If you notice a symptom of engine trouble, you’ll want to bring it to the mechanic’s attention ASAP. By acting quickly, you’ll have the best chance to address the issue before it escalates and potentially leaves you stranded and needing more expensive repairs. At Auto Science, we provide expert engine repair in the greater Lewisville area. Here’s a look at five warning signs of an engine problem.

Check Engine Light

The check engine light on your dashboard serves as a warning system for a variety of potential issues. While the light may come on for minor reasons such as a loose gas cap, it can also indicate more serious problems. Common reasons the check engine light comes on include issues with oxygen sensors, MAF sensors, and catalytic converters. 

Strange Noises

There’s cause for concern if you notice sounds like knocking, rattling, hissing, or grinding. Knocking noises could signify issues with the engine's combustion process, while rattling might indicate loose components. Hissing could point to a leaking vacuum hose, and grinding noises might suggest problems with a water pump or starter motor. Abnormal sounds should be inspected promptly.

Overheating

Problems with your cooling system can lead to overheating, which can cause major engine problems. Signs of cooling system trouble include a spiking temperature gauge, coolant leaks, and steam emerging from under the hood. It’s important to promptly fix issues with cooling system parts such as water pumps, thermostats, radiators, and hoses. 

Discolored/Excessive Exhaust Smoke 

The smoke’s color can help with identifying the underlying problem. Blue smoke typically indicates burning oil, which could be due to worn piston rings or valve seals. White smoke might suggest coolant entering the combustion chamber, indicating a potential head gasket failure. Black smoke is often a sign of an overly rich fuel mixture.

Fluid Leaks

Leaking fluids under your vehicle should never be ignored. Engine oil leaks can result from worn gaskets, seals, or damaged oil pans, leading to low oil levels and potential engine damage. Coolant leaks may indicate a failing radiator, hose, or water pump, which can result in overheating and engine failure if left unaddressed. Fluid leaks should always be resolved ASAP.
