They are under the intake, located in the top of the valve covers. To remove the inake you first take the air cleaner off then you will need a torx socket a T30 (male type) and it must be a 1/4" drive and you'll need a 6" 1/4" drive extension to remove the intake bolts there is 5 on the inner side of the intake down (inside of the holes) & one on the outside of the intake (by the throttle body) to be removed. there is no need to disconnect anything else, I just proped the inake up with a screwdriver while removing the coils (which are plugged directly into the plugs) then simply remove the plugs with a 5/8 spark plug socket and replace. plug your coils back in then put intake back on....hope that helps you

You can go to www.autozone.com and select your vehicle at the top of the page. Once you have done this, go to the bottom of the page on the left side. It will have repair info. Select it, it will go to the next page where you will want to select the middle one for intermediate. This will give you the manual for free. It will show you diagrams of what you need to do to change the plugs.

The spark plugs are located under each coil. You will need to remove each coil to access the spark plugs. Look under the coilpack/ignition module and disconnect the wiring plug on the right side and remove the four 10mm bolts that hold the coil pack to your valve cover and pull up hard on it so the boots don't get stuck in the head. Now remove the spark plugs with a ratchet and spark plug socket

    White smoke is caused by coolant or water coming out the tail
    pipe. There is a chance that the white smoke was caused by water splashing
    up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in
    the radiator in any event.

    The white smoke is caused by coolant in the exhaust
    that may have gotten there when the head gasket blew originally. Running the
    engine for half and hour to warm up the exhaust, should get rid of the coolant.
    If the white smoke continues, then you have more problems with the engine. Some vehicles requires adding a block sealer to the cooling system when the head gaskets
    are replaced.

    Keep us updated.

    A thick white smoke from the tailpipe can mean only one thing (auto
    trans) - your engine consumes your transmission fluid. This problem
    normally is an easy fix.


    I don't remember antifreeze to cause very thick white smoke. But in case
    of antifreeze in the engine it is easy to check. Unscrew your engine's
    oil depositor lid. Turn it bottom side up and look for thick deposits. Check your coolant and transmission fluid levels. This might tell you what your car is consuming.

    The vapor that comes out of the exhaust when the car is cold is
    normal. It's a thin vapor that usually curls up over the car and
    dissipates. As Car Talk explains in the link in the "Learn more"
    section, the vapor is caused in part by the temperature of the exhaust
    system, and when the exhaust system is at a warmer temperature, the
    vapor will stop. Sometimes it's so cold outside that the thin white
    vapor coming out of the tailpipes won't stop, and that's OK, too.



    If there's a heavier white smoke coming out of the tailpipe, that's
    usually the sign of an engine problem, typically when coolant/antifreeze
    enters the combustion chamber because of a bad cylinder head gasket or
    another problem that ends up burning coolant.



    There are other signs that may point to a problem, including oil and
    antifreeze mixing and the engine, and oil on the dipstick showing a
    milky consistency. Also, if you're burning coolant, your coolant level
    may be low. If you suspect that there may be a problem, take it into a
    service center. Never take off the radiator cap when the engine is warm.

  1. Remove the large black cover from the engine by removing the bolts in each corner with a socket and ratchet. Lift the cover off and set it aside.

  2. Locate the spark plug wires. Three go to the front of the engine and three go to the back of the engine. Locate the plug wire that goes to the front right spark plug.

  3. Grab the boot (base) of the spark plug wire and pull up on it hard to remove it from the spark plug.

  4. Place a spark plug socket onto your ratchet and remove the spark plug by turning it counter-clockwise.

  5. Place a small amount of anti-cease compound on the threads of the new spark plug. Thread the spark plug into the hole by hand to avoid cross-threading the plug. Tighten the plug with the spark plug socket and ratchet.

  6. Press the boot of the spark plug wire back onto the top of the spark plug until it snaps into place.

  7. Place the black plastic cover back onto the top of the engine and secure it using the four bolts removed in Step 1.

Good Luck please accept the answer Sorry there is no pictures showing the exact location of the bolts

How do i get to the thermostat on my 2002 saturn vue v6 3.0 ltr


First you will need to remove the intake plenum, then the lower intake.

Remove the hose from the thermostat inlet housing.

Remove the bolt that holds the extension housing to the head near the oil dipstick.

Carefully jack up the passenger side of the engine and remove the t-stat extension housing.

Remove the thermostat housing bolts and remove the housing.

These are a real pain in the captain s quarters!

How To Change The Spark Plugs On A 2002-2005 Kia Sedona 3.5 Liter


You'll need to remove the oil cap and the 6 bolts holding on the engine cover. The front 3 spark plugs are pretty easy to replace. You'll need to unplug the spark plug wire from the coil and disconnect the electrical connector. Unbolt the 2 10mm bolts holding the coil to the valve cover. Twist the coil and boot back and forth and pull it out of the cylinder head. The spark plug is down in the head, you'll need at least a 6 inch extension with a 5/8" spark plug socket, a telescopic magnet will help get the spark plug out of the head. The back 3 spark plugs involve removing the upper intake and throttle body, unbolt the bracket to the throttle body, and the bracket bolted to the upper intake manifold. on the back side of the engine. Remove the tubing from the throttle body to the air cleaner box. Unbolt anything else bolted to the upper intake. Unplug electrical connectors to the throttle body and any other electrical connectors on the upper intake and remove the upper intake bolts. And move the upper intake out of the way, there are only spark plug wires on the back 3 plugs. Twist and turn each boot to aid in removing the boot from the plug. I would get a new upper intake gasket and consider replacing the wires at this time also. There are actually only 3 spark plug wires, so for what is involved to get to them, I would replace them. I have found alot of the wires will arc to the upper intake manifold.

Where ar the spark plug located?


That depends if you have a four or 6 cylinder engine...On a four cylinder they are right on top of the engine...there is a black coil pack on the top that has four 10 mm bolts and 1 plug holding it on. Remove the pack and the plugs are underneath... On a six cylinder they are under the intake It must be removed to replace the plugs

Under the intake manifold,  it will need to be removed.  Not too hard to do for the average diy but recommend buying a repair manual as a guide.  you will need a 1/4" drive T30 torx socket with a long extension one of the bolts is hidden but the others are under the black cover on the top of the intake.  you will also need to remove the coil pack held on with torx bolts.  8 or 10 inverted torx socket needed for that.

Plug replace


This is a outstanding question!!! The plugs or wires are not visible from the top or sides of the moter. You just can't see em'!!! You have to remove the large black plastic air intake. Then remove the intake manafold(not too hard to do) to access the spark plugs and wires.
Also: After removing all the black plastic air intake stuff, you'll have to remove the coil pack (long black plastic thing that says "Ecotek" on top). The coil pack is removed by disconnecting the wire connector on the driver's side end and then removing four bolts. To lift off the coil pack, you'll have to pull upwards firmly and evenly from both sides, because the spark plug boots or wires are holding onto the spark plugs as well as the coil. With the coil pack removed, look down into the silver channels - there's the plugs. To remove, you'll need a plug socket head and a socket wrench with long extension. To replace the plugs, I use an extra or old spark plug boot to hold the plug and get it started turning into the engine threads. Good Luck!

What are the steps in changing spark plugs on a 2002 saturn vue six cylinder suv


I think you bought the dreaded Opel v6 in your Saturn. If it has six rubber hoses on the intake tubes, thats the Opel. A couple of years later, Saturn started using Honda v6's. A royal pain to replace the plugs, suggest a repair shop because the intake has to come off.

Spark plugs on 2002 Saturn vue


just completed a plug removal and install on my '02 awd v6. if you have the time and patience it's straight forward; common sense was most helpful. to gain access to the plugs, both fore and aft, you must remove, in short, everything near to, associated with, the air intake system. common tools plus a 1/4 socket, with 8 inch extension to hold a #10 star bit. these star bolts are under the rectangular plastic plate atop the intake. once you have those out, disconnect all the wiring, carefully. lift the intake out, look for plug covers, fore and aft, ignition assembly lays atop each row of three plugs. with the hands of a surgeon, remove the ignition assembly, and by golly ye shall see your reward. easy from then on.
replaced my plugs with the iridium 'honeys'; marked improvement in starting, acceleration, smoothnes, noise, and gas mileage to the value of + 3.0%. changed out the oil with mobile1 extended performance, changed transmission fluid. took a shower. time involved, 7.0 hrs. dealer be damned,,priceless!
