Spark plugs


Check this SPARK PLUG REPLACEMENT - REMOVAL PROCEDURE

1_23_2012_5_10_32_pm.jpg

1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
Packs off and precede with step 2 from here.
2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
when using compressed air, as flying dirt particles may cause eye injury. NOTE:
Clean the spark plug recess area before removing the spark plug. Failure to do so could
result in engine damage because of dirt or foreign material entering the cylinder head, or
by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
cause the plug threads to seize, causing damage to cylinder head threads.
4. Inspect the spark plugs.

INSTALLATION PROCEDURE

1_23_2012_5_11_30_pm.jpg

1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
to the gap specifications. NOTE:
• Use only the spark plugs specified for use in the vehicle. Do not install spark
plugs that are either hotter or colder than those specified for the vehicle. Installing
spark plugs of another type can severely damage the engine.
• Check the gap of all new and reconditioned spark plugs before installation. The
pre-set gaps may have changed during handling. Use a round feeler gage to ensure
an accurate check. Installing the spark plugs with the wrong gap can cause poor
engine performance and may even damage the engine.
2. Install the spark plugs to the cylinder head. NOTE:
• Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
cylinder head. Cross-threading or failing to fully seat the spark plug can cause
overheating of the plug, exhaust blow-by, or thread damage.
• Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 18 N.m (13 lb ft).
3. Install the ignition coils.

TSB#05-06-02-012B: Service Engine Soon (SES) or Check Engine Light On, DTC P0480, P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness) - (Oct 19, 2006)
Subject:
Service Engine Soon (SES) or Check Engine Light On,
DTC P0480/P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness)
Condition
Some customers may comment that the Service Engine Soon (SES) or Check Engine light is illuminated. This condition may be intermittent and upon investigation, the technician may find either DTC P0480, P0526, P1481 or P1484 set.

Cause
This condition may be caused by the cooling fan harness chaffing against the plastic guide it routes through. This
contact may damage the insulation of the wires enclosed in that harness.

Correction
Replace the engine cooling fan harness using the procedure listed below.

1. Remove the cooling fan. Refer to the Cooling Fan and Shroud Replacement procedure in the Engine Cooling sub-section of SI.

2. Place the cooling fan assembly on a bench.
Disconnect the harness electrical connector from the cooling fan clutch.

3. Remove the harness from the plastic guide while feeding the wires out of the slot.

4. Before installing the new harness, wrap the affected area on the wires with electrical tape to keep the protective sleeve in place. Be sure to keep the tape approximately 25 mm (1 in) away from the connector so the wires can be fed into the slot.

5. Feed the wires into the slot and install the harness to the plastic guide.

6. Connect the harness electrical connector to the cooling fan clutch.

7. Install the cooling fan. Refer to the Cooling Fan and Shroud Replacement procedure in the Engine Cooling sub-section of SI.

I need to replace the alternator in a 1996 Dodge Grand Caravan


Disconnect the negative battery cable with a socket wrench. Remove the windshield wiper module for 3.0 L and smaller engines or the right front lower splash shield for engines larger than 3.0 L. Remove the accessory beltdrive with a socket wrench. You will also need to remove the lower bolt and wiring harness from the oil dipstick tube with a socket wrench if you have an engine larger than 3.0 L.
Take the mounting bolts off of the alternator with a socket wrench and disconnect the alternator's electrical harness. This will allow you to remove the alternator assembly.

Install the new alternator assembly and connect the electrical harness. Tighten the mounting bolts to 40 foot pounds with a torque wrench and install the accessory drive belt. You will also need to install the lower bolt and wiring harness from the oil dipstick tube with a socket wrench if your engine is larger than   3.0 L.

Connect the windshield wiper module or right front lower splash shield as required. Connect the negative battery cable with a socket wrench.

Good luck and hope this helps.
I have heard the easiest way to remove the alternator is to remove the exhaust manifold. It will cost about $15.00 or so for a new manifold gasket but it is supposed to create enough room to be able to swap it without the hassle of removing alot of parts.

I need some info on the were abouts,and how much im gittin in over my head with changein the crankshaft positioning sensor on my 1994 lexus LS 400?


It's not too bad of a project. Your CPS (Crankshaft Position Sensor) is located in the engine compartment, front engine area / driver's side, mounted in the engine block above the crankshaft pulley. I've provided a photo below to give you a better idea of what your looking for.

5c959ad.jpg
To remove the CPS, simply disconnect the wire harness and remove the mounting bolt. From there, the CPS should slide right out.

When installing your new CPS, make sure to check the tip to ensure it came with a new spacer (will be attached to the tip). Thereafter, install the sensor until the spacer lightly touches the sensor ring. Tighten the sensor mounting bolt to approximatley 105 in.lb. and attach the wire harness.

Help this helps and good luck!
