What tools are needed to change the brake pads on a 1994 Pontiac Bonneville?

Generally for any car you will need your jack and tire iron, you will probably also need a 10mm open end wrench or socket, I can't remember the name of the other tool commonly needed, a star bit is what I have known them as, it may be needed, a large one. You may want to use a flat head screwdriver to pop off the old pads, and will need a c-clamp. The c-clamp is used with one of the old pads to push the brake cylinder(s) back to the down position. That should be all the tools you need, I have never worked on a Bonneville but this seems to be the make-up of Pontiacs. I hope I have been of some help

Just did front brakes on a 94 Bonneville. You NEED a 3/8 Allen/socket...They are hard to find but a regular Allen wrench is NOT long enough. These fit on a 3/8 socket wrench and it is HARD to brake them. Drivers side goes up. I just replaced the caliper on this car. This will be the only time you use this socket for sure.

How much does an average car weigh?

Average U.S. Car Is Tipping Scales at 4,000 Pounds

The E.P.A.'s weight statistics show that the average weight of a 2003 car or light-duty truck, like a pickup, sport utility, van or minivan, was heavier than in any model year since 1976, when the average peaked at 4,079 pounds. Just five years later, after the oil shocks of the 1970's, the average had fallen by more than 20 percent, to 3,202 pounds. The figures take into account the sales volumes of different models.

Average fuel economy peaked at 22.1 miles to the gallon in the late 1980's, according to the agency, but has eroded since then to 20.7 miles for the 2003 model year.

The agency expects the 2004 model year to finish with an average weight of 4,066 pounds.

My 2001 Nissan Altima weighs 2945 pounds. I believe it is an average sized car. My Ford Cargo Van weighs 5271 pounds, for comparison.

How do you remove positive battery cable from ac delco professional battery under rear Cadillac seat?

I am not familiar with your Cadillac, so this answer will be generic in nature and the procedure is about the same for all vehicles. First, understand that the negative cable is grounded to the metal frame and body of the vehicle. Therefore, IF you accidently touch a wrench, pliars, or any electrically conducting metal between the positive battery terminal or connector while the negative cable is attached, there will be a major electrical arc [monster spark(s)] which could injure you or cause the battery to explode, damage the wiring and/or onboard electronics, or possibly cause a fire. Therefore, DO NOT mess with or allow any contact with the positive terminal UNTIL the NEGATIVE TERMINAL CLAMP/CABLE has been disconncted first. To disconnect the negative terminal you will need a couple of wrenches, one to hold the clamp bolt while you loosen the clamp nut with the other. You do not have to remove the nut or the bolt, only loosen it well. To remove the negative cable clamp you twist and lift it. This can sometimes be done with your hands, but if it is too tight, there are battery clamp removal tools availble at almost any auto parts supply store. Sometimes they even loan tools. Once the negative cable/clamp it totally removed away from the negative terminal of the battery, you should use an old piece of string to tie it back so it cannot accidently come into contact with the negative terminal until you are ready to reconnect it. Then using the same procedure, remove the cable/clamp from the positive terminal, being careful not to allow any metal [wrenches, pliars, etc. to come into the negative and positive terminals at the same time. To reconnect the battery, just reverse these instructions.

Water Pumps

How do you replace the water pump on a 1995 Pontiac Bonneville?

I just replaced the water pump on my 1996 Bonneville with the 3800 engine. I'm not real experienced with working under the hood, but I managed to get it done in an hour or so with little trouble. You'll need a socket/ratchet set with an extension, some open-ended box wrenches, and it might help to have a special compound to put on the gasket of the new pump when you put it on. I can't offer a full list of steps in order (this was my first time and I had some help), but here are some tips to keep in mind:

-Make sure you have a clear diagram of the serpentine belt before you take it off. Your Bonneville user's manual (if you have one) should have it in there, otherwise you can draw a picture of it yourself before you remove it, or better yet, check a Chilton or Haynes manual at the library. This is important.

-On mine I also had to remove the starter to get at one of the bolts on the water pump.

-Once the old pump comes off, be ready for some water/fluid to drain out.

-Unless your model is different from mine, you shouldn't even need to get under the vehicle for the replacement.

-The pump I bought was $40; you might even find one for less.

-It may help to have an extra set of hands to put the belt back on at the end. By the way, this would be a good time to replace your belt if it needs it.

-You'll want to flush your coolant system once the replacement is done.

Why does your ac unit continuously run when in auto?

It could possibly be because the fan relay is stuck in the closed position, even though your thermostat is not demanding a cooler temperature. This could be caused by the copmressor icing up for a long period of time causing the contacts to weld themselves together. This is only a possibility - hope it helps!

Where is the heater core in a 1992 Pontiac Bonneville?

It's buried underneath the dash, and, the question you ask is too involved for a proper answer. You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

Where is the heater core in a 1992 Pontiac Bonneville and how do you access it?

Best thing to do is to put your car up on ramps and crawl underneath it and trace where the heater core lines got to in the fire wall. Some heater cores are located in the engine compartment and some oare located inside the vehicle under the dash. Most common places for them in cars is under the dash either on the passenger side behind the glove box or right in the center under the radio. If it is in the center more than likely you will have to remove the dashboard to get it out. If it is in the center and dash removal is necessary it is like a 14 hr labor job in a garage and that can be expensive or a 23 dollar part. Keith(JcWhitney Tech Dept) www.JCW.com

How do you troubleshoot a problem with heated seats on a 2000 Bonneville?

Check your fuses first. Then test for power (voltage) with the switch for the seats on. Use a multimeter or test light and test both sides of the switch and where it goes into the seat as well.

I too have the same problem on a 2000 bonneville, drivers seat, I am able to turn the switch on and then it cycles off within a few seconds. I have checked the fuse and it is fine. #16 and #31 on the 2000 ssei.... let me know if you find the answer

I have the same problem. I have replaced the switch and the controller. same problem My element shows a good resistance. I think there is a thermostat in the seat pad that is the problem. I can see a return line from the elements. Ill let you know if it is that Jim

Why does the CD player register E20 and spit the CD out on a 1998 Pontiac Sunfire?

E20 is a focusing error. You have take the CD player apart and clean the lenses. Can also be caused by high heat and/or humidity. Try also re-seating the multi-conductor cable going between the CD player the the upper circuit board.

AnswerIt could also be caused by, the anti-theft system. If the anti theft system has been set on the stereo, and the deck has been removed and re-installed, the system will not work. but by the sounds of it! its most likely because of the reason the other guy said. But consult your Sunfire's driver guidebook for more information on the anti-theft system. AnswerThis error is a problem with the focus on the CD reader.

If the error only occurs on certain CD's then it's most likely a problem with a smudge or scratch on that CD and not the lens itself, but if it is occurring on all CD's then it's time to either clean the lens or replace the unit.

The only way I've found to reliably fix it is to remove the CD player and clean the lens with denatured alcohol manually. Over the counter CD cleaning kits do not seem to have any effect on the error.

AnswerIn my car it only says that when I play CD-Rs :\

How can you repair the power door locks on a 1988 Pontiac Bonneville if they are stuck and you can't unlock three doors?

On the fuse panel you should have a circuit breaker for the door locks. Remove it and see if it will let you unlock the doors.

I can't really give you an answer, but I have a similar problem with a 1989 Bonneville and have discovered that there's a second fusebox (besides the one that's easy to get to under the steering wheel) that's on the passenger side under the glove box. I've taken off the 'sound control panel' at the bottom of the door and unbolted this other plastic panel under the glovebox.

The panel could then be pulled down enough to reveal a sticker with the fuses listed.

These cars typically suffer from this. It is not usually caused by the power locks, if you can hear the lock mechanism clicking when you press the button, it is most likely fine. The root of the problem is that GM started to use a vegatable oil based lubricant on the lock mechanism around this time to replace the previously used whale oil based lubricant. Over time, with lack of use, this dries into a sticky residue and does not allow the lock to disengage. Usually only the driver's door will still work, since it gets the most use. If you push in the lock button on the exterior of the door and it feels like there is "nothing" behind it, this is likely your problem. To simply get your doors open try this: Have someone click the power lock open and closed in rapid succesion while you hit (hard) with the side of your fist on the top of the door handle (exterior of car) several times. Make sure they stop clicking the lock with it in the open position, then try the door, this will often free the stuck lock. The only real cure for this is to remove the door panel and lock, then clean and relubricate the lock. Another tip is NEVER push in the exterior door button when the car is locked, it will just about guarentee that the lock will stick.

FYI - May 2010 - I followed the above procedure on my 1989 Bonneville that had two doors stuck locked and the battery would run down when the car was parked. It took my grandson (on the outside banging on the handle) and me about 45 minutes to unlock both passenger side doors. And the battery no longer discharges while parked!

How do you change the ignition switch on a 1989 Pontiac Bonneville?

You have to remove the steering wheel, horn and turn signal assemblies. Make sure your wheels are straight before you remove the steering wheel. Remember the proper order of parts for re-assembly and get the GM steering wheel compressor tool as well as a good steering wheel puller. The switch requires the key in it to remove. There is a spring loaded catch at the rear of the cylinder that locks it into place. Once this is depressed, it will just pop out. Make sure the battery is dis-connected before beginning and if the compressor tool isn't available, get a buddy with a good set of shoulders to hold the wheel down while you place the main nut. A little tricky if you haven't done one before.

Where is the moonroof motor on a '96 Bonneville and how hard is it to replace?

The motor for the sunroof will be on the back side of the roof. The only way of getting to this is by dropping the headliner out of the car. Once you have the headliner out, there will be two screws or bolts that holds the motor in. remove the two screws and the motor should drop down,then just unplug your wires and you will be able to replace it then.... GOOD LUCK.

Is there a special oil for the Supercharger in a 91' Pontiac Bonneville SSE and how do you put it in?

I have 2 1992 Bonnevilles that were leaking the supercharger oil out in short order. The replacement seal is a DAE 20x47x70 MM. GM replacement oil is part #12345982. The service manual at the GM dealer says a synthetic oil is OK. Any machanic should be able to replace the seal and refill with oil. The fill cap screw is under the plastic shield and is torx. The pulley must be removed with a small gear puller. Hold the pulley with a link wrench or pipe wrench to remove the nut and replace. An air impack is a total NO,NO. Can cause internal damage. (Fairly tight, DO NOT POUND ON ANY PARTS as this may cause internal damage).Clean up any marks on the pulley with a fine file after you are finished and replace the belt."Below has not been added by me, You will not find any info in your owner's manual, Only in a Service manual ". 50+ years machanical, Head Mechanic at a 320 boat marina, Life time of Electronics, 20 Years Now electronics Business.

This information can be found in your owner's manual. If you do not have one, then I suggest you get one. You need an owner's manual to know what items to service and when, and for specifications. You can order one from a dealer, find one at a salvage yard, eBay, or one of these sites:

Where is the fuel filter located on a 1993 Pontiac Bonneville?

On a 1991 model it is located just inside the frame barely in front of one of the rear tires. I believe it is the driver's side. The fuel filter on my 1993 Bonneville is located under the passenger side floor board. It is held in place by a metal strap with one bolt. Both inlet and outlet lines are quick clip style. There is a special tool to release these clips, but I have always managed to get it done with a pair of needle nose pliers. Be ware, with the front on ramps the only way to get to it is behind the right front wheel, and the possibility of fuel leaking on you is great... be careful.
