Screw/Valve Bleeder

Screw/Valve Bleeder
I am having a couple of issues with my 2009 LT but lets start with the water sound coming from behind the dash issue. I was told it is air in the line and I need to burp, purge, bleed the air out. I have no idea where to locate the bleeder valve/screw to do this. If someone could please let me know exactly on this picture where to find them that would be awesome.
On a side note I'm heading over to a family members to have the code reader hooked and find out why I get the engine light/stabilitrak/reduced engine power warning coming on and off.
Thanks

Disconnect the EGR valve harness and remove the engine cover. You will then see the bleeder screw atop the water pump housing near the EGR valve. Per the service manual, the front right corner of the vehicle must be jacked up to properly bleed the cooling system with the bleeder screw.
I don't care what anyone says, I believe that sloshing sound you hear when you first start the engine is normal. I've been hearing it for years, and it is only audible when everything is turned off. Everything else works & sounds fine. The heater works great, and the engine never overheats or runs hot so I don't worry about it. You can bleed it with the bleeder screw until your heart's content, but I'm convinced that you will never get all the air out unless you have a power/vacuum bleeder like a shop uses.
Regarding your other issue, post what codes you find here.

Thanks Ruley, I will probably just leave it for now. It doesn't overheat and my heater works fine. The other issue is much more of a concern. I will post codes.
Thanks again

I just noticed in your last post that you also said you were seeing the "Reduced Engine Power"message. I bet P2135 is the code you find. If so, you'll need to replace the TPS on the throttle body. It's a common issue with the 3.4L/3.5L/3.9L V6 engines. Luckily, the OEM part (p/n 19300180) is relatively cheap and easy to replace. It's only ~$55 from rockauto.com. Only use the AC Delco part, which happens to be the cheapest option in this case.

So my family member comes over with his code reader. Roadi RDT55 OBD2. Hooks it up and it doesn't show any codes. The engine light is on while doing this. Any ideas? Is it possible to update the reader? If it is I can't find out where.
Thanks

As far as I can tell, that scanner is made to work specifically with VW/Audi vehicles. It may not be able to communicate with your Equinox because of this.

I finally got this hooked up to a code reader that worked and it gave me P2135 which looks like exactly what you said. Throttle Position Sensor. Is there anything else I need to know or should I just get that fixed?
Thanks
Thanks
