This Saturn Aura is a nice car; I have no problem driving it for years now. Lately, however, I've been experiencing the "Check Engine Light" coming on intermittently. The diagnostic indicates there might be a leak in the gas line. I've checked everything and even brought it to the shop. They can't detect the problem though. Any idea what's it about?
There are different reasons why your car's Check Engine Light comes. But, the most common reason is the gas cap—either it's missing or it's not on properly. If the diagnostic is indicating that there might be a problem with the gas line, then this is most likely the reason. When a gas cap is missing or not sealed properly, your car's EVAP system (Evaporation Emission Control system) activates the Check Engine light to warn you that there's a problem. The light will remain on until the gas cap is sealed properly. When this problem is neglected for a long time, it can get costly. Aside from affecting fuel efficiency because of gasoline evaporation, the fuel can also splash out of the tank and can trigger fire. The good news is that replacing the gas cap is not costly and it's easy to find. You simply get one that is compatible with your car's make, model and year.
I recently changed the ignition switch of my Aura. It turns on fine and the engine will crank but after that nothing happens. The engine will not start. Please, I need help in figuring out what could it be! Any suggestion?
Your problem with your Aura is one of the most common problems drivers experience with the ignition switch. This is probably because of a fault in the anti-theft function or in the fuel pump circuit. It could also be because of a problem with the ignition circuit or the engine computer. Check if the anti-theft light in the dashboard is flashing. If it is, it means that your car's computer does not recognize the key or the key fob and is preventing the engine from starting. In some instances, reprogramming your computer will solve the problem. However, in some cases, you may need to replace your smart key or key fob. If your engine is cranking but just slower than normal, you could be having problems with a low voltage to the starter. Check the battery and cable connections.
I recently experienced steam shooting from under the hood of my Saturn Aura after driving for just about 45 minutes. I pulled over, thinking my engine is overheating. But, what's confusing is that I checked the temperature gauge and it was reading normal. I opened the hood and saw water boiling in the overflow. Any help?
Your problem can be because of an engine coolant leak somewhere in your car's engine. This is one of the most common causes of an engine overheating. Possible leak points for you to check are the hoses, radiator, water pump, heater core, head gasket, thermostat housing, oil cooler (in automatic transmission), freeze plugs and the cylinder heads/block. The first thing for you to do is make a visual inspection of the car's cooling system and conduct a pressure test to locate the leak. Make sure to test the radiator cap as well; a faulty cap can also cause the engine to overheat.
If there are air pockets trapped inside the cooling system, the engine may also overheat. Your cooling system should have air bleed valves to aid in the removal of air pockets. If your car doesn't have it, you can do it manually. Start the engine and let it run without the radiator cap or loosen the cap until all the air escapes from the radiator.
