Question about 2007 Toyota Corolla

2 Answers

I need advice on how to get the old plugs out of my 2007 Toyota corolla. I removed the coils and when I tried to put the socket in the plastic tube that houses the coil unit I could not get the spark plugs un-done because there is a rubber/plastic seal around the hex body of the spark plug that is preventing the socket from fitting around the plug. What do I do please???

Take off that rubber part and try again ..its just there to make it easy to remove the old plug..then use the coil itself to remove the old plug by just slotting it in and out to remove plug

CHANGING SPARK PLUGS 2002 TACOMA 4 CYLINDER


Starting on the pasenger side. Remove the intake tube running from the air filter box to the throttle body and disconnect enough tubes to swing it out of the way. The sparkplugs are down below the small coils you see at the end of the sparkplug wires. With a 10mm socket remove bolt holding the coil, disconnect the plug at the top of the coil by squeezing it at the top and pulling straight off the coils.

Pull the coil straight up. there will be about a 6 inch tube that connects to the top of the spark plug when inserted. You will need a 5/8 sparkplug socket and about 2 feet of extensions to make it easy on yourself. Insert the spark plug socket and extensions down the hole you removed the coils with the tube from and remove and replace the sparkplug. Reinstall your coil onto the engine and move to the next one until you have replaced all the plugs on the passenger side.

Make sure you reconnect all the plugs to the coils, hoses to the intake tube and reinstall your intake tube. The drivers side is a little easier. Pop the spark plug wires from their plastic holders to free enough slack to be able to pull your sparkplug wires out of the block. For the plug closest to the front of the engine you will need to remove the 10mm bolt holding the ground wires to the intake manifold to be able to free enough space for removing the plug.

For the middle plug you will need to remove the 10mm bolt holding the bracket that is holding one of the throttle cables at the top of the intake manifold. For the rear plug just pop the flexible hose that runs behind the black metal bracket straight up out of its clip and push it out of the way along with any other hoses that run through this area. Pull the spark plug wire from its place by pulling straight up just like with the coils. there will also be about a 6 inch tube running down to the spark plug at the bottom of these plugs.

Remove and replace the plugs same as before. make sure you reconnect all your hoses and wires to their previous locations. Doublecheck to make sure you reconnect all the ground wires/ brackets. Also you will need to use " twin ground electrode plugs" (see sticker on front of your plastic timing belt cover? to the right of the radiator hose).

Where are the spark plugs on a 2007 Toyota 4 cyl Camry. I removed the top cover and found holes with plastic liners which won't come out, but no spark plugs. Help needed.


Just follow the wires from the coil pack mounted on top, there are 4 of them, they will take you to the side of the motor where the spark plugs are hiding. Hope this helps.

How do you change spark plugs on a toyota yaris 2001


First you must remove the plastic cover from on top of the engine to access the ignition coils. The next step is to remove the ignition coils. To do this you must carefully disconnect the plug by holding down the plastic tab while pulling the plug off the coil. Then you must remove the small bolts holding the coils to the valve cover. Pull the coils straight out. To remove the spark plugs you will need a torque wrench, long extension and a self holding spark plug socket. All these can be bought at your local auto parts store. The spark plugs are removed by unscrewing them from the cylinder head and pulling them straight out. Installation is the reverse of removal. The spark plugs are tightened to 25 foot pounds of torque and the small bolts for the ignition coils are tightened to 10 foot pounds of torque.

Where are the spark plugs in a 1999 Toyota Carolla and how do I replace them?


Procedure:
  • 1. Remove the two 10 mm cap nuts on the top plastic housing over the engine
  • 2. Remove the two fasteners on the back of the housing and remove the plastic cover
  • 3. You will see four plastic blocks with four wire clips on each block. These blocks are individual coils for each spark plug.
  • 4. Use the small flat bladed screwdriver to carefully lift up on the tab that holds the electrical connector onto the block and slide the wire clip off the block.
  • 5. Remove the 10 mm bolt that holds the plastic block onto the engine. Use the needle pliers to firmly grasp the plastic screw and pull straight up to remove it 
  • 6. Loosen the 10 mm nut on end of the plastic rail that holds the wiring harness for the blocks so that the round plastic washer on the bottom of the block will not break when you pull off the block
  • 7. Carefully pull the plastic block out of the engine. There is a 4 inch tube attached to the block that extends into the engine to the spark plug. It will take some twisting and pulling but you must be careful not to catch the back part of the round plastic washer that you cannot see, on the bottom of the plastic wiring harness.
  • 8. The spark plug is at the bottom of the 4 inch hole.
  • 9. Use a 5/8 spark plug socket with a rubber collar on the 3/8" extension to remove the spark plug. The rubber collar will hold onto the spark plug as it is removed.
  • 10. The NGK website recommends making sure the spark plugs have the correct gap .044 but the spark plug box says not to adjust the gap because you might damage the needle point iridium tip. The new spark plug has a protective cardboard tube that is removed.
  • 11. Spark plugs can stick inside aluminum heads and break off when you try remove them, leaving only the threads of the plug inside the engine which will necessitate removing the head to remove broken spark plug. Putting antisiez on the threads of the new spark plug will prevent that in future spark plug changes
  • 12. Now comes an interesting choice. You can use the rubber tube over the neck of the spark plug to slowly drop it down the hole and hand tighten it or you can use the spark plug socket with the rubber collar. If you use the spark plug socket, the rubber collar will stick to the plug and you will pull off the extension, leaving the socket in the hole. A pair of long needle nose pliers will reach into the hole and remove the socket, but the rubber collar may remain on the plug and you will have to bend a piece of coat hanger with a short 90 degree tip to reach into the hole and pull out the rubber collar. The rubber collar is there to prevent you from cocking a regular 5/8" deep socket at an angle which will break off the neck of the spark plug, necessitating another 10 dollars and another trip to the auto parts store.
  • 13. After the spark plug is hand tight, give it 1/2 turn more.
  • 14. Replace the square block, being sure that the black silicone gasket on the bottom of the round plastic washer does not get bound up on the engine post where the 10 mm bolt goes. Tighten the bolt
  • 15. replace the electrical clip.
  • 16. Go to the next spark plug and repeat the procedure.
  • 17. After the last spark plug is done, be sure to re-tighten the 10 mm nut on the wiring harness rail
  • 18. Replace the plastic cover over the engine and you are done.
Good luck and hope this helps.

How to change plugs


Hello, and welcome to FIxYa.

To remove th plugs, you must first remove the plastic engine cover.

Next, with a 10 millimeter socket or wrench, remove the bolts that hold the coil-packs onto the cylinder head. After the bolts are out, a spark plug socket & ratchet, with a long extension are all that is needed. Make SURE you use TOYOTA plugs. Any other brand will make your car run poorly.

Have a 2006 Toyota Rav4, want to change the spark plug, asking for recommendation on which plu I should use, Also there are little plastic boxes with wire going to them over the plugs .. how do you remove...


Go to the dealer and get the recommended plugs. The litttle boxes are actually coil packs; carefully disconnect electrical connector, remove bolt(s), twist coil pack left and right and pull it off the plug. Unscrew plug with proper socket then remove. You may need a piece of vacuum hose to install the new ones. Put hose snugly over the plug and carefully start to thread it in. Also put on a little anti sieze compound on the plug's threading before installation. Ask for any other help.

Cant find the spaek plugs on a 2000 toyota corolla


on some cars you need to remove a plastic engine cover first.  And some cars have individual coils that sit on top of the spark plugs.  You thus need to remove these small coils to get to the spark plugs.

Spark Plugs


first open the hood and if you look at the engine theres is a black cover, there are two nuts on the bottom and you need a size 10mm socket if im not mistaken, take those off and on the top corner of the black cover there are two little plastic things that you just pop up with a flat screw driver. once all that is taken off pull the black cover up and put it aside. now you can see the 4 ignition coils because it dosent have spark plug wires. to get to the sparkplugs you need to take out the ignition coil. you need to remove the screw it is a 10mm socket i think and once you remove the screw disconect what ever its conected to and just give it a twist and pull it up and if you peak in the hole the spark plug will be right there.
