The Common Signs of a Malfunctioning Mercury Topaz Harmonic Balancer
The Mercury Topaz harmonic balancer is built to reduce the vibration from the constant rotation of the crankshaft and the cylinders in your car's engine. However, this car part is not built to last, and it will eventually deteriorate and show signs of wearing down. If you begin to feel that your car is starting to become unusual, then you should do some troubleshooting immediately. Below are some of the common symptoms you can encounter with a faulty Mercury Topaz harmonic balancer:
Strong vibration and noise from the engine
When the harmonic balancer of your car begins to fail, you will feel an increase in vibration of your car's engine. Aside from that, you'll also hear a loud, irregular noise when the vehicle accelerates. These can be signs that the rubber-to-metal bond of the balancer has been broken, and its metal portion is moving over the rubber which creates the loud noise. You shouldn't ignore this problem because a malfunctioning balancer can cause damage to other engine parts such as the a/c compressor and alternator and it will also cause leaks.
Various drive-belt problems
Since the harmonic balancer also works as a pulley for your car's drive belt, a faulty balancer can cause a drive belt to slip, create noise, or become damaged. This will lead to inefficient acceleration, sudden decrease in fuel economy, or engine misfiring. A slipped drive belt can also cause the a/c compressor to malfunction and stop working. Before any of these problems worsen, you should replace both the drive belt and the harmonic balancer. Remember to replace the parts at the same time because if only one of these parts is replaced, the malfunctioning part will still cause damage.
Poor ignition timing
A malfunctioning Mercury Topaz harmonic balancer won't be able to stabilize the camshaft sensor which will cause the sensor to send erratic signals to the vehicle's computer. One possible effect of this problem is a bad ignition timing of your car or a total start failure. When this happens, you'll notice that the car's ignition will still crank to show that the engine is still engaging. However, since there is no right timing, the engine will not start successfully.
