Replace spark plugs in 1999 oldsmobile

Depends on which engine you have and model of olds. If its a V6 they are on each side of the engine, follow the spark plug wires from the coils. If its a 4 cylinder then they will be located under the cover on top of the engine, olds liked to use the quad 4 motor and to access those take off the 4 bolts that hold the top cover on the engine and disconnect the connector at the end of the cover on the drivers side. Then lift off and there they are.

Where are the spark plugs located on the 1999 Intrigue???

Your Intrigue is equipped with the 3800 V-6 motor...The motor is mounted transversely...(sideways:) You can trace the spark plug wires from the spark box to each of the 6 plugs...I recommend you use AC platinum tip plugs, verify the gap...should be 45 mm...spark plug gap tools are inexpensive and available at all parts stores...Use thread lubricant...and plug wire tip lubricant...As your mileage is over 80,000 you should also consider replacing the wires too...:)

Hi. here's the procedure on how to replace your spark plugs. Spark plug location is in this procedure.

  • Park the car in cool, shady area and allow the engine to cool.
  • Step 2 Remove the parts of the Grand Am engine that hinder access to the spark plugs. For a 2.2 L engine, remove the ignition coil housing. For a 2.4 L engine, remove the bolts that hold the retaining ignition coil and disconnect the electrical connector. Pull the assembly straight up and away from the engine to remove it. For a 3.1 L engine, remove the air cleaner. For a 3.4 L engine, remove the windshield wiper module cover and rotate the engine for service access to the rear spark plugs.
  • Step 3 Locate the spark plug wire and grab it by the spark plug boot. Twist the boot in both directions and pull back to remove the wire.
  • Step 4 Insert the spark plug socket over the old spark pull and unscrew it from the cylinder well. Remove the old spark plug.
  • Step 5 Lubricate the threads of the new spark plug and screw it into the cylinder well.
  • Step 6 Test the tension and adjust it to the required setting. It needs to be 15 ft-lbs. for a 2.2 L engine, 16 ft-lbs. for a 2.4 L engine, 13 ft-lbs. for a 3.1 L engine, and 11 ft-lbs. for a 3.L engine.
  • Step 7 Reconnect the spark plug wire and twist it to lock the plug in place.
  • Step 8 Repeat Steps 3 through 7 for the remaining spark plugs.
  • Step 9 Replace all of the parts that were removed from the Grand Am in Step 2 to reach to the spark plugs.

    Location of spark plugs

    The spark plugs are located in the front upper half of the motor (4 of them). Each spark plug has a spark plug wire connected to it. The spark plug wires run from the drivers side of the engine to the spark plug so just follow the wires to each of the spark plug locations.

    Auto repair --1999 gmc k1500 pickup old body style 5.7 liter v8 350 i removed the distrubutor after changing a intake manafold gasket. put back together and it is timed correctly but the engine is missing....

    This procedure sounds correct as long as the timing is set correctly. You can locate this particular plug, usually on the firewall in line with the harness. It will simply be a plug that goes to nothing and has a cap in it to close the circuit when not setting timing. Hope this helps, good luck!

    Need to know where spark plugs are located in order to change

    Follow the spark plug wires down into the engine, a soft tug should pull the wire loose from the plug and then you will need a spark plug socket to change them.
