Pontiac Trans Sport Harmonic Balancer
Frequent Defects Encountered with a Pontiac Trans Sport Harmonic Balancer
How does the Pontiac Trans Sport reduce engine vibration? See, thanks to a fully functional harmonic balancer, the vibration created by the engine's combustion cycle is largely reduced and this provides a more comfortable and convenient ride. But since the part is not entirely immune to wear and tear, it may soon exhibit signs of damage, which may include cracks in the part or even drive belt defects. If the harmonic balancer seems to have already exceeded its service life, better perform some troubleshooting. Luckily, diagnosis should be easy as it involves only the use of a screwdriver, a wrench, and jack and jack stands. So, here are some of the symptoms and the reasons behind a defective Pontiac Trans Sport harmonic balancer:
Drive belt damages
Since the auto's harmonic balancer serves as a pulley to the car's drive belts, there is a risk of damaging the belts when the balancer is no longer functioning well. Usually, a loud noise will be produced by the belt, which would often lead to several other defects like engine misfires and backfires. Most of the damages caused by a defective harmonic balancer might even lead to a decrease in the vehicle's fuel economy.
Excessive engine vibration
The Harmonic balancer is primarily built to help suppress vibration levels from the crankshaft and the rest of the engine parts. So, when this part malfunctions, the first problem commonly detected is excessive vibration. This is usually accompanied by a loud engine noise, which is more prominent when the gas pedal is hit. This might even lead to several other damages like cracks and separations on the balancer. In fact, the vibration may even lead to a misplaced insulator. If all these signs are present, better prepare for a part replacement.
Car start failure
Another manifestation of a defective harmonic balancer is a car start failure. Most of the time, car owners experience bad ignition timing. This is usually a result of an inconsistency in the camshaft sensors, which is a result of a faulty harmonic balancer. Sometimes, the car will be able to crank up but will still be unable to attain spark ignition because of a damaged harmonic balancer.
