Tip & How-To about Saturn L300

How to change spark plugs on a 2002 Saturn L300

This is a difficult car to change them on so i have provided a guide to help people out.Tools required:


1 Crescent Wrench 1 "5/8 Spark Plug Socket 1 "3/8 Drive Ratchet 1 "3/8 Drive Extension 1 "1/4 Drive Ratchet 1 Pair of Small Channel Lock Pliers 1 Inverted Torx Socket Set
Even if you do not own any tools at most you should spend about $75 for the tools required to do this task.

Looking down at the engine you will see the two intake manifold runners and four boots for each one. Each boot has two clamps. The easiest way to take them off was to use a pair of small channel lock pliers to squeeze the clamp enough to unlatch the clip. they make a special tool for this, But its not really worth the money.



The front manifold is a little easier than the rear one. there are only three bolts that need to be unbolted and the manifold should slide off.


Now there are two bolts that need to be removed and the coil packs can be slid out.


The front spark plugs are now exposed and can be changed.

The rear is a little more tricky because there is more that needs to be removed off of the manifold. The PCM can either be unbolted or unplugged. Whichever method you choose you may be required to use the re-learn technique for the pass-key system. There are two vacuum hoses that go to a black box that need to be removed. There is a brass fitting that is holding a larger vacuum hose onto the manifold. There is a sensor that needs to be unplugged on the right side of the manifold. there are four bolts that hold the manifold down. there are 4 total and two are in the back of the manifold.


Now you should be ready to pull off the manifold. Make sure there are no more harnesses or sensors attached to the back of the manifold. It looks like there is one or 2 from the manual. Pull the manifold off and you will expose the coil pack. Unbolt it just like you did the front and pull the coil packs off to expose the rear spark plugs. Change your spark plugs and put everything back reverse of the install.

Some tips. I find its best to take ziploc bags and put bolts for specific steps and mark them with a permanent marker so you do not confuse them. Also it helps to take pictures with a digital camera on each steps so you know how it looked before you put it on.

remove PW steering hose


Hi,

The tools required are :-

  • Large crescent wrench
  • Small crescent wrench
  • Drain pan
  • Shop towel
A Generic Procedure ( This example is for Other brand but might help you, if needed ) is :-

Step 1

The power steering pump is located on the right fire wall of your vehicle. Place the drain pan directly under the power steering pump and use your small crescent wrench to open the drain plug by turning it counterclockwise until removed. Take care that the car has had time to cool so that you do not burn yourself with the hot fluid. Allow the fluid to drain until it is slowly dripping.

Step 2

Use your large crescent wrench to turn the power steering line nut counterclockwise until it is completely loose. The line will not come off at this point.

Step 3

Use your large crescent wrench to turn the bottom power steering line nut counterclockwise until free. Pull slightly upward and free the line from its seat. Both ends of the line will now come free and the line is removed.

Step 4

To replace the line, use the same procedure in reverse. Put the drain plug back in and add the appropriate amount of fluid.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

changing spark plugs 2003 Impala 3.4 eng. i.e. removing and reinstalling upper intake manifold


I have a 2003 chevy Impala and it's not so difficult. Try using a small ratchet that fits in the palm of your hand, I can't remember what it is called. To install the plugs use an extension and put a couple of the card board pieces from one of the spark plug boxes in between the new spark plug and the spark plug puller socket, this will hold the new plug in place while you work with the extension. When screwing in the plug you will have to go by feel so move the extension back and forth like a light jiggle while turning to avoid cross threading the plug. After the plug is tightened attach the ratchet and slightly torque into place.
