the thermostat is too the front of the engine,, close to the exhaust system however i dont think thats your problem.. I'm thinking a broken cylinder head gasket.. causing the radiator to pour off into the engine..

try this.. fill the radiatior with WATER,, leave cap off,, start the vehicle,, if you see water pumping back out the radiator then you have a gasket issue (cylinder head gasket).. if not,, driver around for a while with the cap off ,, if the water remains the same height then more than likely one of the radiator hoses has a micro fracture ,, this will cause the coolant to evaporate and escape in the form of steam ,, basically vanish without a trace.

let me know what happens.. maybe another expert here will have another idea.. I'll post it out in the main forum and seek assistance for you,, BTW dont post your personal info on the net like that,, its kinda dangerous..

The chattering sounds like some thing loose,like a mounting bracket. or the shafts end play is excessive,there can be bearing failure at high mileage in the supercharger, The bearings are lubed by the engine oil while running check for oil leaks in the line to the supercharger.

The usual problem here is that the Power Steering pump driveshaft seal is what fails so you have Power Steering fluid leaking out there. The easiest solution is to replace the Power Steering pump with a re-built one, but in my case I have already taken the pump off, and removed the pulley from it because my plan is to just replace the pump driveshaft seal since I know that the pump itself is fine because it worked perfectly prior to the leaking problem, and I am incredibly cheap. Because replacing only the driveshaft seal requires a higher level of skill, this may not be for the average do-it-youselfer so in that case replacing the entire pump would definitely be much easier but you'll probably still have to remove the pulley from the old pump, and then re-install it on the replacement pump.

A puller is required to remove the pulley, and a simple installation tool will put it on the new pump! This is really not that difficult if you have these tools, which can be rented for a few dollars at some large auto parts stores. A little experience is also helpful. To me, this is not really that difficult a job, but then I've been doing my own work on cars since I was about 15, which is about 30 years. Be sure to clean everything so as to remove all Power Steering fluid from all pulleys and belts, and also be sure use the appropriate new Power Steering fluid for this vehicle when filling the reservoir to the proper cold level, and do not over-tighten belts.

Hope helps.

Hi, Congrats on owning one of the fastest production car engines in the world. The way you want to do this is - only tighten each bolt about a hand shake tight - start in the middle of the intake - tighten the one closest to you and to the center of the intake - about half or a good hand shake - tight. Then on the opposite side of the intake tighten the one directly across from you - Like the illustration above - keep going outward from the starting point - like in an oblong circle and you will be fine. Double check your torque requirements as I think 89 INCH -that's INCH pounds NOT foot pounds is all you need but - take down your vin# and call your local dealer too. He will even print out the sequence you want - for your particular vin number. Be sure to check for RECALLS while your there. Thanks for letting me serve you - please rate me 4 -- and comment good bad or indifferent. Thanks

Check all your fuses and the fuel pump relay. Your fuel pump may not be working or weak, you need 44-48PSI of fuel pressure on the 3.1 liter engine to have the fuel injectors to operate.
Once you have determined that you have fuel pressure and that your fuel system is in running order, move on to the crankshaft sensor. The crankshaft sensor sends signals to the car's ECM which will command the fuel injectors to operate at the right time for proper engine operation.
You say your getting fire so i am assuming you have your ignition system running 100% so start with checking the fuel system and then the crankshaft sensor.
Thank you for using fixya and keep me posted, be glad to help you get your car running 100% again soon.

Yes they are located in the same fuse box.

Good car you've got dear.

I need to know what all you checked that made you put a new fuel pump in and what year the vehicle is.Did you check the fuel pump fuse,pump pressure,and connections?Sometimes the connections get corroded at the rear connector by the tank.Did you check for spark at the plugs?Let me know.

It sounds like a defective temp door actuator. It is behind the glovebox. You should be able to unhook the rod from it and move it manually. Run the engine with the glove box out and move the temp control to see if the actuators move.

Remove motor from trunk and test it using jumper wires from the battery.

You can get a used one for $20 at the junk yard or a new one at the dealer for about $80.

There is not a fuel cut off switch.

Oldsmobile... | Answered on Feb 22, 2010

sounds strongly like a fuel pump. have some one go under the vehicle while you are cranking and bang the fuel tank with their fist. it may trigger it. if it does, this is 100% confirmation.

I would start at the fuse. Does the blower motor turn off when the fuse is pulled? A relay is usually used in this circuit and can sometimes "stick" allowing the blower motor to receive constant power. A quick check to see if it is a wiring problem, switch or the relay its self would be to find the blower fan relay and see if there is another one of the value you can swap with it. If the problem goes away, chances are it is the relay but I always like to take a volt/ amp reading to double check my work.

on the right side of steering colum there is a plug. there is a wire that gets warm and loses connection. check by moving plug. my heater and ac would not work and caused the vacume swith to stay open.

There is a fuse at the passenger side footboard that has blown. Sitting in the seat, your toes point to the panel that needs to be removed (bottom of glove box facing down). There should be a 15a fuse in there that has blown. Replace it last. First you need to find the short behind the radio and a/c control panel. Sometimes they are difficult to find but look carefully around areas where the wire harness has been near a sharp corner or surface. You should find it in there. If not, the short is located in the main harness near the fuse panel. I wouldn't advise going in there, you should just take it to an automotive electrical specialist if you cannot find it because you will pull your own hair out trying to find it and it really isn't something that I can easily tell you how to do. Those starting points should help you out though and Good Luck!

There is a fuse and or a relay you need to be looking for. Also for the fuse to be blown something has had to have shorted out. It could have been water causing the short or you have a bad wire somewhere grounding out.

might be behind the glove box or under hood on firewall
