Maintaining a smoothly running engine is vital for achieving peak performance, maximizing fuel efficiency, and ensuring safety. Our roadworthy certificate center goes beyond issuing compliance certificates; we conduct detailed diagnostics to detect early signs of engine problems. Regular maintenance, along with car professional repair services, keeps your vehicle dependable and extends its operational life. In this post, we will highlight seven prevalent engine problems and provide useful tips to avert them, enabling you to prevent costly breakdowns and keep your car in prime condition.
1. Engine Overheating
Symptoms: Increasing temperature reading, steam escaping from beneath the hood, and the heater emitting cold air.
Causes: Insufficient coolant, malfunctioning thermostat, obstructed radiator, and problems with the water pump.
Prevention:
- Continuously monitor for any oil leaks in the areas of gaskets and seals.
- It is important to replace oil and filters on time; do not allow long intervals that could cause sludge formation.
- Select the suitable oil grade for optimal viscosity performance.
- Monitor oil pressure and flow during each service to detect pump wear early; combined with our professional automotive repair services, this can help prevent extensive engine damage.
2. Oil Sludge and Contamination
Symptoms: Audible signals including knocking, oil alert lights, and erratic idling.
Causes: Deferred oil changes, inferior oil, and short drives that do not properly warm up the engine.
Prevention:
- Replace the oil and filter for the engine following the intervals advised by the manufacturer.
- Select top-tier oil that is compatible with your vehicle’s specifications to mitigate deterioration due to heat.
- Periodically alternate between quick drives and highway travel to decrease moisture buildup.
- At each service appointment, check the area beneath the oil filler cap for substantial dark accumulation.
3. Low Oil Pressure
Symptoms: Indicators like the oil pressure warning light, strange engine sounds such as ticking or knocking, and a decrease in power can point to potential problems.
Causes: Likely reasons might be oil leaks, an obstructed oil filter, a failing oil pump, or oil that has lost its effectiveness.
Prevention:
- Systematically examine for potential oil leaks around seals and gaskets.
- It is vital to replace oil and filters on time, do not allow long intervals that could result in sludge formation.
- Select the suitable oil grade for optimal viscosity performance.
- Monitor oil pressure and flow during all services to detect pump wear promptly; combined with our professional automotive repair services, this can help prevent extensive engine damage.
4. Engine Misfires and Rough Idling
Symptoms: Noticing vibrations while stationary, a reduction in acceleration, and the engine warning light illuminating on the dashboard.
Causes: Possible complications may arise from malfunctioning spark plugs, clogged fuel injectors, failures in the ignition coil, or leaks in the vacuum system.
Prevention:
- Replace spark plugs at intervals ranging from 30,000 to 60,000 kilometers, depending on their specific type and how they are used.
- To support proper airflow, make it a habit to regularly clean or swap out air filters.
- Regularly employ fuel injector cleaning agents to eliminate buildup.
- Our extensive service range includes engine repairs, windscreen replacements, and other bodywork services, ensuring a seamless and convenient solution for our customers.
5. Timing Belt or Chain Failure
Symptoms: The engine does not engage and emits pronounced slapping or rattling noises, while oil is leaking close to the timing cover.
Causes: This could result from a degraded belt or chain, alignment issues, or a defective tensioner.
Prevention:
- Adhering to the recommended replacement intervals, which usually fall between 100,000 and 160,000 kilometers, is vital.
- It is essential to examine the tensioners and pulleys for their proper functioning at each service visit.
- Going to a trusted roadworthy certification center can confirm that your drivebelt system adheres to safety regulations, helping to avoid possible engine malfunctions.
6. Coolant Leaks and Corrosion
Symptoms: Water accumulation beneath the vehicle, engine overheating, coolant level alert, corroded coolant reservoir.
Causes: Defective radiator or hoses, rusted heater core, broken water pump gasket.
Prevention:
- Carry out visual assessments of hoses, radiator fins, and clamps at every oil change.
- Install new hoses in place of any old or deteriorating ones to eliminate the risk of cracking.
- Adopt the manufacturer’s suggested coolant to decrease the likelihood of corrosion.
- Should you detect a chip in your windshield, it is crucial to respond quickly—our windshield replacement service uses state-of-the-art resins to reinforce durability and clarity.
7. Dirty or Clogged Air Filter
Symptoms: Decreased acceleration, low fuel efficiency, dark exhaust emissions.
Causes: Collection of dust, pollen, and debris in the intake system.
Prevention:
- Change the air filter every 15,000 kilometers, or more often if driving in dusty environments.
- Review the filter housing for signs of insect nests or debris that may not be captured by the filter.
- For improved engine performance and passenger comfort, synchronizing the replacement of air filters with cabin air filters is recommended.
