2011 GMC Acadia - Answered Questions & Fixed issues

The torque specifications for the catalytic converter on a 2011 GMC Acadia can vary depending on the specific model and engine type. However, the general torque specifications for the catalytic converter flange bolts on this vehicle are typically around 37-45 lb-ft. It's important to note that these torque specifications are for general guidance only, and you should always consult the manufacturer's service manual or a qualified mechanic to ensure that you are using the correct torque values for your specific vehicle and application. Additionally, it's important to use a torque wrench when installing or tightening the bolts on the catalytic converter to ensure that the correct torque is applied and to avoid over-tightening or under-tightening, which can lead to issues such as exhaust leaks or damage to the exhaust system.

My Acadia would die while I was pumping gas and then it would take multiple attempts before it would start after filling with fuel. I changed the purge valve solenoid and haven't had issues since. A new solenoid cost me $60 at autozone

Always start in the center and spiral out is always accepted and works just fine

your on the right track! your blend door is broken or your blend door actuator is broken.

Or a rely or blocked jets

Yes the fuel tank has to come out to change the fuel pump. But are you sure that is the problem ? Your vehicle has a Fuel Pump Flow Control Module (electronic's ) Or is it just your fuel level sensor you want to replace ? And to your question of if the fuel level sensor is bad will the car shut down if the gage says it is emty but it is not? No ,this will not shut down the vehicle. You probably have no idea of the complexity of the electronic's involved an the thing's that can cause the gauge not to work . Fuel Gage The instrument panel cluster (IPC) displays the fuel level as determined by the ECM. The IPC receives a serial data message from the ECM indicating the fuel level percent. The fuel gage defaults to empty if: • The ECM detects a malfunction in the fuel level sensor circuit. • The IPC detects a loss of serial data communications with the BCM • The BCM detects a loss of serial data communications with the ECM When the fuel level is less than a pre-determined value, the low fuel indicator illuminates in the IPC. Unless you have a factory or professional type scan tool your better off taking your vehicle to a qualified repair shop. Fuel Gage Inaccurate or Inoperative Circuit/System Description The fuel level sender changes resistance based on the fuel level. The engine control module (ECM) monitors the signal circuit of the fuel level sender to determine fuel level. When the fuel tank is full, the sender resistance is low and the ECM senses a low signal voltage. When the fuel tank is empty, the sender resistance is high and the ECM senses a high signal voltage. The ECM uses the signal circuit of the fuel level sender in order to calculate the remaining fuel level percent in the tank. The ECM sends the fuel level message via the serial data circuit to the body control module (BCM). The BCM sends the fuel level percent to the instrument panel cluster (IPC) via the serial data circuit for display on the fuel gage.

You might have a bad actuator ?

Which seal is leaking?

If the master switch will open and close the windows and the rear switches open them, won't close them, replace both rear switches.

Look straight down by the oil filter in the front. It is next to the oil filter. There are two alum pipes coming directly off the compressor.

The front motor mount and the upper engine strut mount both commonly fail. Start engine and have someone rev engine and let off while you look to see if either mount is moving excessively. The noise you are describing it is likely either or both the mounts.

should a tenant have to tolerate a putrid odour from an outside vent caused by natural gas?

JUST A NOTE til U get your answer. Some of these GM vehicle has an electric power steering pump, to be Factory service and check only. Check owners manuals.

It does not inflate. It uses an electric motor that pulls a spring together. You need to remove the seat back and check it for power and ground signal but it is most likely broken and needs replaced...

Not prewired. Will require wiring, relay, and bcm programming for control.

If the steering wheel moves back and forth at 15-20MPH, the tires most likely have a slipped belt. The only way to diagnose which one is bad is to get a full size spare and put it in place of one front wheel, drive it and see if the problem is still there. If it is, put the wheel back on and the spare on the opposite side and drive it again. If you need further help, reach me via phone at https://www.6ya.com/expert/forrest_f5a3e9d21691ce99

You should get your engine's cooling system diagnosed. A cooling system pressure test and engine block test may be in order to correctly assess the situation. The engine in your vehicle is commonly known to have leaking water pump issues. If the engine has overheated multiple times, you may also need engine repairs (blown head gaskets) that can be diagnosed with an engine block test.

Bumper to bumper warranty? You having problems or just want a diagram?

You might just have a wire loose somewhere. My 96 Cadi did that a couple of times lastyear, then it was fine. Hasn't done it since.` So, who knows! Sorry, not much help to you.

just like the armstrong siddleys from when i was a kid ,they had a freewheel device which was mechanical but this is electronic controlled and without a circuit of the computer ECU i couldnt say but somewhere their is a sensor that is reading the RPM and if i knew what it was and how then overide it ,ask dealer if they can do it for you
