heater core is leaking

these cars use a side post battery and on the positive terminal there are two leads, one goes to the starter and the other powers everything else in your car, corrosion builds up between these contacts and you loose all cranking power,90% of the time its just a bad connection , it takes a 5/16 wrench or socket to remove the terminal, simply clean with hot water and put back together you should have cranking

it is located usually near the right side rear along the frame rail near the pass side tire and yes there is a special tool that you can rent from autozone to remove the lines

32lbs/sq. inch assuming you have the same normal tires that come on your Buick. It should also be marked on the tire & the driver's door label. Hope this helps. Good luck!

Depends if there is rear disc brakes, if so the emergency is self adjusting, if there is drum brakes you can adjust the emerg buy the adjuster cable that runs between both rear wheels.

Hi and welcome to FixYa!
As a first course of action I strongly suggest that you disconnect the positive battery connector and let it sit for atleast 5mins. then reconnect it again. Start the car and observe how it goes, this should reset the system after the battery removal.

If the problem still persists I strongly suggest that you take the car in and have it scanned to know the fault code and the fix.

Hope this helps and thank you for using FixYa! Have a good one!

is this the lever type remote you are talking about?..like inside the car?..if that is the case..it would be a cable..perhaps it needs some lube (wd40) or similar

Hello, Open the hood on the passenger side just below the windshield you should see a door about 10 inches long and about 5 inches high remove it and you will see the filter.

It's pretty easy to fix.
1. Remove "wood" trim from below module.
2. Remove 2 screws from tabs at sides of module
3. Remove module (may neeed to pry a little, it's tight.) and connector plug.
4. Remove 2 screws and seperate halves of module
5. Unplug harness to from circuit board (pull the plug, not the wires)
6. Pull the 2 plastic tabs at back of box to remove circuit board, which will now slide out.
7. Inspect the board. On mine, 4 tan components with a single lead coming out each end had cold (gray in color) solder joints. I simply resoldered the joints, reassembled and it's perfect.
8 ***NOTE After reinstalling, start the car and run for a full minute before touching any buttons...this somehow sychronizes the module.

Enjoy!

Check your coolant level, these engines 3800 II has issues with leaking coolant into the engine smothering the spark plugs under hard stops and or acceleration. Only removing the Throttle body and looking inside and seeing "wet" will indicate and issue aside from loosing coolant.

If your coolant is ok look into getting new spark plug wires and plugs as well a new air filter if needed.

Also run fuel injector cleaner.

Are you getting any waring lights?

Auto Zone checks them for free.

I hope this helps.

If the OEM one is no good I would take a gander over on ebay and see if someone sells an aftermarket unit which you can buy and bolt on yourself. If not you can cheaply buy a used but as yet unfogged one, bolt it on and just wait for the fog to slowly return.

The flat rate guides do not provide labor times for replacing wiring harnesses. You are basically at the mercy of the technician who is responsible for the job. I searched Alldata, Mitchell and Mitchell's collision repair labor guides to find your answer, and none of them publish a labor guide for any wiring harnesses. Sorry.

If it runs fine when it is unplugged then what you can try before replacing the MAF sensor try cleaning it.They make a cleaner for these.I have used it and it works very well.You should be able to get this at most part stores.Hope this helps.Good luck.

Look under near fuel tank,open fuel door It may be the fuel cap try these areas and get back to me thanks

Change oil,replace spark plugs and fuel filter,air filter,check all brakes and lube caliper slides,check and flush cooling system,replace trans filter and gasket and perform a trans flush.This will replace all the trans fluid not just the fluid in the trans pan.Add fuel injector cleaner about every oil change.This will keep this vehicle going for another 100k.This is the best engine G.M. has had and will go over 300k.The biggest problem was the upper intake plenum gasket leaking coolant into the cylinders and oil system.Hope this has helped and good luck.
