How do I remove the oil pan on my 2007 Chevrolet Uplander?
I've had this problem on mine. Found out the reason was because there's four bolts on the side of the pan two on each to be exact and their 13mm nuts same as the ones around the oil pan once those are removed your pan would drop easily. Be safe, wear safety goggles ?? and good luck
How to remove the headrests from the driver and
Remove the storage tray from the back of the driver and passenger seats.
This can be a trick in itself. You have to squeeze together some body
style clips with needle nose pliers going in from the bottom where the
tray section meets the seat fabric. When you get the right and left hand
side clips free the tray panel should just tilt out at bottom. Then
just slide the whole tray panel up and then you can pull it out. Now you
can get to the head rests. From the inside of the seat you can see the 2
head rest posts that connect to the cushion portion of it. Follow the 2
posts up until you see the black plastic sleeves they slide in. Take
some channel locks and grab the black sleeves and turn them (they only
turn one way) until the cut outs in the bottom of the sleeves are facing
the front and rear of the van rather than the right and left sides.
Once these are turned you can easily lift the whole head rest out.
What damage can be done by the alternator over
If overcharging to much can damage the computer and burn up the battery, if the battery is a service free battery then it could boil the water out and if their is a spark it could cause the battery to explode. Most free maintenance batteries are not maintenance free, they can still have water added to them and need cleaning from time to time as the posts corrode up.
Where is the coolant temperature sensor on a 2007 chev uplander 3.9 v6 located
Drain the cooling system. Refer to Cooling System Draining and Filling . Remove the intake manifold cover, if necessary. Refer to Intake Manifold Cover Replacement . Remove the exhaust crossover pipe. Refer to Exhaust Crossover Pipe Replacement . Disconnect the engine coolant temperature (ECT) sensor electrical connector. Remove the ECT sensor.
Engine Coolant Temperature Sensor
In the left side of the front cylinder head, above the transmission
Condensate drain location
Look way up under the dash, near the end of the carpet. What you are looking for is (usually) a black hose, thicker than a vacuum line, but less than a heater hose, for example.
What happens is a passenger unknowingly kicks the hose off the heater/AC box, then it leaks out. The hose is a hand press fit.
Rarely have I found the hose plugged. If that happened, you would likely have a complaint of fluid being blown out the a/c vents.

Have the vehicle check for DTC'S - diagnostic trouble codes . Most all parts stores will do it free of charge . They will also do charging system testing .

2007 Chev Uplander 3.9 Could ECM need replaced? Where is it located?
This is not that clean cut, ECM failure is not that common. The battery died and that caused the no start. This could also account for the setting of that code because of loss of field charge in the alternator. A dealership can write off parts that are not bad, if they did not do the work, you are stuck with the parts. ECM is not cheap. I would check the CPS first.
2007 Chev Uplander 3.9 Could ECM need replaced? Where is it located?
Without testing we'd only be guessing ! You have no idea of the complexity of the electronics on your vehicle . Replacing the ECM would mean a trip back to the dealer to have it programmed . Without programming your vehicle will never start . You had new battery an alternator installed , did it start an run when you picked it up. The charging system on your vehicle is computer controlled . DTC P0621
DTC P0621 : Generator L-Terminal Circuit
The engine control module (ECM) uses the generator turn ON signal circuit to control the load of the generator on the engine. A high side driver in the ECM applies a voltage to the voltage regulator. This signals the voltage regulator to turn the field circuit ON and OFF. The ECM monitors the state of the generator turn ON signal circuit. The ECM should detect low voltage on generator turn on signal circuit when the ignition is ON and the engine is OFF, or when the charging system malfunctions. With the engine running, the ECM should detect high voltage on the generator turn on signal circuit. The ECM performs key ON and RUN tests to determine the status of the generator turn on signal circuit.
Your best bet take it back to the dealer .
