Changing your Spark Plugs
It’s said that for optimum performance you should be changing your car’s spark plugs every 30,000 miles. If you’re unsure on what you need to do, but you’re determined to carry out the work yourself, and then follow our simple steps.
First locate the spark plugs. There will be 4-8 wires leading to the engine compartment. Only remove these when the engine is cool, and once removed simply measure the gap of the spark plug, perhaps by using a fine gap checker. You’ll need to chekc your manual to see the size of the gap you require.
You must then check the existing plugs for any signs of wear, as they may not all need replacing. Then you should clean inside the plug, and the surrounding area, while perhaps cleaning up the tip of the spark plug if there is any wear or rust. Then you should lubricate the plug and reinsert them, tightening them with your ratchet.
