Engine problems can develop due to worn or damaged components. If a problem develops in the engine, it will grow worse as time passes and can lead to damage to other engine systems. As your Nissan dealer, we can repair any potential problem for you. These are a few examples of issues that we can fix. Blocked Catalytic Converter Catalytic converters have been a part of every vehicle in the US for almost fifty years. The converter's function is to change dangerous and toxic chemicals produced by combustion into harmless ones to reduce air pollution. A converter uses chemical reactions, extreme pressure, and high temperatures to change dangerous chemicals. The conversion process in the converter produces carbon. Carbon gradually accumulates and can block the exit from the converter into the exhaust system. If this happens, engine gasses are forced back into your engine. These gases increase pressure in the engine and can cause the engine to stall. We can fix this problem by cleaning the converter to remove the blockage. more Engine Knocking A strange knocking sound from your engine is a sign of trouble, as it can lead to permanent engine damage. The sound is caused by high pressure in the engine and excessive engine heat. There are several causes of this problem, including a blockage in the converter, electrical issues, or a high fuel-to-air ratio in the engine. We saw above how a blocked converter can increase pressure in the engine. Electrical problems like damaged spark plugs or the wrong octane fuel cause the fuel-air mixture in a cylinder to burn unevenly. Uneven burning generates small shockwaves at the wrong time, which produce a knocking sound. Our technicians will identify the cause of the knocking and fix it, and your engine sounds will return to normal. Leaking Coolant Coolant plays an essential role in your Nissan's cooling system. It is a mixture of antifreeze and water and can absorb heat. Liquid coolant is pumped through your engine and flows over the hot engine components. It absorbs the heat radiating off these components and transports the heat to the radiator. Once inside the radiator, the hot coolant enters the radiator tubes, where the heat is removed by heat exchange. A coolant leak can be caused by worn seals, a hole in the radiator, or a worn radiator hose. As coolant leaks out of the system, the pressure in the cooling system drops. The pressure drop also serves to slow the movement of the remaining coolant. As the cooling system slows down, your engine will start to overheat. We can fix this problem by tracing and sealing the leak, then we'll refill the coolant. If you have a problem with your engine, our Nissan-trained technicians can repair it.

Properly working headlights are an essential part of any vehicle's safety system. Without them, it's nearly impossible to navigate darkened streets, and other vehicles won't see you coming. Fortunately, headlight repairs or the installation of headlights is a straightforward service that can be performed by your Nissan dealer. But how can you tell if it's time for new headlights? There are several signs. Is It Time for Your Nissan Dealer to Install New Headlights on Your Vehicle? Your Bulb Is Blown One of the surest ways of determining that your headlights have failed is to examine the bulb. If the bulb has visibly blown, you're likely not seeing any light emanating from the headlamp, and you need immediate replacement. Headlights don't last forever, and it's normal for the bulbs to blow occasionally. But if your headlights need replacement more than once a year, there may be a wiring issue or another mechanical issue at play. more Your Lights Are Dim If you switch on your headlights, and you get only a dim glow instead of a direct beam of light, you may also be due for new bulbs. If you've noticed a dimming in your lights, your dealer can test your bulbs and determine if they need to be replaced. Because headlights are usually installed in pairs, if one is starting to dim, the other is likely to soon follow. Your Lights Flicker If your headlights are flickering or blinking on and off, your vehicle may be experiencing wiring or an electrical connection issue. Flickering can also be a sign that the bulbs are nearing the end of their life. It's always a good idea to get flickering headlights checked out. Your Lights Are Hazy Headlights that have become yellowish or hazy may be due for replacement. It's also possible that hazy headlights are just due for a good cleaning. Sometimes dirt can build up on the inside of the clear lenses that protect your headlights, and it's just a matter of having the professionals at your dealership clear that grime away. Addressing hazy headlights will not only improve safety: it will also improve the look of your vehicle! Your High Beams Don't Work If your regular headlights are functioning properly, but your high beams won't turn on, you may have a fuse or wiring problem, and fixing that issue could necessitate a full replacement of your lights. The service department at your dealership will be able to assess the problem and take care of fixing it. If you've noticed signs that your headlights may be starting to fail, it's important to have your vehicle checked out. Call Coughlin Nissan of Heath and schedule your next service appointment today!
