A "Mounting" Problem (Motor Mounts)

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 signs a motor mount is going bad.  You may hear a loud clunking or banging sound under the hood.  That means the weight of the engine is shifting around enough to bang against other metal parts.  You may feel bad vibrations, and the engine may feel like it's moving around in a strange way.

When things get to that point, your vehicle can be damaged from that heavy engine knocking against things, and its time to replace one or more motor mounts.  Schedule a visit to your vehicle service facility. There, a technician will assess your motor mounts; if one bad one is found, it's not unusual that others are likely to fail soon and should be replaced before they do.

Because all vehicles are configured differently, some motor mounts are easily replaced.  But others can be much trickier, take a lot longer and therefore are more expensive to replace. 

It's important for your engine's health to make sure motor mounts are sound and solid.  You will maintain that quiet, vibration-free ride and could save your engine and transmission from major wear and tear.

Darrell's Firestone Advice: Don't Overlook These 10 Automotive Services

Organization is the key to managing a busy life in MI. So setting up an annual calendar for vehicle care can keep Farmington residents on top of preventive maintenance. But you can't just write “oil change” every few months on the calendar. Modern vehicles have many systems that are vital to the safe operation of a vehicle, and they all need to be inspected. Farmington residents can't afford to overlook any of them.

The following is a list of preventive maintenance services that are often overlooked by vehicle owners in the Farmington area. They are not presented in any particular order.

1. Darrell's Firestone Power Steering Service. Moisture gradually builds up in your power steering fluid, which can lead to corrosion in your steering system. The fluid also gets dirty, which can gum up your steering system. The fluid needs to be replaced periodically.

2. Darrell's Firestone Wheel Alignment. Wheels that are out of alignment will cause a vehicle to pull to one side. This is dangerous for Farmington residents and can lead to accidents. Also, it causes uneven and rapid tire wear, which means tires must be replaced more often.

3. Darrell's Firestone Differential Service. They are part of the drive train system that transfers power from the engine to the wheels. Damage or wear in this system can make a vehicle undriveable.

4. Darrell's Firestone Cabin Air Filter. Your vehicle may or may not be equipped with a cabin air filter. Its job is to remove dust and pollen from the air that enters the passenger compartment of the vehicle. If this filter clogs, it can stink. So check your owner's manual to find out if your vehicle has a cabin air filter. If so, come visit us at Darrell's Firestone and get it changed according to the recommended schedule.

5. Darrell's Firestone Timing Belt Replacement. Most passenger cars and some vans and trucks have timing belts. Farmington residents can check their owner's manual to find out if their vehicle has one. If so, you can't drive without it. And if it breaks while on the road, you may be looking at thousands of dollars of repairs. So it is important to inspect it occasionally. If your vehicle has close to 60,000 miles/100,000 kilometers or more on it and you haven't had your timing belt replaced, then you need to find out the recommended replacement interval NOW.

6. Darrell's Firestone Transmission Service. Transmission fluid gets dirty and has to be replaced. If not, you risk repairs.

7. Darrell's Firestone Air Conditioning Service. The refrigerant in your air conditioner needs to be replaced periodically. This fluid doesn't just refrigerate air; it provides lubrication to the air conditioning system and conditions seals. Lack of fluid can damage components.

8. Darrell's Firestone Brake Service. Even if your brakes are quiet and working well, the brake fluid still might need to be changed. Over time, moisture builds up in brake fluid. Water has a different viscosity than brake fluid, so the brakes can't compress properly when there's too much moisture in the fluid — and you shouldn't need to be told how it is to drive with brakes that are compromised. Moisture in your brake fluid can also corrode parts in your brake system, causing it to fail altogether.

9. Darrell's Firestone Coolant System Service. Antifreeze is another fluid that needs to be changed regularly. If not, it actually becomes corrosive and begins to damage your cooling system. Eventually it can eat holes in your radiator.

10. Darrell's Firestone Fuel System Cleaning. Over time, your fuel system just gets gummed up, which can interfere with the flow of fuel in a number of ways.

Of course, your next question should be: How often do I need to get all of this done? Well, the answer varies depending on which service we're talking about, the make and model of your vehicle, the climate where you live in MI, your usual driving conditions and your driving habits.

But don't lose heart. Your owner's manual will give you a recommended service schedule for most of the service items listed. And you can get quality auto advice from your friendly and knowledgeable Darrell's Firestone service advisors to help you meet the service intervals that suit your vehicle.
