When you first notice a symptom of engine trouble, it’s important to alert the mechanic. If you delay, the issue may soon escalate and cause a breakdown and more costly repairs. At Hye-Tech Auto, we provide expert engine repair in the greater Covina, CA area. Here’s a look at five warning signs that it’s time for engine repair.

Warning Lights

One of the most straightforward indications of engine trouble is the illumination of the check engine light on your dashboard. This light is commonly triggered by issues with catalytic converters, spark plugs, oxygen sensors, and MAF sensors. An illuminated check engine light means you should promptly visit the shop for diagnostics.

Unusual Noises

Abnormal engine sounds should be investigated ASAP. Knocking sounds often indicate problems with the combustion process. Squealing noises can signal a belt problem. Grinding is often due to problems related to bearings. Paying attention to these noises and having your vehicle inspected can help prevent more serious damage.

Poor Performance

A noticeable decline in your vehicle’s performance is a clear sign of engine trouble. This can manifest as a lack of power, difficulty accelerating, or frequent stalling. Poor performance can stem from various issues, such as a clogged fuel filter or failing fuel pump, which restricts the flow of fuel to the engine. Ignition problems like worn spark plugs can cause misfires. 

Excessive/Discolored Exhaust Smoke

Different colors of exhaust smoke can point to different issues. Blue smoke suggests that oil is burning. White smoke commonly indicates coolant leaking internally, potentially from a blown head gasket. Black smoke is a sign that the engine is burning too much fuel.

Fluid Leaks

Engines rely on various fluids—including oil, coolant, and transmission fluid—to operate efficiently. Leaks of any of these fluids can lead to engine trouble. If you notice puddles of oil, coolant, or other fluids under your parked car, it’s a sign of a leak. Automotive fluid leaks can lead to very expensive repairs and should be addressed ASAP.
