You know how heavy your engine and transmission are, so you can imagine how tough the parts that hold them onto your vehicle's sub-frame must be. Not only must they support the weight, they also have to isolate vibrations and noise from the passenger cabin. Pretty tall order, wouldn't you say? The parts that face that task daily are called the motor mounts, or engine mounts. They are usually made of rubber with steel brackets. Others contain a liquid for vibration and sound isolation. Most vehicles have three or four motor mounts, and while rubber or hydraulic liquids do a good job of damping the vibrations from the engine, they also have their limitations. The problem with rubber is that it gets old and brittle. Plus, if there's an oil leak anywhere in your engine and oil gets on the rubber motor mounts, rubber will deteriorate even more quickly. As for the liquid motor mounts, they can develop leaks and stop working. Here are sign ... read more

When the weather gets colder, sometimes the noises your vehicle makes will change. For example, you may notice a whining sound when you get going in the morning. It may go away when the vehicle warms up, but it's best not to ignore that sound because it could be a warning of worse things to come. Colder temperatures cause different components to behave differently. Let's take a look at a few of them. First, the fluids in your vehicle. Cold temperatures can make them behave a little differently, such as engine oil, transmission fluid and power steering fluid. Those characteristics could change if the fluids are older and full of contaminants. Belts also can create a whining noise when cold. Since they turn pulleys that move other things, several factors can create issues. Increased friction can change proper tensions on belts. Plus, belts change as they age and may crack, get loose or develop a glazed surface. Belts and pulleys also must b ... read more
