For those who do not frequently change their vehicle, worries about engine performance and dependability may arise.

While there may be some significant engine issues, most can be prevented by regularly addressing maintenance needs. Our professional team at Rapto Part aims to discuss three typical engine problems that drivers may encounter and their underlying causes.

Common Engine Issue: Engine Fails to Start

One of the most common and anxiety-inducing issues with engines is when the car fails to start with a simple turn of the key.

This is a situation that almost every driver has encountered, and it can be quite unsettling. If the engine is making a clicking sound but not starting, it is likely a battery problem. However, if there is a crank but still no start, the issue may be related to fuel or ignition.

There are various common causes for engine failure to initiate, such as:

• Battery with low charge or fully discharged
• Battery cables that are corroded or not securely attached
• Failure of the starter motor relay
• Malfunction of the ignition switch
• Defective fuel pump
• Fuel filter that is clogged or dirty
• Not properly maintaining oil and filter changes
• Breakdown of the catalytic converter

The task of your motor oil is significant as it serves multiple purposes such as lubricating the engine, cooling its parts, maintaining its cleanliness, and preventing deposit buildup. However, over time even the highest quality oil will deteriorate.

As it ages, the oil will start to accumulate sludge and debris, which can harm your engine. To avoid this, it is important to regularly change the oil and filter, as recommended by the manufacturer. A general guideline is to have the oil and filter replaced every 3 months or after 3,000 miles to remove any contaminants and maintain the health of your engine.

The catalytic converter plays a crucial role in the exhaust system of your car. Its main function is to break down hazardous chemical emissions from the engine and redirect them away from the driver. While normal wear and tear is expected, the state of the catalytic converter can also be influenced by driving habits, road conditions, and the type of vehicle.

If you notice any unusual noises like rattling during acceleration or braking, or loud sounds while driving, it is advisable to schedule an inspection of the exhaust system.

The catalytic converter can fail due to rust or corrosion leading to leaks, or excessive carbon buildup which can cause internal blockages. To ensure the proper functioning of the entire exhaust system, it is recommended to have regular maintenance checks.

Issue with the Engine #2: Warning Light for Servicing Engine Soon

There are common causes for the activation of your “Service Engine Soon” light: Your car is fitted with a “Service Engine Soon” light which indicates the presence of any malfunction detected by the sensors linked to the emission, engine, or powertrain controls.

• Gas cap that is loose or missing
• Spark plugs or wires that are worn out or damaged
• Failure of the electronic control module
• Defective distributor or coil packs
• Issues with emissions control, such as the oxygen sensor
• Low quality fuel

Issue #3: Excessive Engine Heat

Although overheating engines are more frequently encountered during the warmer summer season, it is still possible for it to occur during the winter. Fortunately, most vehicles are equipped with temperature gauges or warning lights that can alert the driver if the engine is at risk of overheating. The most effective way to avoid engine overheating is by maintaining the coolant in good condition and ensuring regular servicing.

The main causes of overheating are typically related to the following issues:

• Malfunctioning or fractured thermostat
• Low coolant level or build-up of dirt
• Cooling fan that is not working
• Broken radiator hose
• Leakage of coolant internally or externally
• Faulty radiator cap
