Does Your Ford Need a New Catalytic Converter?

Catalytic converters were invented as a means to save the environment from pollutants, keep our cities free of smog, and ensure our air stays fresh and breathable. Not only is this device legally mandated to be included in your fuel system, but it can also benefit you through improved fuel economy and increased horsepower. If you suspect your converter is going out, this list will offer you some hints to decide if it's time for an update.

1. Loud Noise Beneath the Vehicle

The purpose of the converter is to trap harmful gases from your exhaust and use a catalyst, usually a precious metal, to change the molecule into a harmless form. Along with the catalyst, this is accomplished through a ceramic base and layers of mesh. When degraded, the mesh can fall apart and bounce around within the metal casing, resulting in a rattling sound. This noise will become especially apparent as the engine turns over.

If the noise is exceptionally loud you may have lost your converter completely. A situation like this may be accompanied by a sulfur smell and will sound like a roar when you accelerate the engine.

2. The Engine Light Turns On

Having the engine light turn on can mean a variety of issues, and a damaged converter may be one of them. When the device's film becomes clogged, air is unable to pass through the engine as it should. This results in an incorrect mixture of fuel and air, which may be picked up by your ratio and oxygen sensor. A mechanic should be able to run the error codes and let you know if your engine light relates to your airflow.
 

3. Decreased Performance

Engines are designed to run with an ideal mixture of air to fuel, and when the converter is clogged or damaged that ratio will be incorrectly balanced. When you attempt to accelerate, gas will be added to the engine but have no air to actually burn with it, resulting in more trips to the pump and more money wasted.

These days converters can improve your fuel economy and horsepower beyond serving their usual function. A high-flow converter contains more of the precious material than the basic version as well as a wider mesh film, resulting in faster conversion of the pollutants with an increase in the volume of air your engine can pass.

If you want to get the most out of your vehicle you're going to want a converter that is functioning at its best. Keeping this device clean and operational ensures the safety of everyone on the road. Visit Crain Ford of Jacksonville and be certain you are getting the best fuel economy and horsepower from your engine.

How to Tell When Your Ford Needs a Radiator Repair

Is Ford's engine hotter than usual? Although there are several causes for the increased heat, the most typical is a faulty radiator. Do you want to maintain your car's peak performance? Watch out for the following signs to know if you need a radiator repair before consulting with your Ford dealer in Jacksonville, AR. Your Engine Has Temperatures That Are Too High When your engine's temperatures rise, your vehicle will gradually overheat. When this happens, check your Ford's temperature device on the dashboard tool panel to determine if its meter has risen above the middle. Typically, high temperatures imply issues with your radiator. Inspect the radiator immediately before the temperature rises further. At best, you may need more coolant. Still, don't risk damaging your engine permanently by driving the overheated car. Seek expert inspection. Your Engine Releases White Smoke When an abnormal amount of white smoke emanates from your car's engine, know there's an issue worth addressing. In general, white smoke may indicate leakage in the internal coolant system. This arises when your engine burns up your coolant, which exits through the exhaust. Although the issue might not cause alarm, have your dealer inspect the white smoke's origin to be safe. Your Vehicle Has a Poor Heating System Do you feel like your vehicle heater's system is compromised? Is your heater not efficient? If yes, you may have an issue with your radiator. Hot coolant fluid keeps your car heater power. When your radiator is compromised, it won't heat the coolant fluid sufficiently. Apart from experiencing excess heat, you'll also experience too much cold, which is more apparent during the cold season. Your Coolant Leaks on the Ground One of the most visible signs of a faulty radiator is having a coolant leakage underneath your vehicle. Are there drips or puddles of a bright green substance underneath it? This generally implies a leak in the radiator, which can cause permanent damage to your engine. Because the source of the leak could be your hose or other parts of your vehicle's cooling system, you shouldn't diagnose the problem yourself. We can help you identify whether your radiator is cracked and needs a replacement by conducting a pressure test. Your Radiator Discolors and Rusts When exposed to moisture and fluids for a long time, your radiator will start to look rusty because it's made up of metal. So, watch out for color changes. In some cases, the rust might be accompanied by sludge. Note that rust in your radiator can permanently damage your vehicle. The only way to get rid of it is by having your dealer flush your entire system. We not only specialize in flushing but also in replacing the corroded parts in your system. We are well aware that a simple flush is not adequate to fix the problem. If you've spotted any one of these signs, don't hesitate. Seek expert assessment today. Stop by Crain Ford of Jacksonville today and have your vehicle assessed.

What Happens During a Routine Ford Transmission Service?

Automobiles are designed to carry the driver, passengers, and cargo from a starting point to their intended destination. We can argue about which vehicle components are most vital, but to adjust speed to navigate safely through traffic, you'll need a transmission. Like other systems, transmissions require periodic maintenance. As your Ford dealer in Jacksonville, AR, Crain is the ideal place to have that maintenance done. What does Ford transmission service entail? Let us lay it out for you. How Often Should You Visit Your Jacksonville, AR Ford Dealer to Service Your Car or Truck's Transmission? Transmissions typically don't require service as frequently as engine, radiator, and brake systems. The usual range for changing transmission fluids and filters lies between 30,000 and 60,000 miles, with greater frequency recommended for vehicles used for towing. Check your owner's manual for a more precise figure for your particular vehicle. If you can't find your manual, you can usually obtain a copy online. Owners' manuals for most makes, models, and years can be downloaded at no charge. What Is the Difference Between a Transmission Fluid Change and Flush? Transmission flushes are more thorough than regular fluid changes, replacing the fluids in the lines and other portions of the transmission, as well as in the pan. Like engine oil, transmission fluid cools and lubricates the gears and other moving parts in your transmission. It often contains additives to keep everything clean. Over time and extensive use, dirt accumulates in the fluid. If it is dark and murky, rather than the normal red or green, a fluid change won't be sufficient. A transmission flush will be required. Does It Matter Whether Your Vehicle Has an Automatic or Manual Transmission? Automatic and manual transmissions differ in two key manners. Manual transmissions experience higher degrees of friction, whereas temperatures tend to rise much higher in automatics. As a result, each requires different fluids. Your Crain Ford technician will know the difference and service your vehicle accordingly. What Are the Warning Signs for Transmission Problems? Aside from the most obvious indicator (the blinking transmission light on your dashboard array), certain sights and sounds could be warning you that your transmission needs service. Grinding If your gears make a grinding noise when changing, it's a sure sign things are not going smoothly and it's time to have your transmission checked. Hesitation If there is a momentary delay between shifting and gear change, that is also an indication your transmission is failing. Smell Just as with the engine, an acrid, burning odor is a clear warning that something is wrong. Have your vehicle checked immediately. Seepage Keep an eye on your garage floor or driveway. When oily stains appear, it's a telling sign that fluids are leaking from your vehicle. If they're of a red or green tinge, it could be transmission fluid. What Does Crain Ford Transmission Service Entail? A full service of your transmission at Crain Ford includes a flush, gasket, fluid change, filter replacement, hose and pan inspection, and a multi-point inspection on all other transmission components. Our service technicians are highly trained and OEM-certified experts. Don't wait for your vehicle to develop transmission troubles or any other problems. Come into Crain Ford or make a service appointment now. We'll keep it running like a dream. Image via Ford.

The Top 6 Signs of a Faulty Ignition Coil

While on the road, ignition coils turn the relatively low voltage of a car's battery into a whopping 30,000 to 40,000 volts to ignite the combustion process. Each of your coils should last 100,000 miles or more, but eventually, all ignition coils start to falter. Here are the symptoms of a faulty ignition coil to look out for. If you notice the following issues, visit your local Ford dealer to have the malfunctioning coil cleaned or replaced. Misfiring Engine A spark plug relies on its ignition coil to keep firing more than 30 times per second. This steady stream of sparks continually ignites the fuel-air mixture inside each combustion chamber, powering your engine. If one of your ignition coils stops doing its job properly, the corresponding combustion chamber will start misfiring. You're likely to hear the engine coughing and sputtering. It might also jolt and shudder. Rough Idling Even with just one failing ignition coil, your engine will begin to struggle when idling. Rough idling feels like the engine might fail altogether at any moment. And if more than one of your ignition coils falters, you might indeed stall while pausing at a traffic light. Loss of Power While working less efficiently, your engine will lose some of its power. This is often most noticeable when attempting to accelerate. It becomes dangerous to overtake other vehicles as you might not have access to the necessary burst of speed. Falling Gas Mileage When a coil breaks down, your engine keeps injecting fuel into the cylinders at the same rate. But this fuel is no longer combusting as efficiently as it should. The result is reduced fuel efficiency and less bang for your buck at the gas station. Backfiring When the fuel-air mixture inside a combustion chamber stops burning away properly, an excess of fuel can build up in the chamber. This excess fuel can build up and then suddenly be released into the scorching-hot exhaust headers. This sometimes causes a bang as it ignites and you'll often see black smoke emitting from your tailpipe. Car Won't Start With one failing ignition coil, you'll often find it harder to start your engine in the morning. If more than one ignition coil has bitten the dust, you might not be able to start your car at all. How a Ford Dealer Inspects Your Coils When a technician takes a look at an ignition coil, they can check the voltage with a multimeter tool and also with a spark test. They can also swap out the coil with a new one to see if that clears up the engine trouble. A failed ignition coil can sometimes be cleaned to restore functionality. But more often, it will need to be replaced. Visit Crain Ford of Jacksonville today to have your ignition coils examined, cleaned, or replaced. Our courteous, knowledgeable staff can guide you through our extensive range of vehicles and services. Image via Ford.
