Make sure the radiator is full of coolant. When the engine is cold from sitting several hours open the radiator cap (if you can). It should be 100% full. If not it has a leaks somewhere.

How to replace blower on a2004 bonneville

Pretty typical for our generation of Bonneville (mine's a 2005 GXP). There are at least two different fans for our generation of Bonneville.
Remove the panel under the passenger side dash; I recall two small screws.
There may be a couple wires to unplug from this panel.
The blower motor is located right above the passenger toes.
Unplug the three wire plug.
Remove a small rubber hose. It has one right angle bend. It's about the size and length of a big thumb.
Remove 3 small screws on the fan, and the fan comes out.
Here's my new one: zeevert_33.jpg The Hole under the passenger dash. Insert blower here: zeevert_34.jpg

I have a 05 bonny gxp and am wondering where my blower motor is located at?

I have a 2005 Bonny GXP and have replaced the blower motor.
It is located under the dash, passenger side, just above the passenger toes.
It's easy to replace, and the cost of the blower has come down a lot!
I did a write-up with pictures at:
You may have to register (for free).

Basically, remove the kick panel under the dash. Unplug the blower. Remove the vent hose. remove the three screws holding the fan, and it will drop out.zeevert.jpgzeevert_0.jpg

How to replace the battery on a 2004 Pontiac Bonneville?

I have a 2005 Bonneville GXP. I would expect yours to be the same as mine.
My battery is located under the rear seat.
Pull the fron of the seat straight up. There are two clips holding it.
Underneath you'll see the battery and a fuse block.
The cable and holddown clamp is pretty obvious.
Make sure you get the right size battery.
Also loosen the ground strap and inspect for corrosion and retighten.zeevert_1.jpgzeevert_2.jpg

Oil pressure guage dropped to 5 after an oil change in my pontiac bonneville gxp 2005

Did it stay there? If so, put a pressure gauge on the engine, to check the actual pressure and then you will be able to tell if it is just the sending unit/pressure sw , that is off.

I don't have a problem for say but looking for some feedback. I'm looking at buying a 2004 - 2005 Bonneville GXP with the Northstar 4.6 Engine. A co-worker who's a mechanic heard me telling someone and...

If it has the northstar, skip it or get a good warranty with it. They are expensive when they break, and it usually starts having problems around 70K.
