Your vehicle is made up of hundreds of parts that must all work together to keep you moving safely and efficiently on the road. When just one of those parts begins to wear down or breaks, it can cause a ripple effect of issues.
Regular check-ups and knowing the warning signs of a potential problem are your best tools to avoid a roadside breakdown and costly repairs. You know to check fluid levels and tire pressure, get regular oil changes and maintain good alignment, so what else should you keep an eye on?
If your vehicle is nearing the 60,000 mile mark, it’s time to take a deeper dive inside your engine and look at critical wear items such as the timing belt if equipped, spark plugs, air filters, fuel filters and more.
Engines equipped with a timing belt are typically due for service around 60k-100k miles, timing belts are responsible for synchronizing the rotation of the crankshaft and camshaft(s) to ensure the engine valves open and close at the right time. Without proper maintenance, your timing belt could break and cause catastrophic damage inside the engine, requiring the replacement of new valves, pistons and other major engine parts.
A mid-drive failure could lead to a loss of engine power, as well as critical systems like power-assisted steering and braking. Reduced power while climbing a hill, excessive smoke, engine shaking while running, or a flashing check engine light are all signs of an engine performance issue, often caused by component failure. Some parts, such as spark plugs, timing belts, and valve clearance, may not show signs of wear until they fail completely. That’s why following the manufacturer’s recommended service intervals is essential. Servicing your vehicle at Japanese Auto Service ensures a thorough inspection, so any necessary maintenance items recommended by the manufacturer can be addressed before they become major issues.
Stay safe on the road and avoid those costly repairs by spotting the signs of low engine performance before it’s too late:
Excess noise from engine
Engine misfiring
Oil leaks
Vehicle struggles to start
Rough or inconsistent idling
Check engine light / flashing check engine light
Smoking from tail pipe
