If my car is low on oil, will the check engine light turn on?
The short answer is: maybe. If your car is low on oil, it may trigger the check engine light to turn on. However, there are a number of other factors that can also cause the check engine light to turn on, so it's important to consult your owner's manual or a qualified mechanic to diagnose the problem. In some cases, the check engine light may come on because of a loose gas cap or a faulty sensor. Low oil levels can cause serious damage to your engine, so it's important to keep an eye on your oil level and top up as needed.
Do I need to press the rear wheel bearing replacement or not?
Replacing a rear wheel bearing can be a tricky proposition. If the old bearing is still in good shape, you may be able to simply press it out and press the new one in. However, if the bearing is damaged or otherwise worn out, you'll need to press it out using a bearing press. The process is relatively straightforward, but it's important to make sure that you're using the right tools and taking the proper precautions. With a little care and attention, you can replace your rear wheel bearings without any problems.
Water pump leaking at the gasket. Can I just replace the gasket?
Yes, you can replace the gasket. You will need to remove the pump from the engine and take it apart. Be sure to clean the old gasket material off the pump and engine surfaces before installing the new gasket.
It is also a good idea to check the condition of the impeller and wear a ring while the pump is apart. These parts can wear out and cause the pump to leak. If they are worn, you will need to replace them as well. Follow the instructions in your repair manual on how to do this.
How much would it cost to replace the rear main seal?
It's not just about replacing the seal itself but also about disassembling part of the engine to properly access and replace it. Some estimates put the cost at around $350-$450 for labor alone. However, this cost can vary depending on the make and model of your vehicle, as well as your location and the specific shop you take it to. It may also be worth considering trading in your current car for a newer one that doesn't have a leaking rear main seal. Ultimately, the cost to replace the seal is something to factor in before making any decisions about your car's future. Happy (and leak-free) driving!
What's the difference between idle control valve and auxiliary idle air control valve?
The idle control valve regulates the amount of air that bypasses the throttle plate to maintain a constant engine idle speed. In contrast, the auxiliary idle air control valve regulates the amount of air that bypasses the throttle plate when the engine is cold.
The idle control valve is located on the engine and is controlled by the computer. The auxiliary idle air control valve is located on the throttle body and is controlled by a vacuum regulator. When the engine is cold, the auxiliary idle air control valve allows extra air to bypass the throttle plate to keep the engine idling smoothly. As the engine warms up, the auxiliary idle air control valve closes, and the idle control valve takes over.
Can I use a MAF cleaner on a throttle body?
Yes, you can use a MAF cleaner on a throttle body. However, you should only use a MAF cleaner if your throttle body is severely dirty. If your throttle body is only mildly dirty, you can clean it with a rag and some soapy water.
And be sure not to use throttle body cleaner on a MAF sensor, as this can damage the sensor. Only use a MAF cleaner on the throttle body itself.
And also, don't forget to clean the IAC valve (idle air control valve) while at it. The IAC valve is on the throttle body and can also get dirty. A MAF cleaner can be used on the IAC valve, but only if it's severely dirty.
