How do you change the spark plugs on a GMC Yukon?

Place the spark plug wire onto the new plug and push it in until you feel it snap into place. Repeat the process on the next spark plug until you change them all. Inspect the spark plug wires closely when you change each plug. If you find any problems, such as cracking, replace the entire set.

How long are spark plugs good for in a Yukon?

In fact, while most manufacturers state that your spark plugs are good for 40,000 miles or more, you should never wait that long in between changing them. They do not cost that much, and the fresh plugs will keep your Yukon operating efficiently. It does not take that long to change them.

How do you change a spark plug in a car?

Discard the old plug. Put the new plug into the cylinder head and tighten it snugly. Be careful not to cross-thread the spark plug in the cylinder head or you will damage it. Place the spark plug wire onto the new plug and push it in until you feel it snap into place. Repeat the process on the next spark plug until you change them all.

Why do I need to change my spark plug wires?

However, there are other factors that can play a role in the timing. Damage: It’s possible for spark plug wires to be damaged. If the insulation is compromised, or there’s an internal break, you’ll need to replace your wires even if it’s not yet time.

How do you remove a spark plug wire?

Just remove the plug wire without damaging it, and use the proper socket, extension, and U-joint to remove and install the plugs. @Groy I would also budget for a spark plug wire set and the spark plug heat shields.

When to change spark plug wires, Ricks free auto repair?

The actual value you get from testing each wire isn’t as important as the consistency between the wires. So if you test a 3-ft spark plug wire and get a reading of 10,000 ohms, all other 3-ft. wires should test the same. So if you find a wire with significantly less or more resistance, you know that it’s defective.

Do you have to change the spark plug wire?

If your vehicle came with MAG wires, you MUST replace them with the same type. The third type of spark plug wire is the fixed resistor style. They’re made with a steel or copper core and a resistor located in the spark plug boot. If you car came with them, replace them with the same style.

Do you need an ohmmeter for spark plugs?

You’ll need an ohmmeter for this, and you’ll need to know what the wires’ original resistance was. Test each wire and look for resistance levels higher than when originally installed, as well as higher resistance in individual wires (which indicates a failed wire).
