Our Anaheim Mechanics Explain What To Do When Your Semi Truck’s Check Engine Light Comes On

When you're hauling freight over long distances, your semi truck is your lifeline. Breakdowns are not just inconvenient—they can cost you time, money, and potentially even safety. Knowing the signs your truck needs immediate roadside repairs can help prevent small problems from turning into major headaches. When you need 24/7 roadside assistance in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. Warning Lights Are Illuminated Your truck’s dashboard warning lights are there for a reason. If the check engine light, oil pressure warning, or brake warning lights come on, don’t ignore them. They’re indicators that something isn’t functioning properly and could worsen if not addressed promptly. Overheating Engine An overheating engine is a clear sign of trouble. This can be caused by coolant leaks, a faulty radiator, or a broken water pump. If you notice the temperature gauge climbing or see steam coming from the hood, pull over immediately to avoid causing severe engine damage. Loss of Power or Acceleration If your truck struggles to accelerate, feels sluggish, or isn’t delivering the power it should, it could indicate engine or transmission issues. These problems won’t fix themselves and could leave you stranded if ignored. Strange Noises or Vibrations Unusual noises—like knocking, grinding, or squealing—or vibrations coming from the engine, wheels, or drivetrain should not be ignored. These could point to failing components such as bearings, belts, or the transmission. Brake Issues Your brakes are critical for safety. If they feel spongy, make squealing noises, or require more pressure to engage, you could be dealing with worn brake pads, air system leaks, or other serious problems. Fluid Leaks Spotting puddles of oil, coolant, or transmission fluid under your truck is a sure sign that something’s wrong. Leaks can lead to overheating, engine damage, or loss of braking power. What to Do If you notice any of these signs, don’t wait—call for roadside assistance. At Orange County Fleet Services our professional mechanics can diagnose and address the problem on the spot or help tow your truck to a repair facility. Regular maintenance and prompt attention to issues can keep your semi truck running smoothly and reduce downtime. 24/7 Roadside Assistance in Orange County FSI powers Orange County Fleet Services’ mobile response team in collaboration with Richard Petty Garages.

Construction equipment is the backbone of any successful job site, and keeping it in good condition is essential for productivity and safety. Delaying repairs can lead to costly downtime, accidents, or even catastrophic breakdowns. Below, we discuss the warning signs that your construction equipment needs immediate attention. When you need construction equipment repair in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. Unusual Noises Heavy machinery is built to operate with specific sounds, so any grinding, squealing, or knocking noises are cause for concern. These sounds often indicate issues with internal components, such as worn-out gears, failing hydraulics, or loose belts. Ignoring these warning signs can result in more significant and expensive damage down the line. Fluid Leaks Construction equipment relies on various fluids, including hydraulic oil, coolant, and transmission fluid, to function correctly. Puddles or visible leaks under your machines should never be ignored. Fluid loss can cause overheating, poor performance, or equipment failure. Regular inspections can catch leaks early. Excessive Smoke or Exhaust If you notice excessive smoke coming from the exhaust, it could signal engine trouble. Blue smoke indicates oil burning, white smoke suggests coolant leaks, and black smoke points to a fuel or combustion issue. Decreased Performance When machinery begins to operate sluggishly, struggles to lift loads, or moves more slowly, it’s a clear sign something isn’t right. This could be due to hydraulic issues, engine wear, or transmission problems. Ignoring decreased performance delays projects and can cause irreversible damage. Warning Lights or Error Codes Modern construction equipment is equipped with onboard diagnostics that alert operators to malfunctions. Ignoring warning lights or error codes can exacerbate issues. Always consult the equipment manual or call a repair technician to address the problem immediately.

Tackling an oil leak in your semi truck promptly can spare you costly repairs and frustrating downtime. These leaks can stem from a range of causes—some minor, others more severe. We dive into the key culprits behind oil leaks in semi-trucks and why swift action is critical to keeping your rig running smoothly. When you need oil leak repair in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. Worn or Damaged Gaskets Gaskets are crucial for preventing oil leaks and sealing engine parts. Over time, these gaskets may wear out or deteriorate due to the constant pressure and high temperatures. Head gaskets, oil pan gaskets, and valve cover gaskets are common culprits. If the gasket has deteriorated and oil starts to leak through the seal, there can be noticeable drips underneath your truck. Frequent maintenance helps spot gasket issues early on before they result in significant leaks. Loose or Damaged Oil Pan The oil pan contains the oil that lubricates your engine. If road debris or difficult driving conditions cause the oil pan to become loose, broken, or dented, oil may start to leak from the region. A malfunctioning drain plug or a failed oil pan seal could be the source of the leak. Check the oil pan during regular maintenance to avoid these problems. Faulty Oil Filter An obstructive or improperly positioned oil filter may be the source of oil leaks. When an oil filter is worn out or improperly sealed, oil may seep from the filter housing. This is often a straightforward fix, but if ignored, it can eventually lead to decreased oil levels and issues with engine performance. Crankshaft or Camshaft Seals Keeping oil in the engine where it belongs is the goal of the crankshaft and camshaft seals. But with time, these seals may fail due to heat and engine wear, which could lead to oil leaks from the front or rear of the engine. When these seals break, you'll likely notice oil leaking from the front or rear of the truck. This needs to be remedied immediately to prevent further engine damage. Overfilled Oil Reservoir Oil may leak out of gaskets and seals that are otherwise in good condition if your truck's oil reservoir is overfilled because the system may suffer high pressure. To avoid unnecessary leaks caused by too much oil in the system, always ensure the oil level is within the range recommended by the manufacturer.

Proper battery care is an essential part of fleet maintenance, playing a major role in vehicle reliability and overall efficiency. When managing a fleet of delivery trucks, service vehicles, or heavy machinery, keeping the batteries in good condition is essential. Below, we discuss why battery care should be a priority in your fleet maintenance routine. When you need to replace a battery in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. Preventing Unexpected Breakdowns Fleet vehicles are often in constant use, with high demands placed on their electrical systems. A weak or failing battery is one of the most common causes of vehicle breakdowns. Regular battery checks can help identify issues before they become major problems, reducing the risk of a vehicle being sidelined unexpectedly. A dead battery during a delivery or service call can cause delays, impacting your business’s productivity and customer satisfaction. Extending Battery Life By implementing routine battery maintenance, you can significantly extend the lifespan of your fleet’s batteries. Checking for corrosion, cleaning terminals, and ensuring batteries are securely fastened can prevent damage. Regular testing for voltage levels and ensuring the charging system is functioning properly also helps prevent premature battery failure. Keeping batteries in good condition reduces the frequency of replacements, saving costs over time. Maximizing Fuel Efficiency Batteries in poor condition can strain the vehicle’s alternator, causing it to work harder to keep the battery charged. This extra load on the alternator can negatively impact fuel efficiency. In a fleet where fuel costs are a significant operational expense, ensuring your batteries are in top condition can lead to savings by helping your vehicles run more efficiently. Supporting Modern Electrical Systems Fleet vehicles today are often equipped with complex electrical systems, from GPS and telematics to advanced safety features. These systems rely heavily on a well-functioning battery. Neglecting battery care can lead to electrical malfunctions, which can impair vehicle performance and safety. Keeping the batteries properly maintained ensures that all the onboard systems function as they should, keeping the fleet running smoothly.

Fuel is one of the largest expenses for semi truck drivers, but careful driving practices and well-thought-out decisions can increase fuel efficiency and save money at the pump. Below, We review some useful advice for cutting fuel costs on your semi truck. When your semi truck needs maintenance or repairs in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. Maintain Steady Speeds Maintaining a steady speed while driving is essential for fuel efficiency. Your truck will use more gasoline if you accelerate quickly and brake forcefully. When driving on a highway, using cruise control helps you keep a consistent speed and save fuel. Monitor Tire Pressure When tires are underinflated, they have higher rolling resistance, which increases engine effort and fuel consumption. To increase fuel efficiency and prolong tire life, regularly check and maintain proper tire pressure. Reduce Idle Time Allowing your truck to idle uses a lot of fuel. Reducing idle time can result in large savings, particularly during breaks or when loading and unloading. Auxiliary power units (APUs), which provide electricity and climate control without idling, are a common feature in semis. Invest in Aerodynamic Upgrades Trucks with aerodynamic features like tail devices, roof fairings, and side skirts can cut through the air more effectively by lowering wind resistance. Although there may be initial costs associated with these adjustments, over time they can result in significant fuel savings. Use High-Quality Fuel Lower-grade fuels can lead to poor engine performance and decreased fuel economy, despite the allure of cheaper fuel. Over time, engines running on high-quality diesel save gasoline because they operate more smoothly and efficiently. Get Regular Oil Changes Maintaining your semi truck's fuel economy requires routine oil changes. New oil keeps the engine operating smoothly by lowering friction between moving parts, which increases engine and fuel efficiency. The truck may use more fuel because of increased engine wear and decreased performance brought on by outdated or dirty oil. Maintaining a regular oil change schedule will help you save money on fuel and maintenance over time by extending the engine's lifespan and increasing fuel efficiency.

Keeping your semi truck running strong for years to come requires a combination of regular maintenance, smart driving habits, and attention to detail. Your truck is more than just a vehicle; it's the backbone of your livelihood, and taking care of it will ensure that it stays on the road. When it’s time to schedule maintenance services for your semi in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. Prioritize Regular Maintenance Routine maintenance is the foundation of a healthy semi truck. This includes regular oil changes, checking and replacing filters, and ensuring that all fluids are topped off. Pay special attention to your truck's engine, transmission, and brakes, as these components are vital to its overall performance. Scheduling regular inspections with a trusted mechanic can help catch small issues before they become major problems, saving you time and money in the long run. Keep an Eye on Tires Tires are one of the most critical aspects of your truck's performance and safety. Regularly inspect your tires for wear and tear, and ensure they are properly inflated according to the manufacturer's specifications. Uneven tire wear can be a sign of alignment issues or suspension problems, both of which should be addressed promptly to avoid more significant damage. Rotating your tires regularly will also help extend their lifespan and maintain a smooth ride. Monitor Your Driving Habits How you drive can have a significant impact on your truck’s longevity. Avoid harsh braking, rapid acceleration, and excessive idling, as these can put unnecessary strain on the engine and other critical components. Smooth and steady driving, along with adhering to speed limits, can reduce wear and tear, improve fuel efficiency, and keep your truck running smoothly for years to come. Don’t Neglect the Undercarriage The undercarriage is often overlooked, but it's essential to keep your truck clean and free from rust and corrosion. Regularly washing the undercarriage, especially after driving on salted roads, can prevent rust from taking hold. Applying a protective coating can also help shield the undercarriage from the elements. Stay on Top of Minor Repairs Don’t ignore the small things. A minor leak, strange noise, or dashboard warning light might not seem urgent, but addressing these issues promptly can prevent them from escalating into more serious and costly repairs. Being proactive with repairs ensures that your truck remains in peak condition and avoids unexpected breakdowns.

Getting your tractor ready for the summer months in Anaheim is important for maintaining its performance and longevity. As the temperatures rise, your tractor will face different demands, making proper preparation necessary. We explore the key tasks you should perform to prepare your tractor for the summer heat. When your tractor or other farm equipment needs repairs or maintenance in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. Check and Change the Oil Regular oil changes are necessary to keep your engine running smoothly. Before the summer season starts, check the oil level and condition. If the oil is dirty or hasn't been changed since the previous season, it's time to replace it. To get the best results, use high-quality oil recommended by the manufacturer. Inspect and Clean the Air Filter Dirt and debris can clog air filters over time, reducing airflow and engine performance. To keep your tractor running smoothly, check the air filter regularly and clean or replace it as needed. Examine the Tires Inspect your tractor's tires for signs of wear, damage, or low pressure. To avoid problems while driving, pump the tires to the recommended pressures and replace any that are significantly worn or damaged. Check the Battery Clean any rusted battery terminals. Make sure the battery is correctly placed and charged. To avoid unexpected downtime, replace the battery if it is outdated or no longer holds a charge. Inspect Belts and Hoses Regularly inspect belts and hoses for signs of wear, cracking, and fraying. Replace any damaged or worn belts and hoses to avoid costly repairs and downtime. Lubricate Moving Parts Lubrication effectively reduces friction and wear in your tractor's moving parts. Check the manufacturer's instructions for recommended lubrication locations and timings. Apply grease or oil as needed to keep components including joints, bearings, and gears functioning smoothly. Clean and Inspect the Cooling System Summer temperatures can put an extra burden on your tractor's cooling system. Maintain a clean and debris-free radiator for optimal cooling. Check the coolant level and top off as needed. Inspect hoses and connectors for leaks or damage, and repair or replace them as needed. Test the Brakes and Steering When operating heavy machinery, safety comes first. Check your tractor's brakes and steering to ensure they are working properly. If you notice any problems, fix them immediately to guarantee safe and reliable operation.

To extend the life of your semi truck’s engine, the air filter needs to be maintained. A clean air filter allows the proper mixture of fuel and air needed for combustion, which makes the engine function smoothly. We discuss how often to clean the air filter below. When you need semi truck services in Anaheim, CA, or the surrounding areas, give Orange County Fleet Services a call. What Are the Benefits of a Clean Air Filter? By supplying the engine with the ideal amount of air for efficient combustion, a clean air filter helps increase fuel efficiency and reduce pollutants. Regular cleaning or air filter replacement prolongs engine life and reduces the need for costly repairs by keeping dirt and debris out of the engine. How Often Do You Need To Clean the Air Filter? The number of miles and the type of driving you do influence how frequently you should clean the air filter. In general, we recommend performing an annual or every 15,000–30,000 mile air filter cleaning and check. If you frequently travel in rough or dusty conditions, more frequent maintenance might be necessary. Signs of a Dirty Filter Reduced engine performance, which includes weaker power and sluggish acceleration, is a common sign of a dirty air filter. Furthermore, you might notice a drop in fuel economy that requires more frequent refueling. A dirty or clogged filter, strange engine noises, or a check engine light all indicate that the air filter needs to be changed. If your truck's exhaust is emitting black smoke, it can be a sign that a dirty filter is limiting airflow.
