I know of no diagram for this are of the Z. Pulling back the carpet and hammering with mini sledge hammer is my suggestion. It's impossible to get a full swing but you can use the hammer as a ram rod and thrust the top of the hammer into the dent. You can also use a sold long shaft that has a thick diameter and semi rounded end to use as a drift (hammering down on the shaft while positioning the shaft over the dent in different areas as it gets knocked into shape. I have a 1 1/2" aluminum shaft that I bench grinded for a different purpose but would work for this. If you can't find a good solid metal shaft then using an oak 1"x1" thick or thicker board from a hardware store will work. Just sand the end into a slightly convex shape will work. There are no wires that travel under the carpet but check for any brake lines on the under side that might have been bent up as well. Without seeing the extent of the damage it's hard to say what is affected by the dent. The brake lines are not directly under the clutch pedal but hammering the floor board back into shape could affect them if the dent was large enough. Bake lines are not something you want to try and re-bend into shape. I'm sure not sure if you are making them pay for this damage but I would be having the shop that did this pay for it getting fix or at least having them hammer it back into shape. The floor boards are metal but weak part compared to the sub frame they are attached to so I doubt the sub frame was pushed up any. I would not suggest pulling the floor board down from the underside as this would involve unnecessary drilling of holes to attach anchors. It wouldn't hurt to get the alignment checked afterwords (on their dime hopefully).

Testimonial: "Sadly, it was a relative trying to do me my wife a 'favour' so no recompense is likely. Have tried the sledge hammer nbut cannot get at the worst spots. Am trying the 'drift' method (with t-tops off to give better targeting) now but it is very slow going. Next problem will be the area right below the drivers seat. It is pushed up to the point that the seat rails are no longer straight. Thanks for mentioning the brake lines. Hadn't thought of that. Sub frame appear fine but will be after a wheel alignment as soon As I can get the car drivable again. Thanks so much for you reply. Much appreciated."

How do you remove oil pan on 1993 Isuzu trooper 4x4

you have to make to unbolt the engine mountings,drain the radiator and remove the upper & lower radiator hoses and get the radiator out just to avoid any damage because you are going to lift the engine quite up so you could remove the engine oil pan over the front differential axle. Check whether is there any small pan cover where you can remove to have access into the oil pump and remove it.Would be much easier if you remove the oil pump.

How do I remove automatic transmission from 1993 Chev 2500 pickup?

TRANSMISSION REMOVAL IN STEPS.
The Drive Shaft
  • Using a 1/2-to-2-ton floor jack, lift the front of the truck and place jack stands under the frame. Once the truck is lifted enough for you to safely move around under it, begin removing the four bolts connecting the U-joint between the drive shaft and the rear axle. When you pull the drive shaft out of the tail shaft, transmission fluid will pour out of the tail shaft, so place a drip pan or oil-changing pan under the tail shaft of the transmission.
Lines And Linkage
  • If the truck is an automatic, you will need to remove two transmission lines from the passenger side of the transmission by the bell housing close to the transmission dip stick. If it's a manual transmission you won't have those lines, but you will have shifting linkage on the driver's side of the transmission. Depending on the year of the truck, the linkage is held on by either a cotter pin or locking-sleeve washer. You will also need to remove the speedometer cable. If it's an older truck, it will be a hard-cased cable similar to the emergency brake cable that threads onto the driver side of the transmission just before the bell housing. If the truck is a newer model, it will be an electrical set of wires attached to a plug on the tail shaft.

Remove From Engine
  • Remove the transmission mount bolt that holds the tail end of the transmission to the cross member on the frame. You will need to either use wood blocks or a jack to support the weight of the transmission. Take out the nine bolts on the bell housing that attach the transmission to the engine--there is one on the top center of the bell housing, two along each side of the bell housing and two on each side at the bottom next to the guide pins.
Remove From Vehicle
  • Once removed, maneuver the transmission to the rear of the truck about 6 inches until it clears either the clutch kit of a manual or the torque converter of an automatic. When the transmission is free, lower the bell housing end of the transmission down until the tail shaft is clear of the cross member.

  • Park the vehicle on level ground and shut off the engine. Raise the front end of the Escort off the ground using the floor jack. Lower the vehicle onto jack stands placed under the frame to support the car.
  • 2Place the jack under the oil pan and raise the lift plate to the bottom of the oil pan. Remove the engine mount bolt using the 1/2-inch socket wrench. The engine mount bolt is in the center of the mount fitting in clear view.
  • Slowly raise the engine using the jack until the weight of the engine is removed from the engine mount. Pull the engine mount from the fitting and place the new mount in the fitting.
  • 4Lower the engine slowly and insert the bolt into the mounting hole. Tighten the mount bolt to 67.9 foot-pounds using the torque wrench.
  • 5Remove the bolt from the other engine mount the same way as the first one. Pull the mount from the fitting and insert the new one. Replace the bolt to the center of the mount fitting. Lower the engine to the frame and tighten the mount bolt to 67.9 foot-pounds.
  • 6Remove the jack from under the Escort. Raise the car off the jack stands, remove the stands and lower the car to the ground

    How to change transmission filter on a 1997 grand am GT

    The filter is located inside the transmission pan. I prefer to do this procedure with the vehicle sitting level up on four jack stands. Position the jack at the lower body flange and at the center of the vehicle towards the front slightly. lift the vehicle in the air high enough to install two jack stands at each end of the body at the lifting pads. lower the vehicle onto the pads. roll the jack under the body and lift the other side up to the same height and place the other two jack stands in the same place on the other side. Place a large pan under the transmission pan and loosen all the pan bolts but do not remove them yet. Fluid will start to run out of the sides of the pan. Slowly loosen the bolts that are farthest away from you while holding the pan with your other hand. Drain more fluid out by slowly lowering the pan with your other hand. Once the fluid has stopped coming out, press the pan back up against the transmission and remove the rest of the bolts. Lower the pan straight down and place it in the drain pan. The filter should now be visible. It will either be held in by a single bolt or press fit into place. This is a messy job so, wear old clothes and always wear safety glasses when performing this procedure.
    CAUTION : Use quality jack stands for this procedure. The gasket is usually reusable.

    1999 grand voyager le how do i replace fuel filter

    Hello,

    To replace the fuel filter of Your 1999 grand voyager, please follow the steps below, You will be in need of these instruments, Line wrench set, 3/8-inch ratchet and socket set, Replacement fuel filter kit.
    1. Park the 1999 Grand Voyager in a ventilated area and engage the emergency brake,
    2. Walk to the back of the 1999 Plymouth Grand Voyager and completely unscrew the gas cap from the fill neck on the gas tank. Taking the cap off will remove the pressure in the fuel filter.

    4. Slide under the passenger-side rear of the van behind the tire. Locate the fuel filter that is mounted to the upper part of the gas tank. This type of fuel filter has three fuel lines coming out of it.
    5. Position the drip pan under the gas tank in the general vicinity of the fuel filter. Using a clean rag, compress the fuel lines on the ends. The fuel lines are held to the fuel filter by a plastic clip. Compressing the end of the fuel line will unlock the fuel line from the clip. Pull out on the fuel lines. Do this to all three of the fuel lines.
    6. Remove the bolt from the fuel filter bracket with the 3/8-inch drive ratchet and a 3/8-inch drive socket. Then, pull the fuel filter out of the bracket and put it into the drip pan.
    7. Position the new fuel filter into the bracket. Screw the mounting bolt in and tighten it down tight with the ratchet and socket.
    8. Push all three fuel lines onto the appropriate fuel filter ports. Hook the fuel lines to the same fuel filter ports that they were hooked to on the old filter.

    Does a 1991 chevy s-10 blazer have inline fuel pump?

    1. Place wheel chocks behind the passenger side wheels, and lift the driver side of the Blazer with a floor jack. Place jack stands under the frame, and lower the vehicle onto the jack stands. Supporting the truck with the jack stands in this manner prevents injuries that occur if the floor jack fails.
    2. 2 Remove the fuel filler cap, and turn the ignition key to the off position. This relieves some of the fuel pressure on the system, and prevents the fuel pump from starting when the filter is removed.
    3. 3 Locate the fuel filter on the driver side frame rail, just behind the front door. The filter is a cylindrical shaped part, about six inches long, that's in the fuel line on the inside of the frame rail.
    4. 4 Place a drain pan under the filter to catch any fuel that spills. Loosen the filter fittings by using a 21mm wrench to hold the filter while turning the flare-type nut on the line with a 16mm wrench. Remove both sides of the fuel line from the filter and drain it into the drain pan.
    5. 5 Check the rubber O-rings located on the fuel line ends for tears and nicks. Replace any O-ring seal that shows damage. These seals are available at your local auto parts store.
    6. 6 Insert the fuel lines into the ends of the new filter, and thread the flare-nuts into the filter by hand. Be careful not to cross-thread them and cause the need for replacement fuel lines. Tighten both lines with the 21mm and 16mm wrenches.
    7. 7 Raise the truck off the jack stands with the floor jack, and remove the stands from under the vehicle. Lower the Blazer to the ground. Reinstall the fuel filler cap.
    8. 8 Turn the ignition key to the "Run" position--and then back to the off position--three times to prime the new filter. Each time the key is turned to the "Run" position, the on-board computer turns the fuel pump on and opens the injectors to add fuel for starting. Start the engine and check for fuel leaks.

    This has an electric fuel pump located in the gas tank.

    To replace or check it you do one of 2 things. You can drop the tank or cut a hole in the cargo area to gain access as they are on the top of the tank.I would not suggest cutting hole

    Where can i put jack stands to do an oil change?

    There are (2) three and a half inch long jack pads on both sides of your vehicle along the frame rail located exactly twelve inches behind each of your front wheel assemblies. You can place your jack stands safely there. Your oil filter is located on the passenger side of the vehicle, so you'll need to remove the oil filter by accessing it right above the lower control arm using a three-pronged oil filter wrench and a 9" extension with a ratchet.

    IMPORTANT! : Always replace the oil drain plug gasket with each lube, oil and filter service. (it looks like a copper or aluminum washer)

    P.S. - Don't forget to adjust your tire pressures to 30 p.s.i. in accordance with the tire placard located in the driver side doorjamb.
