Replace sparkplugs How to replace sparkplugs.

Hi Gary!

If you got a CAR and not a truck, there are a few things you need to pay attention to when replacing spark plugs.

You need to make sure your spark plugs are the issue for whatever the problem is.
Take a 16mm SPARKPLUGS spanner (it's a special sort of tool that you buy in the shop, unless you have it, don't bother to try with anything else, or your could do some damage), unplug one of the cables attached to one of the sparkplugs (make sure you don't unplug more that one, so you won't mess the order), take your magic tool (sparkplug socket spanner or whatever it is called) fit it on top of the sparkplug, (listen for the clicking) and then twist it left until the sparkplug is out.

Have a look to your sparkplug, and see if there is any carbon on it (if it's black, it has to be replaced/sandpapered)

repeat the operation to the other (alledgedly 3) sparkplugs, naking sure you DO NOT MESS UP the order of the cables that connect to the sparkplugs.

If finally you've decided it is time to replace the sparkplugs, under NO circumstances, replace less than ALL of them. (unless you replace them on the car of someone you don't like)

i don't know

Check ignition lead - ignition cap and sparkplug. look signs of wear or cuts on the lead. The cap should be tight on the sparkplug. The sparkplug must be free of cracks and not unusually blacked out. Replace if in doubt.

Quick test is to open the hood in the dark. Let someone start the car and look for blue sparks around the lead and sparkplug cap. Be careful - keep away from moving parts.

This all depends on the year and the rtype of sparkplug being used, for example a regular sparkplug i would replace at about 40,000 miles but then you have paltinum and double platinum sparkplugs that i have seen go 100,000 miles but i would replace those at about 70-80,000 miles. good day.

Hello, Depending on the Year of the car, the cars that had a sparkplug with a remote coil, you could have a bad sparkplug wire or a bad coil-pack or a bad sparkplug. For newer cars, the coil is attached to the sparkplug directly on top.

For those newer designs, the coil would need to be tested for that cylinder. Using an Ohmmeter, with 1 lead on top and the other on the tip which touches the sparkplug, it is a 10,000Ohm resistance.

Accessing the sparkplug coil is different for several engines. You may have to remove the Intake manifold to reach the coil and you may need to remove part of the fuel rail to remove the Intake manifold. Switching out a plug or coil is easy once you can get to it.

You can have your scans done free at Autozone, Oreillys, or Advance autoparts and they will clear the problem codes once you replace parts. I hope this Solution is very helpful to you.

Open the hood to access the engine compartment. Locate the sparkplugs sitting to the side of the motor. Six wires run to the motor, three on each side.

Twist the rubber boot and pull away from the sparkplugs. This will expose the sparkplug.

Unbolt the sparkplug with a socket wrench. Use a 5/8-inch deep-well socket attached to the socket wrench.

Pull the sparkplug away from the motor. Discard the sparkplug.

Screw the sparkplug into the motor by hand. Make sure it is hand-tight.

Tighten the sparkplug with the socket wrench, using the deep-well sparkplug socket.

Click the wire to the sparkplug wire to the end of the sparkplug. Gently pull the wire to ensure it clicks into place.

Repeat the procedure for the remaining five sparkplugs. Change each sparkplug one at a time.

With you hood open and you are standing in front of the car sparkplug wires need to be removed,i suggest you remove them one at a time, under each wire the sparkplug is threaded into the cylinder head,using a 5/8 sparkplug socket remove the sparkplug and replace it with new properly gapped sparkplug.Note:if you remove all sparkplug wires at once the factory wires are generally numbered 1 2 3 4 the sparkplug closesed to the passenger fender is #1 and the one clossesed to the driver's fender is #4.Standing in front of vehicle the PCV Valve is located between #3 and #4 on the backside(intake side) of the engine fitted down into a rubber hose

Here are some instructions:

1. open hood
2. disconect battery
3. remove sparkplugs cable
3. use a torque ranch to remove sparkplugs (turn to left)
4. replace with new sparkplugs
5. connect cables
6. connect battery

Start car and check for missfires

Good luck!!!

the catalytic converter maybe pluged .

#3 sparkplug is not firing at peak performance.
The engine block sparkplug hole had to be re-threaded in order to accept an adapter for the replacement spark plug. The sparkplug is sitting "higher" in the cylinder than the others (not as efficient).
It may even be a different sparkplug altogether in order to accommodate the adapter.

Add a silicone insulator gel (AutoZone $2) inside both boot ends of the sparkplug wires and re-seat them all.
