    siphon fuel from tank

    On Sunday I filled the tank on my wife's 2004 Grand Prix. On Monday somebody in a Tahoe ran a red light and slammed into her driver side fender, breaking the sub frame, totaling the car. :( The insurance adjuster will be at our house Wednesday morning and before the wrecker shows up to take our...

    interior water leak. Cowl?

    We have a 2004 Grand Prix. On a recent trip to Kansas City from Omaha we experienced a down pour. I noticed some water on the front passenger floor. My wife thought the water may have been from her umbrella. Today my wife reported a large amount of water on the passenger floor after she got...

    goofy gas gauge

    Anybody out there ever change the fuel level sensor on a '04 Grand Prix? I bought the repair kit and I'm going to take a crack at it to correct the erratic behavior of the gas gauge on our Grand Prix. I watched a You Tube video of someone doing this task on a 2001 Bonneville. It didn't seem so...

    fuel tank removal

    I have a 2004 Grand Prix with a erratic fuel gauge. I understand the sending unit for the gauge can be repaired upon the removal of the fuel pump. I know the 2003 and older models have a fuel pump access panel in the truck, so I missed out on convenience by one year. So what kind of hoops does...

    Heater Core alert

    Hi everybody and Happy Thanksgiving! This past week I installed a new heater core in my wife's 2004 Grand Prix. And while changing out a heater core on any car is not a fun or easy task, there are some unique characteristics about changing one on a 2004-2008 Grand Prix that I'd like to share...

    oil level sensor

    How often do these leak? I am finding some small oil leakage around the oil pan area on our 2004 Grand Prix and I don't think it's the oil pan. Could the plastic sensor that screws in the pan be a culprit?

    How to test heater and a/c control unit

    Okay, I think I may have pinpointed why the fan will not work on my 2004 Grand Prix. I replaced the resistor, the blower motor checks ok (I even put in another motor and it still wouldn't run), re-installed the OEM blower motor, checked the fuses again and nothing is blown there. The air...

    blower motor resistor?

    In the thick of this hot-as-hell summer, my wife's 2004 Grand Prix has had a couple of occurances where the blower doesn't operate. At times it will then on its own start running. The blower motor runs quiet and the air conditioning compressor does what it is supposed to do. I tried to get the...

    tilting a 3800

    Hi guys, I attempted to change the spark plugs on our '04 Grand Prix and stopped once I realized I couldn't pull the spark plug wires off the plugs located at the firewall side of the engine. I looked at my Haynes manual and found that I need to disconnect the battery cable, disconnect the air...

    Another weird coolant leak

    Hi guys, Yet again I have to deal with another bizzaire coolant leak on my wife's 2004 Grand Prix. The story goes like this: The coolant resevoir tank had a little leak and was leaving a puddle of anti freeze. I finally got a new tank and cleaned the inner wheel well and installed the new...

    Safety Stat

    Anybody out there ever use one of those safety thermostats? These are the type that will lock into the open position if overheating occurs. I've installed three of them in our '04 GP. I get the PO126 (PO128?) code and the culprit is a thermostat that is stuck open. I think the one I just...

    Mystery coolant leak

    Okay, I've got a dandy for you. My wife's 2004 Grand Prix has started leaving an anti freeze stain in the driveway. My first thought was the water pump. I looked all over around the water pump pulley's etc. Dry. Even the plastic tray under the compressor was clean. I noticed the over flow tank...

    rear brake leak

    Anybody ever experience a passenger side rear disc brake fluid leak on a 2004 Grand Prix? It's got to be either the brake hose or the caliper. The steel lines seem to be clean. I plan on filling the master cylinder and see if I can find where the leak is coming from when the pedal is applied...

    Water pump leak, or not?

    Hello again, A couple of months back I posted a question about a rough starting issue with our 2004 Grand Prix and I received great advice about cleaning the throttle body. It did the trick! Well I'm back again this time with a coolant leak. A couple of days ago I noticed a thin puddle of...

    3800 V6 hot start issue

    Okay, my wife's 2004 Grand Prix with the 3800 Series III V6 has developed an inconsistent hot start issue. On occassion after the car has reached operating temperature it will become hard to start. It'll stumble and quit or stumble and barely start. Eventually after cranking one or two extra...
