How to change spark plugs

Just a tight situation. Small arms help. Best access is from drivers side reaching down between firewall and engine. You will have to find and follow a plug wire one at a time, twist and pull off. ( careful wires if old will break off and a new set will be needed). Using same technique install the spark plug socket on the plug and appropriate extensions to get a good working clearance to loosen plug. Reinstall new plug in reverse order after checking gap. Plugs are in at an angles. You can see them if you really lean in and look down behind engine. It will just be a trial and error on gaining access and changing the plugs one at a time. A plug socket, a 2 inch extension and a 3/8 drive ratchet should do. Don't scrimp on cheap plugs. Good luck

You should still be able to get a spark plug socket on it. Unscrew it all the way until it is loose. I am assuming you have the engine where the spark plugs are recessed in the head and difficult to reach. What you need, once the remaining part of the plug is loose, is a very strong magnetic pickup tool that is long enough to reach the plug. Another option is to get a length of rubber hose just small enough to fit in the spark plug hole, but large enough to fit around the spark plug. Push the hose down over the spark plug. If it fits snug enough, you will be able to pull the plug out with the rubber hose. Good luck.

You don`t have to drop the engine but you have to climb up on it to reach down with your hands.It will be tight and you will come out with some scratches.The hardest part is usually getting the boots off the spark plugs.Sorry to say but there is no secret way.If there were I would have found it buy now.I work at a G.M. dealership.Going back on is the easy part.Let me know if you have anymore questions.Good luck.

1. Pull the hood release lever located under the dashboard.

2. Walk around to the front of the car, reach under the hood, find the latch and squeeze it. Open the hood.

3. Find the spark plugs, located in a row along one side of the engine (on an in-line four-cylinder engine) and attached to thick wires, called spark plug wires. Cars with V-shaped engines (which can have four, six or eight cylinders) will have spark plugs and spark plug wires on both sides of the engine.

4. Change one spark plug at a time, always putting the plug wire back on before changing the next spark plug.

5. Pull off one spark plug wire where it attaches to the plug. There is a little rubber boot at the plug end of the wire; pull on this part. Pulling higher up on the wire can damage the spark plug wire and cause it to separate.

6. Blow or wipe away any dirt or debris around the spark plug. You do not want anything to fall into the cylinder while the spark plug is out.

7. With the spark plug socket and a ratchet, remove the spark plug by turning it in a counterclockwise direction. You may need an extension for your ratchet if the spark plugs are deep-set or not directly accessible. Ratchets with flexible heads are especially helpful for hard-to-reach spark plugs.

8. Check the spark plug to make sure it needs replacing. A good spark plug should be lightly coated with greyish brown deposits. If heavy deposits are present, if the spark plug is black or if the electrode or core nose are damaged, the plug needs to be replaced.

Hope this is of help

it's can do, but you must have a good knowledge to do it, i will guide you how to do it, first get right spark plugs for your particular car, it's very impotent to get right spark plugs, otherwise it will get damaged engine, first remove top cover of engine, then very carefully remove spark plug lids from spark plug, keep in mind don't pull spark plug lids form wire it will brake easily, you must pull lids from plastic holder which is in side the head cover, after remove lids have good look inside holes before remove spark plugs, if you can see any dirty or dust inside hole between plug and housing you must remove that otherwise wen you remove spark plugs it will fall inside the combustion chamber, use high presser air to blow it, then you need right spark plug box for remove spark plug after remove the spark plugs get one spark plug to spear parts shop, and ask right one for that model, wise salesmen know how to find the right one, don't use any duplicate cheep spark plugs, even new spark plugs check the spark gaps all are the same, if you see any one deferant than outhers need to be correct the gap using piller Gage mus be use 33 lip on your piller Gage to set gap, then first your spark plug fix in to the plug box spanner and lowly insert in to the plug hole and tight it, don't let spark plug to fall in to the hole when you insert it, if it fall in, it can be change spark gap in your new plug, spark plug tighten tourque is 25nm, don't tight toomuch or don't let box spanner to angle when you tight, keep hold middle of hole when you tight it, it can crack ceramic part of spark plug, if one spark plug cracked it will make misfiring the engine, after replace all spark plugs clean lids hole using rags if its wet or oily, then install and press it in to the spark plug hole you can hear locking noise wen it get right. be careful don't mix up lids better keep mark all the lids if not numbers in lids, is this information helped you?

Engine off
Remove one spark plug wire / using correct size spark plug wrench with / rubber boot designed for spark plugs (deep well socket with rubber boot) remove (1) spark plug / gap new replacement spark plug to specs / install replacement spark plug by hand into head of engine /finger tight /using spark plug socket and rachet finish tighting spark plug / tighten just beyond snug being careful to not over tighten and breaking spark plug ..if in doubt about the proper tighting consult motor manual for torque specs. use torque specs in conjunction with appropiate torque wrench . Re-install removed spark plug wire ...proceed to remaining spark plugs doing one at a time until completed.

through the wheel wells

look under hood..you will see wires coming from distributor cap on top into your motor..if its an 8 cylinder there will be 4 in the back and 4 in the front.6 cylinder-3 in front 3 in back.get a 5/16 spark plug wrench and socket.you will need extension to reach back ones.if you bought new wires from parts store it will be even easier to find where plugs are located because you can compare the ones you bought and easier find the wires under the hood.the wire gets fatter as it goes into the motor.grab the fat part firmly and pull it off.boom theres your spark plugs.use your spark plug socket(5/16) with extension/ratchet and turn the plug until it comes out.do not break the plug or it will not come out.when you put a new one in screw it hand tight then 1 crank tight with the ratchet.when you change your wires do them one at a time as to avoid switching the wires up.on top of the distributor cap(where the wires lead to) there will be numbers as to what wire is for what cylinder...change plugs/wires 1 at a time dont take off more than 1 wire at a time!hope this helped!

put the car on rams and go from underneath to those 3 plugs

you can either reach them from underneath(its still tight too get too)
or take lose the the motor mount on the top passenger side and rock the engine forward!!!
