The number three plug can be removed with a  Swivel Spark plug socket as one unit. Once the Spark plug has loosen, remove the spark plug socket and remove by hand. Install by hand and spray the spark plug thread with WD-40 to make it easier for you to thread in to the heads. Once in use the swivel spark plug socket to torque, you can buy the spark plug socket with the swivel at Auto Zone or any large auto parts store, Good luck and keep me posted, All the spark plugs is best to changed through the wheel well and extension. Takes about 45 min to do all the spark plugs, 10 on the # 3  plug.

    The spark plug size with the swivel is 5/8 and make sure you have a long extension and spark plug boot pliers. It sounds like you have not replaced spark plugs on a blazer, here are some tips. Use platinum plug, there good for 100,000 miles. The best way to get to all the plugs are through the wheel well on both sides, just flip the splash guard up out of the way to get to the plugs and use a little anti seize on the the threads of the new plugs to make it easier to replace next time. Make sure when replacing the plugs the engine is cool and been running to ensure there are not thread damage to the heads, and replace the plugs one at a time to ensure you don't mix the firing order. Keep me posted if your going to do any more other then replacing the spark plugs be glad to help, and this is a good time to replace the fuel filter too and your going to need to by a quick fuel line release tool.

    Sorry about the spark plug braking, Should have told you that the plugs will break most of the time when removing from the top. If your a large person like some of the tech's your can remove the wheel to give you more room to work with, I personally can get by without removing the wheels and some prefer to just jack up the front end from the frame so you get just a bit more working room around the wheel well. Getting the #3 plug in and out is by hand after you loosen it, To tighten the plug you still have to thread it by hand till you can get the socket to fit between the shock tower and spark plug. Once your have the socket in to tighten the plug, attach the extension and torque. The other 5 spark plugs are also through the wheel well with the extension, the #3 plug is the only one that you have to do by hand then attach the socket and then extension. Keep me posted and keep up the good work.

How to remove top transmission bolts on a 2002 ford explorer

You will need two "special" tools. First a long (36" or so) extension, preferably 1/2" drive, and a swivel impact socket. All of the bolts around the bell housing are the same head size. I believe a 13mm. The way it is done is that you remove the transmission mount and let the trans hang down to give you more room, then use the long extension and swivel socket to reach the top 2 bolts.

How do you get the bac spark plugs changed does it take a special plug socket

No, you can gain accesss to these plug easily if you assemble the socket in the motor. ( ie. drop in the socket, add the extension, then snap on the ratchet) The removal of the tools is a bit tricky but it is possible. I generally use a pair of long needle nose pliers to pull out the socket.

Spark plug removal for 1996 Chevy S-10 Pick-up

It take's about 10 min to remove and replace that plug, You need a spark plug socket with a built in swivel and extension. All the plugs should be removed from going through the wheel well by just moving the slash guard out of the way. With the number #3 plug, (drivers side center) Your going to have to use the swivel socket to break loose the spark plug then remove by hand, there is not enough room for the socket and plug to be removed so it needs to be removed by hand and installed by hand too. Once the new plug is installed you can torque it by working the socket back on and then the extension. Good luck and hope this helps, all the other plug can be replaced through the wheel wel; without removing any other thing un less your a larger person and would like to remove the wheel for more room or just by jacking the S10 up but the front frame. Keep me posted and careful not to break a plug.

Changing spark plugs and spark plug wires on a 4 cyl. 1998 Jetta

the only way to remove the wires is to take the intake off.Its not that hard mine has 250,000 on it and it comes apart fine. But you need some special sockets and then it would even out if you paid somebody capable to do it for you. the plugs can be changed I use a swivel socket and a extension. The distributor should be fine I assume you meant the cap and rotor, that is easy but the clips that hold it down can be tricky to but back on. If it looks too difficult or scares you dont do it.

Changing plugs on 2004 xlt explorer

sometimes when your changing the plugs you have to use extensions, swivels in either 3/8 or 1/4 with an adaptor to use the 3/8 socket. or you can purchase a special spark plug socket that swivels on its own. and then there are those vehicles that you have to tilt the motor to get the back spark plugs out and in.

Changing spark Plugs

In reference to the Best Solution comment posted by "Apprentice" on October 6th, 2008, I add the following: This weekend I went through the ordeal of changing spark plugs and leads on a 2001 3.3 V6 Xterra owned by my younger son. Although some changes were relatively easy, there were those that had a degree of difficulty, in particular the 6th spark plug and lead at the rear of the engine between the block and the firewall. To simplify the removal and replacement of same, firstly remove the hood, this will give you addidtional space to maneuvre. Next remove the brackets that secure the A/C piping that runs across the upper area of the firewall. Also, release the brake lines from their firewall securing clips. You may even want to remove the brackets. Make it easy on yourself and remove any obstructing bracket, hoses etc that may inhibit access to the plug in question. Remember that the plug is below and inline with the 5th plug and the indentation in the firwewall. By removing all obstacles, you can now drop a swivel socket onto the plug head which is at a slight angle pointing towards the firewall. It is difficult to remove the plug lead but persevere and it will come off however, before you attempt to remove the plug, get a mirror down between the block and the firewall, shine a flashlight into it, and look to see if the ceramic on the plug has broken away (happened to me), this procedure will also help you locate the position of the plug. If present, make sure that you clean any debris out of the channel around the plug base. You really need someone with small hands and wrists to get down in there to remove any debris with a small straight edge screwdriver, the same goes for placing the swivel socket on the plug for removal. You will need a short extension connected to the socket and then a long extension with swivel to rise above the firewall. This is necessary to attach the socket wrench to the top of the final extension and give yourself adequate room to rotate. Remember, the angle is only slight and the extensions should be almost upright but favouring a slight angle towards the firewall. Be very careful when applying pressure to remove the plug and ensure the socket is perpendicular and not leaning to left or right, as you risk snapping off the plug terminal. Once the plug is out (only use a proper plug removal socket that will retain the plug securely within its body)remember the plughole position and angle, place the new plug into the secure socket and guide carefully towards the hole. Rotate the socket slightly clockwise and anti-clockwise and without pressure until you feel the plug seat down in the hole. Gently rotate the socket/plug clockwise into the thread. Once you know the plug is seated correctly and has connected with the blockhead thread, continue to rotate until tight but do not overtighten as you will risk snapping the plug off at the stem. Once in securely, those small hands come into play again to replace the plug lead, press downwards on both sides of the plug lead flange until the connector snaps in place over the plug stem, replace hoses and brackets, secure all pipelines and cables, clear all tools away from the top of the engine or around the compartment and crank the engine up before replacing the hood. If you have done everything correctly, the engine will fire up immediately. Once satisfied, and after patting yourself/ves on the back, replace the hood and test drive. You will find the difference amazing and the efforts worthwhile. Another tip, secure all extension rods, swivels and socket with electrical tape at the point of connection, this will ensure that if you have to tug hard at any time to get the tool out, it will not come apart. Important: Use only approved rating spark plugs that are designed to last 100,000 miles or you will not only be cahnging them again after 20,000 miles +/- and your vehicle will be once again a gas guzzler. approved ratings run between $2.50 and $9.50 per plug. Get the best, maybe expensive initially but, in the long run, you will benefit. Oh, yes, almost forgot. Advisable to disconnet the battery before you start working around the engine. Unlikely that the engine would kick over but best favour the side of caution!! David SE Florida Brit Property Consultant
