FAQs—Chevrolet Sedan Delivery
My check engine light is on. Is there something wrong?
Yes. The check engine light turns on when there is something wrong with the engine and the components surrounding it. With your Chevrolet Sedan Delivery, the most common cause why the check engine light turns on is a damaged, loose, or missing gas cap. The gas cap protects the fuel inside the fuel tank from being contaminated and keeps it from evaporating, so if there's an issue with it, your car lets you know through the check engine light. You don't have to worry too much though, since this issue can be easily fixed. However, it is also possible that some other parts under the hood are the ones that are causing the check engine light to come on. It can be a faulty oxygen sensor, clogged fuel and air filters, a damaged catalytic converter, a bad mass airflow sensor, or worn spark plugs and spark plug wires. All these can disrupt the normal operation of the engine, so you need to fix what needs to be fixed, or replace what needs to be replaced.
My brakes aren't working like it should. It doesn't have the stopping power that it used to have. What's wrong with it?
The brakes are your car's primary safety feature, so it is imperative that it works properly. However, if you are noticing that it's not, you need to have it checked immediately. If you are having problems with its stopping power, you should first check the brake pads. They may be already too dirty and the accumulated dirt may already be affecting the brake pads' function. They may already be worn out as well, as they come in constant contact with the wheels. If the brake pads are less than 1/8th of an inch, they should already be replaced.
You should also check the brake fluid, if it is still at the right level. The brake fluid amplifies the stopping power of the brakes so if you are running low on brake fluid, it will definitely affect the performance of the brakes. You should also make sure that brake fluid is still okay to use. Since the brake fluid is hygroscopic, which means that it can absorb moisture, it will deteriorate over time. If there is already too much moisture mixed with the fluid, its ability take the heat will decrease. If your brake fluid is contaminated with water, you are going to have to replace it with a fresh one.
Also, don't forget to check the other brake system parts such as the callipers, rotors, brake lines and so on, for wear and tear.
