is in the list of causes I would replace it as a precaution. The coolant sensor is what tells the CPU to turn on the electric fans to cool the radiator

1998 grand prix low coolant light keeps coming on thermostat,hoses,radaitor,and intake gaskits have been replaced...the radaitor is full everytime i check it


If the engine is running well and not running hot, chances are that the coolant level sensor has failed. You can either replace it or ignore the warning light and just check the level as "routine maintenance"
while checking your oil and other fluids weekly as every good vehicle owner does and has done since there were cars to drive.

How do I replace the thermostat on my 2000 Buick Lesabre Limited 3.8 liter V6?


find where the upper radiator hose goes into the engine. the thermostat lives under that cover. drain some coolant from your COLD engine(to avoid burns) remove the bolts and replace the thermostat. be sure to also purchase a new gasket. some 3.8 s use both a rubber and paper gasket. parts store should have listings. reinstall, refill coolant, and run engine, topping off coolant as engine warms. some have small bleeder screw on the thermostat housing to air in bleeding air while filling. just crack it open until steady steam of coolant comes out. test drive and recheck coolant level. recheck coolant and adjust level for the first few days.

My water light was coming on and after I turned the car off would go off but would come back on during driving would that mean the radiator cap may be needs replacing. Because when I checked it everytime...


Yes It could be the problem due to the proper seal against the seal on the cap. If the heating system is fine and well it shouldn't be the thermostat...................But the proper flow through the engine may effect the temperature sensor for the fan.................Hope this helps.

If you can go to Autozone they will scan the codes for free and let you know what the problem is :) Without knowing what the code is this could be a lot of things.
