How often should the spark plugs be replaced in the new Crown?
2 Answers
The spark plugs in the new Crown should be replaced every 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system, responsible for introducing high-voltage electricity into the combustion chamber and creating a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. The dimensions of the new Crown are 4910mm in length, 1800mm in width, and 1455mm in height, with a wheelbase of 2920mm. The Crown is equipped with three engine options: 2.5L, 3.0L, and 4.3L. The first two are V6 24-valve designs, while the 4.3L engine is a V8. The engines feature the Dual VVTi system, which intelligently varies the timing of both intake and exhaust valves, significantly improving the engine's air intake efficiency, fuel economy, and power performance, resulting in stronger horsepower. The chassis is equipped with a four-wheel fully independent suspension system.
The replacement interval for Toyota Crown spark plugs should be determined based on the specific recommendations in the manual. Generally, most models recommend replacement every approximately 60,000 kilometers, but the type of spark plug is also crucial. Platinum or iridium spark plugs can last up to 100,000 kilometers, while standard copper ones might need replacement as early as 40,000 kilometers. Worn-out spark plugs can lead to common issues like difficulty starting the engine or sudden increases in fuel consumption—I've encountered many such cases when helping friends inspect their cars. Delaying replacement may also contribute to engine wear. It's best to have the technician check the electrode gap during routine maintenance; if it's too wide, it's time for a replacement. The replacement process is actually straightforward and costs just a few dozen dollars. Don't wait until they fail to address the issue, as that could result in higher repair costs and potentially compromise driving safety. Regular maintenance is a good habit for extending your vehicle's lifespan.
