2006 GMC Envoy Denali - Page 3 - Answered Questions & Fixed issues

Google search GM 5.3 oil consumption. This is a known and common issue. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Air in cooling system? Blockage? Thermostat failing? Collapsed hoses. there are many reasons why this problem exists. Hot coolant passes through your heater core which is generally located on the firewall of the car. If hot coolant does not circulate into the heater core, it will not pick up the heat and your car heating system will blow cool air. Coolant circulation is most likely the underlying issue. Your water pump may also be failing.

May something wrong with the airbag. You can have a try of airbag reset tool. inexpensive and easy to use.

Check fuse #13 in the underhood fuse panel.

V8? in back of engine, on top, at firewall, its tough.

Give me some more information about this problem. May be i can help.

{: ) There are several possible causes and a scan tool is the best way to pinpoint the cause. However, you can check your throttle body for carbon build up. If it is, it must be cleaned. Clean the air filter as well. When done, an idle learn procedure will be required to reset the throttle.

Here is the instruction manual shouldn't be hard to find, usually it is under the hood.

just had oil pump installed and still have no pressure

I am having the same problem and the dealer says they checked for an "over-active lifter" - no luck, checked for leaks (there are none!) and checked the plugs, all of which seemed to be darker than they should be. They said the GMC factory rep told them to squirt some clearner in the combustion chamber which will clean out the carbon built-up around the rings. We are to drive the car for 1,000 miles and check to see if the oil level is down. Personally, it sounds like a lot of BS to me!

YOU WILL NEED TO RE PROGRAM THE UNIT WITH YOUR DOOR OPENER.

HOPE THIS HELPS

you need to get your ac serviced and computer checked for an air conditioning system code/malfunction. when the light in the button flashes it means a problem has set a code in your body control module that controls the ac.

they are bolted in a not to hard to remove once the air is drained from them however you can not drive it without the air bags. It will bounce way to much to control the truck.

Cleaning the throttle body is certainly the right thing to try first. Make sure you clean the throttle plate as well.

Classic signs of idle air control not able to cope with sudden engine loads. Cleaning should resolve this. Remove ducting from air cleaner to throttle entrance. Spray with carb. choke cleaner or WD40 spray and wipe back to the alloy finish. clean the the throttle plate and push the throttle open with your fingers and clean in behind as best you can. Clean the passageways to the idle air control valve. Remove the valve and give it a thorough clean up. Reassemble and it should all be good.

Depends on what needs to be done. For prices that blow dealers out of the water go to arnott.com or suncoreindustires.com

Oil Pressure Test Check for proper oil pressure at the sending unit passage with an externally mounted mechanical oil pressure gauge. A tachometer may also be needed, as some specifications may require running the engine at a specific RPM.

1. While the engine is cold, locate and remove the oil pressure sending unit.
2. Following the manufacturer's instructions, connect a mechanical oil pressure gauge and, if necessary, a tachometer to the engine.
3. Start the engine and allow it to idle.
4. Note and record the oil pressure reading when the engine is cold. The engine may need to run at a specified RPM, if so check the vehicle's specification.
5. Run the engine until normal operating temperature is reached.
6. Check the oil pressure reading again with the engine hot and record the value. Turn off the engine.

Compare the hot oil pressure reading to the specification. If the reading is low, check the cold pressure reading against the specification. If the cold pressure is well above the specification, and the hot reading was lower than the specification, the engine may have the wrong viscosity oil. Change the oil, making sure to use the proper grade and quantity, and then repeat the test.
Low oil pressure readings could be attributed to internal component wear, pump related problems, a low oil level, or oil viscosity that is too low. High oil pressure readings could be caused by an overfilled crankcase, too high of an oil viscosity or a faulty pressure relief valve.

give me your adress where i can send it to you.

If your sure that the tires are balanced and that all the suspension componets are good then it is time to start looking at the drive train.

The problem will be either an unbalanced drive shaft due to a weight falling off or a bad U joint.

Thanks for using FixYa.

gently raise up the wiper arms and look directly in the middle section of the arm where the blades are seated. You will see a push in clip that has to be pushed inward to relase the wiper blade. While pushing the clip inward hold in in p;ace and wiggle it loose. Then you can move the wiper blade somewhat to remove it. It isn't the asiest thing to change and it is very hard to explain also. Showing you you be alot easier for me but going by these instructions it should come off for you. Installing is not that difficult. Taking them off is the hard part I know
