Question about 2005 Pontiac Bonneville

1 Answer

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 said he's see costly problems with this engine and starter around 100K miles. What can you tell me?

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.

Why my 2005 Bonneville gxp won't get any heat?


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 do I no if i have a bad coil on my 2004 Bonneville GXP 4.6 Northstar


if you have multiple coils then there will be a regular misfire on a particular cylinder. If you have sets of coils then the coil that handles a set of plugs will misfire on those plugs. If you have one coil to do the lot then indicators are engine will not start, coil lead will show a weak orange spark when sparked to metal, engine will start fine and run for a period of time before the coil overheats and starts to break down ( misfiring), coil is very hot to the touch (burning ) after minutes of operation.

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.
