How to change the current in a spark plug?

1 Locate wires for spark plugs and spark plugs. The cables are used to send current to the spark plugs of the ignition system. They can be found at the top of the engine. 2 Disconnect the wires from the spark plugs by pulling them off. They must leave immediately. Each cable has its own plug. If you mix the order, the engine will not work properly.

Where are the spark plugs on a car?

They must leave immediately. Each cable has its own plug. If you mix the order, the engine will not work properly. 3 Remove the plugs by unscrewing them.

What should I look for in a spark plug?

By examining the insulator firing nose color, an experienced engine tuner can determine a great deal about the engine’s overall operating condition. In general, a light tan/gray color tells you that the spark plug is operating at optimum temperature and that the engine is in good condition.

What should the firing end of a spark plug be?

If the firing end of a spark plug is brown or light gray, the condition can be judged to be good and the spark plug is functioning optimally. Although there are many different cases, if the insulation resistance between the center electrode and the shell is over 10 ohms, the engine can be started normally.

What to do if your spark plug is stuck?

If you discover the plug wire boot is ‘stuck’ to the spark plug try using spark plug wire pliers to aid in removal. The boot may need to be twisted back and forth to break the bond from the spark plug. Again, be careful. The metal terminal that connects to the spark plug inside the boot must be removed simultaneously with the boot to avoid damage.

How do you change a spark plug in a car?

Apply a small amount of plug wire grease to the plug wire boot (or COP boot) and re-install each plug wire or ignition coil. Be sure and connect the plug wires to the appropriate spark plug for each engine cylinder (refer to a firing order diagram if necessary). Re-install the coil hold down bolt (s).

How do you remove a cop spark plug?

COP designed coils attach directly to the spark plug end and use a long rubber insulator boot. Start the removal process by disconnecting the electrical connector from the ignition coil. Press down or pull up on the locking tab to make the connector release so it can be disconnected.

Where can I get a torque wrench for a spark plug?

Check your owner’s manual or the spark plug box. You will need a torque wrench, available at your local AutoZone. Apply a small amount of plug wire grease to the plug wire boot (or COP boot) and re-install each plug wire or ignition coil.
