My brake pedal sticks to the floor after depressing it, and it doesn't come back to its default position. Can you give me a quick guide on how to diagnose this problem?
The first thing you need to do is to check the fluid level in the master cylinder. If you notice that the reservoir is empty or has a very low fluid level even if your brake pads and shoes are in good shape, then the system is probably leaking. Remember not to use your Oldsmobile Dynamic if this happens. Replace your brake pads and shoes if they had a contact with the brake fluid. You must also inspect the calipers and wheel cylinders for leakage, and replace them if needed.
My engine suddenly won't start. I've noticed that I forgot to switch off the radio before heading to the grocery store. How can I check if the battery is discharged or if the battery is already dead and needs to be replaced?
It is an advantage that you know you have left your radio on for a long time because it is easier to diagnose the cause as to why your engine suddenly won't start. Always keep in mind that a drained battery or a dead battery will not give your engine enough power to turn your vehicle on. You can also hear a clicking sound when attempting to start your engine. You may check if the battery is really drained by turning on the windshield wipers. If they don't move like they usually would or they move but very slow, then your car's battery is probably close to empty. If your battery is new, then you are very lucky because you can easily fix the problem by recharging it immediately. You can do this by jump starting your car and letting your engine run for a moment to let the battery recharge. But if you have a car battery charger with you, then you may opt to use it instead of jump starting your car. These might not work for batteries that are 4 to 5 years old already. Charging them won't even help you to start your engine. In this case, you will really need to replace the battery already.
I have noticed a gasoline smell inside my Oldsmobile Dynamic, and I know it is very dangerous. What are the common reasons for this problem?
This gasoline smell can come from an injector leak. You just need to replace the o-rings and the seals to stop the emission of this gasoline smell. Check your fuel tank if there's a puncture or leak. You can easily notice it when your car is in idle because there's a spot on the pavement right under your vehicle. This is very dangerous, especially when people who smoke cigarettes accidentally threw them out and fell near the leak spot, because this might cause your vehicle to catch a fire. A crushed and broken fuel line can result in leakage, and it will trigger a mist or vapor to come out. Most people take the charcoal canister for granted not knowing that it can cause a fuel or gasoline smell when cracked or if it has a leak. Always check your gas cap if it is in proper place, not missing, or faulty.
