How to repair the front .crankshaft seal on a 97 Chrysler Concorde

SOURCE: 1995 Chrysler Concorde transmission diagram

There are 3 places it could be coming from. (1) The outer rubber seal on the pump between it and the case (2) The metal clad seal in the center of the pump that seals against the converter hub (3) And, the 5 bolts that hold the pump in have washers under them. The seal around the outside likes to get hard and brittle with age, especially if it has gotten hot before, leading to cracks that leak. The converter seal will wear naturlaly from doing it's job and more so if the pump bushing is wore out. The bolts that hold the pump in can get loose because of vibration letting oil out around the threads and out into the world.

If you pull it out and don't find loose bolts or obvious signs of a leak, then I suggest changin out all the places I mentioned. If you take the trans out and tip it on it's ****, then the pump comes out with a couple slide pullers. Be careful not to let the clutch-pack(inputshaft) slide out any, this will make going back together easier. There is a gasket between the inside of the pump and the case that will most likely need replaced too so get that as well; it seals all the ports and passages around the pump. Replace the outer square "O"-ring and the metal clad seal in the middle, then lube the outer seal and set the pump in place. Line it up and drive it in with the handle of any hammer. Torque it down(23ft. lbs.) with new washers for the bolts or new bolts with integeral washers. Be sure to loctite the threads as well to prevent them loosening up. Wiggle turn the input shaft to double check it isn't bound up and then just put it back in the car.

It sounds like a pain and it can be, but, it's easy after you do a couple thousand. Just like falling off a log. Hopefully you just have to do it once.

they are behind the cam shaft gears you have to remove then and put the car back in time you might want to go down and get a book to show you timing marks

SOURCE: how to replace Honda front Crankshaft Seal

Have to take off the crankshaft pulley to get at the Crankshaft Seal.

Use a hooked seal remover to dig in and pull the seal out without damaging sealing surfaces.

Need to get at the crankshaft seal, usually by removing the crankshaft pulley and using a seal remover to take out the old seal, then put a new seal in.

Here are some instructions on how to do the 'rear' seal:
Rear Main Seal Removal & Installation 2.4L, 3.3L & 3.8L Engines To Remove:

1. Remove the transaxle and flexplate. CAUTION
   Make sure not to damage the crankshaft sealing surface when removing the oil seal.
   
2. Insert a flat-bladed pry tool or equivalent through the dust lip at an angle.
3. Carefully pry the oil seal out of the engine. Pry against the chamfered edge of the crankshaft, do not damage the sealing surface of the crankshaft or an oil leak may occur.

1. Place special tool 6926-1 seal guide or equivalent on crankshaft.
2. Place the seal on the guide. Make sure the seal lip is facing the crankshaft and the guide tool remains on the crankshaft. Rear crankshaft seal installation (2.4L engine shown, 3.3L & 3.8L engines similar)
   
   CAUTION
   Do not drive the seal into the block past flush. An oil leak may occur.
   
3. Drive the seal into the block using a seal driver or special tool 6926-2 and handle C-4171 until the tool bottoms out against the block and the seal is flush.
4. Install the flexplate and transaxle.

1. Remove the transaxle and flexplate. CAUTION
   Make sure not to damage the crankshaft sealing surface when removing the oil seal.
   
2. Remove the oil seal with housing from the rear of the engine block.
3. Remove the oil seal from the housing.

1. Clean the sealing surfaces on the seal housing and engine block.
2. Use a commercial seal installer to install the seal in the seal housing.
3. Apply a light film of motor oil to the seal lip.
4. Apply silicone sealant to the oil seal housing sealing surface and install the housing with seal on the engine block. Tighten all bolts to 104 in. lbs. (12 Nm).
5. Install the flexplate and transmission.

SOURCE: Where is the Fuel Pressure

The intake manifold plenum must be removed to service the fuel pressure regulator on the 3.5L engine...



Fig. 4: The fuel pressure regulator is located in the rear of the fuel rail on the right side (click image for zoom)

Fig. 5: Carefully pry the regulator from the fuel rail

Hope this helps (remember to rate this answer).
