I have a Mazda RX-3. I can smell a burning odor coming from under the hood after I drive 25 highway miles. What could it be?
A burning smell coming from under the hood of your Mazda RX-3 can be caused by a number of reasons. It could be a fluid leak, like the engine oil, coolant, power steering fluid, or transmission fluid that comes into contact with hot engine parts. These fluids don't evaporate but instead burn slowly, causing a burning odor that is sometimes accompanied by smoke. Another possible cause is an electrical malfunction that causes your car's wiring to get hot enough to melt. You might also have had a piece of debris that came into contact with hot components and it emits a burning smell. You will need to inspect the undercarriage carefully so you can find the cause of the burning smell. Start by looking for leaking coolant hoses, inspecting the power steering hoses, and checking the fluid level of your car's automatic transmission, if it has one.
The battery of my Mazda RX-3 is not charging. Is there a way to fix this?
Troubleshooting your Mazda RX-3's battery and finding a way to fix it is highly possible. First, you must focus your attention on the battery itself. If your car stopped running, jumpstart the engine then remove the jumper cables and wait. If your vehicle keeps running after several minutes, then the battery's likely the problem and you might need to replace it. You should also check the battery cables to make sure that they're in good condition, as corroded cables will not deliver the full current flow your car needs to operate properly. However, if the battery doesn't hold its charge and your car's engine stalls, look at the alternator. Even though the battery may have enough power to start the engine, it will eventually lose energy if it's not being recharged by the alternator. You can confirm that the alternator is faulty by cranking over the engine and turning on the headlights. If they start bright and then slowly fade, then the alternator is not delivering the proper charge. You should also inspect the alternator cables for signs of abnormal wear, such as cracking and fraying, and replace or tighten these cables as necessary.
My Mazda RX-3 starts okay but stalls suddenly. How can I find what's causing this?
The stalling is likely caused by either a problem in the electrical system or in the fuel system. When the engine of your Mazda RX-3 stops running, it's because it is not igniting gas in the cylinders. This only occurs either because there is no as to ignite or because it doesn't have the electrical charge to do so. First, drive your car up and down hilly roads and observe the engine's performance. Does going uphill cause it to stall? If yes, then the fuel filter might be clogged. Simply replace it and do so again every 7,500 miles to prevent this from happening. Other things to inspect are the distributor or the carburetor, which you need to inspect and repair or replace.
