Accord to the shop manual... real simple. LOL
Disconnect negative battery cable(s).
Remove intake manifold.
Remove exhaust manifold.
Remove timing chains.
Disconnect heater hoses.
Remove cylinder head bolts in sequence.

Remove cylinder head and gasket.

Check cylinder head for warpage, cracks and damage. Ensure proper gaskets are installed.
Right and left cylinder head gaskets are not interchangeable.
Rotate crankshaft 90 degrees counterclockwise from vertical position.
Ensure no piston is at TDC.
CAUTION:Position camshaft so valves DO NOT extend below cylinder head surface, or ensure Camshaft Positioner (T93P-6256-A) and the Camshaft Positioning Tool Adapters (T92P-6256-A) are installed before installing cylinder head.
Install NEW cylinder head bolts.

*** DO NOT reuse bolts. ***

Coat bolt head-to-cylinder head surfaces with engine oil. DO NOT oil threads of cylinder head bolts. Ensure rear cylinder head bolts are installed in cylinder head and secured by rubber bands before installing cylinder head.
Install cylinder heads.
Tighten cylinder head bolts to specification and in sequence.

Step 1 28-31 (38-42)
Step 2 Additional 85-95 Degrees
Step 3 Loosen 360 Degrees
Step 4 28-31 (38-42)
Step 5 Additional 85-95 Degrees
Step 6 Additional 85-95 Degrees

If camshaft positioner was not used during cylinder head installation, rotate camshafts using flats matched at center of camshaft until both cams are in time. Install Camshaft Positioner (T91P-6256-A) on flats of camshaft. This will prevent camshafts from rotating.
Rotate crankshaft 45 degrees clockwise. This will position crankshaft so cylinder No. 1 is at TDC.
DO NOT rotate crankshaft past TDC position.
Timing chains can now be installed.
To install remaining components, reverse removal procedure.

anything else you need let me know

Need step by step diagrams to replace cam sensor

Camshaft Position (CMP) Sensor


3.0L (VIN S) Engine

Front of the engine attached to the forward cylinder head.

3.0L (VIN U, 2) Engines

Ford Sable, Taurus 2000-05
Camshaft Position Sensor


Description & Operation

The Camshaft Position Sensor (CMP) is a variable reluctance sensor that is triggered by a high point on the left-hand exhaust camshaft sprocket. The CMP sends a signal relating camshaft position back to the PCM which is used by the PCM to control engine timing.
The CMP sensor detects the position of the camshaft. The CMP sensor identifies when piston No. 1 is on its compression stroke. A signal is then sent to the PCM and used for synchronizing the sequential firing of the fuel injectors. Coil-on-plug (COP) ignition applications use the CMP signal to select the proper ignition coil to fire. The input circuit to the PCM is referred to as the CMP input or circuit. DTC P0340 is associated with this sensor.

Removal & Installation

3.0L (VIN S) Engine

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Disconnect the battery ground cable.
  3. Remove the electrical connector.
  4. Remove the bolt and the CMP sensor.
  5. To install, reverse the removal procedure.

  2. Disconnect the battery ground cable.
  3. Remove the pin-type retainers and remove the accelerator cable snow shield.
  4. Detach the spark plug wire retainer.
  5. Detach the wiring harness from the intake manifold support.
  6. Release the fuel charging wiring harness from the valve cover studs. Position the wiring harness away from the camshaft position sensor.
  7. Disconnect the electrical connector.
  8. Remove the screws and the CMP.
  9. To install, reverse the removal procedure.
    NOTE Make sure that the fuel charging wiring harness is fully secured to the valve cover studs.

Fig. Testing the VPWR circuit of the CMP sensor

  1. Check voltage between the camshaft position sensor terminals PWR GND and CID.
  2. With engine running, voltage should be greater than 0.1 volt AC and vary with engine speed.
  3. If voltage is not within specification, check for proper voltage at the VPWR terminal.
  4. If VPWR voltage is greater than 10.5 volts, sensor may be faulty.

  1. Before servicing the vehicle, refer to the Precautions section.
    WARNING Use only a high-impedance multimeter, otherwise damage to the PCM and/or sensors can result.
  2. With the key OFF , disconnect the CMP sensor harness connector.
  3. Measure the resistance of the CMP sensor.

    3.0L Engine: 250-1000 ohms
  4. If the resistance measured is outside the limits given, replace the CMP sensor.

Where is the starter relay on a 98 ford explorer limited edition 6 cylinder 4.0? My book says on the fender next to battery but it is not there

The information you have is correct. The POSITIVE battery terminal connects to it. Just follow the battery cable and you will find it.

There are two different 4.0L V-6 engines used in Ford Explorers in the 1998 model year.
One is a Dual Overhead Cam (DOHC) engine. (VIN code "U")
The other is and Overhead Valve engine (VIN code "X")

What "VIN code" means is that the 8th digit of your VIN will be either a "U" or an "X". The 8th digit in the VIN identifies the engine that the vehicle is equipped with. You may want to use this information anytime you are talking about your truck or trying to get information or parts. These two engines are COMPLETELY different, so it can save you a lot of frustration if you give the correct information. Otherwise someone may just "assume" it is one or the other and you will get incorrect information or wrong parts.

Anyway, the actual location of the starter relay is the same for BOTH engines. The only difference is the type of cable hook-up that is on them. (see pictures below)

Where is the engine number located on a ford mustang engine 6cyl 2001?

For 2001 Ford Mustang 3.8L SFI 6cyl engine, with which your specific vehicle is equipped, can be most easily identified by the Vehicle Identification Number (VIN), located on either the VIN tag, mounted in the upper left-hand corner of the instrument panel, or on the vehicle certification label, located on the driver-s side door pillar. The engine identifying code is the 8th digit of the VIN. The engine VIN codes are as follows:


FIG: Engine identification codes may also be found on a label affixed to the left side rocker arm cover

4-3.8L SFI (OHV) engine N-4.0L SFI (SOHC) engine H-4.6L SFI (SOHC) engine V-4.6L SFI (DOHC) engine
X-4.6L SFI (SOHC) engine

Hope helps.

Ford e250 van running very poorly. Left engine bank has a place for two vacuum lines to be connected. Only one is present. Should there be two or just a plug on the open metal connection. Where do they...

There are four different engines that were installed in 2002 E350's. your question is very hard to answer without knowing which one you have.
The 8th digit in your VIN will identify exactly which engine you have.

V6-4.2L VIN code (2)
V8-4.6L SOHC VIN code (W)
V8-5.4L CNG VIN code (M)
V8-5.4L SOHC VIN code (L)
