SOURCE: how hard is it to replace a intake gasket on a 1994 olds cutlass supreme.3.1 6 cyclinder

It is not an extremely difficult job. time consuming consuming... I've done a 3.4 intake manifold job, which in my opinion (plenty will disagree) is a little easier than a 3.1 manifold. there are just more steps involved with the 3.1 intake.(I haven't had to change the intake gasket on my 3.1 (yet)) If you haven't already, invest in a haynes or chilton manual, whip out your sockets and your gasket remover, and prepare to do battle...
oh, as far as how to tell before you break down the engine... are you having any drive ability problems? Surging idle, stalling... try this, take propane torch (DONT LIGHT IT) but open the valve and let the spray the propane around your intake manifold with the engine running. If the idle drops or the car stalls, there is your intake leak. That trick also works with intake cleaner too.

you may have to remove your push rods to put your new gasket on. Just loosen the rocker arm nuts/bolts and pivot your rocker arms out of the way. If you do remove your push rods, push them into some holes in a cardboard box so that you can replace them EXACTLY in the same position that you got them from. To remove old traces of gasket, you may have to get some spray on gasket remover, let it sit 5 min. then get at it with your scraper. (be careful, remember our engines are aluminum, you don't want to scrape too hard and scar the mating surface).  
After you get all the old gasket off, clean the mating surface with intake cleaner or lacquer thinner. your gasket kit may have come with end seals. if it did not, remember to run a line of RTV sealant on the front and rear ridges of the engine block between the heads (before you install the intake gasket.)

When you re-install your lower manifold, coat your bolts with pipe thread sealant. when you install the lower manifold, tighten the vertical bolts first, then the angle bolts- it will keep the manifold from wiggling around on the gasket.

After you get everything back together and all snug, i would buy some GM top engine cleaner (liquid)(dealer only( part# 1050002) or some sea foam from your local parts retailer. I know this is to clean the carbon and sludge from your intake and your cylinders, but guess where the remainder of the solution ends up? Yep, in your oil. That should clean up any residue you had from the milkshake effect.

To use the GM engine cleaner, just disconnect your favorite vacuum hose leading to the intake (some people just use their brake booster hose) and put it down in the bottle of liquid while the car is running. (don't let the vacuum **** the liquid too fast, you don't want to risk problems. you may have to keep your hand on the throttle to keep it running. when the can is empty, let your car stall or just cut it off. 

Let your car sit about 2 hours, to give the cleaner time to really work. Start your car, let it run for about 20 mins (there will be PLENTY of white smoke, your car is burning off the cleaner and the carbon).

Then change your oil. good luck and hope this helps.

Ok, you're going to need to buy, borrow, or rent a torque wrench. For 3.1 engines 1995 and earlier, rocker arm nuts should be torqued to 18 ft-lbs.

The wire brush probably did less damage than I do on a regular basis with a gasket scraper :D so you should be okay. If you've already drained your oil, (which I suspect you have) then I would just use the wal-mart brand while you do the GM engine cleaner thing. 
  Don't add the cleaner to your oil, just let a vacuum hose, **** it into the intake. Plenty will get in your oil. Getting into your oil and cleaning up the gook is just a fringe benefit. What the cleaner actually does is it cleans up your entire intake path (manifold, injectors, & valves)... I think you'll be happy with the throtle crispness, once you're done with the engine cleaner. 
Oh and for your coolant system, just get some Prestone radiator flush, and follow what the bottle says. If your system is really gooped up, Prestone also has a Super flush for a little extra :2cents:

SOURCE: how do I remove rear brake pads on 94 olds cutlass

Please don't forget to rate! This helps us help you!

1993–96 Vehicles

  1. Remove about 2⁄3 of the brake fluid from the reservoir with a clean syringe or baster type utensil.
  2. Raise and safely support the vehicle.
  3. Matchmark the relationship of the wheel to the axle flange. Remove the wheel and tire assembly.
  4. Reinstall two lug nuts to retain the rotor.
  5. Unfasten the bolt and washer attaching the cable support bracket to the caliper body assembly. It is not necessary to disconnect the parking brake cable from the caliper parking brake lever or disconnect the brake hose unless the caliper is to be completely removed from the vehicle. Freeing the cable support bracket allows enough flexibility in the cable to pivot the caliper up and down and remove the shoe and lining.
  6. Remove the sleeve bolt.
  7. Pivot the caliper body assembly up. Do not completely remove the caliper assembly body.
  8. Remove the outboard and inboard shoe and linings (pads) from the caliper support.
  9. Remove the two pad clips from the caliper support. To install:
  10. Bottom the piston assembly into the caliper bore. Use a suitable spanner-type tool in the piston slot to turn the piston assembly and thread it into the caliper body assembly.
  11. After bottoming the piston, lift the inner edge of the boot next to the piston assembly and press out any trapped air. The boot must lie flat. Make sure the slots in the end of the piston are positioned correctly before pivoting the caliper body assembly down over the shoe and lining in the caliper support. Use a suitable spanner-type tool in the piston slots to turn the piston as necessary. NOTE: Whenever installing new pads, install new pad clips. These should be provided in the disc pad kit.
  12. Install the two pad clips in the caliper support.
  13. Install the outboard and inboard shoe and lining in the caliper support. The wear sensor is on the outboard pad. The sensor is positioned downward at the leading edge of the rotor during forward wheel rotation. Hold the metal shoe edge against the spring end of the clips in the caliper support. Push the shoe in toward the hub, bending the spring ends slightly, and engage the shoe notches with the support abutments.
  14. Pivot the caliper body assembly down over the shoe and lining assembly. Be careful not to damage the piston boot on the inboard. Compress the sleeve boot by hand as the caliper body moves into position to prevent boot damage.
  15. After the caliper body is in position, recheck the installation of the pad clips. If necessary, use a small prytool to re-seat or center the pad clips on the support abutments.
  16. Install the sleeve bolt and tighten to 20 ft. lbs. (27 Nm).
  17. Install the cable support bracket (with the cable attached) with the bolt and washer. Tighten the bolt to 32 ft. lbs. (43 Nm).
  18. Remove the two lug nuts retaining the rotor.
  19. Install the wheel and tire assembly, aligning the marks made during removal.
  20. Carefully lower the vehicle, then firmly depress the brake pedal 3 times to seat the pads against the rotors.

SOURCE: I have a 96 Olds Cutlass Supreme that intermittently won't start

If the lights on the dash all come on but the engine wont turn over it could be a problem with the VAT security system. Your key has a little chip on it between the teeth and the handle. This is a common problem with GMs', often just replacing the key is necessary but sometimes the VAT module needs to be replaced.

SOURCE: I need to know how to put rear struts on a 96 olds

I just had to do this to my cutlass supreme. It is fairly easy. First, you need to jack the car up in the rear (but dont forget to put wheel chocks in front of the front wheels to prevent any chance of rolling, and break all of the lug nuts loose while the car is still on the ground, and put jack stands under it to keep the car raised safely) and remove the rear wheels. Then look at where the strut mounts to the wheel, there are two bolts holding it on the wheel assembly; remove those (you may need to jack ut the suspension to remove the bolts). Now locate the two smaller bolts to each side of the the strut itself on the strut mount, holding it to the car (this is located at the very top of the wheel well) and remove them. Now u can compress the strut by hand and wiggle it free from the car. Once u have the old strut out, remove the large nut that is securing the strut to the mount. In some cases this is impossible to do due to the rust that has binded them together. If this happens, you will need to purchase a new strut mount for your new strut. AutoZone seems to be the cheepest place for parts. To install the new struts just do everything backwards. When the new struts are installed, the wheels may be slanted down. If this is the case, do not worry, they just need time to "relax" or be broken in. I hope everything goes smoothly and i wish you luck.

My 1985 Olds cutlass won't start and the engine keeps flooding. I get a strong oudour of gas as well.


Every time you try to start it, it dumps fuel. Pull a plug wire and check for spark. If you have spark. replace the plugs, they are fouled out. If no spark, look at the crank sensor, ignition module, coil, cap and rotor. You will still need to replace the plugs..

Oxygen sensor replacement


The oxygen sensor is located approximately 10 inches down the exhaust manifold. It looks like a spark plug with wires coming out of it. Most of the time there are two or more depending on which motor you have. Hope this helps!

Rear spark plugs how to get. to them 93 olds cutlass supreme


You have to disconnect the air duct, remove the recovery bottle and place aside with removing any hoses. Remove the torque strut to engine bolts. Push the struts out of the way then use a pry bar to rotate the engine forward. You can put the pry bar in the passenger side bracket for leverage. Then use a ratchet strap to hold the engine in place.

Change rear spark plugs 1994 cutlass supreme 3.4


If you got small hands and long arms, you can change the rear spark plugs with the right extensions and swivel spark plug socket. You can get to all three from the top and leaned over the passenger side of the car.
If you need more room, your going to have to tilt the engine forward. Here is how it's done, with the transmission in park and parking brakes on with a block at the BACK wheels. Undo the two dog bone motor mount at the front of the engine, once disconnected with a friend.
Push the car forward once your release the parking brakes, push it just far enough that you tilt the engine forward and not in to the radiator. Once that is done, put on parking brakes and place block at the BACK wheels again, so we don't lose an arm.
This should give you more room to get to the rear spark plugs and yes everything is done by touch to get the plugs out and most likely your going to have to replace the spark plug wires. The old ones will be harder to remove then the front ones and a spark plug wire pliers will works best to removing them.
Thank you for using fixy and be safe, after spark plugs replaced, just reinstall everything the revers.

Falls dead when driving, will restart after awhile


Did you try checking or replacing the coolant sensor? I think you should replace it along with the thermostat. Are there any problems like sputtering or any unusual noises or symptoms? Smoke, anything?
