Question about 2001 Oldsmobile Aurora

1 Answer

No treads on harmonic balancer. Should there be treads on the harmonic balancer because my serpentine belt came off and upon reinstalation properly I found that the belt had treads on the serpentine belt, but nothing on the harmonic balancer. Is the harmonic balancer missing treads or is this a recall, defect, or a broken harmonic balancer, missing treads. v6 3.5 twin cam engine, 2001 Oldsmobile Aurora

Why is the harmonic balance eating into the timing cover?


On most vehicles today, the crankshaft pulley acts as the harmonic balancer. It also has the grooved outer ring that the serpentine belt rides on. Between the central hub of the balancer and the outer ring is a strip of rubber that the outer ring is pressed onto. This rubber, over time, ages and shrinks. This allow the outer ring to walk inward (or outward) of the centerline of the pulley. This causes the serpentine belt to wear out prematurely and can cause the problem you describe. You need a new harmonic balancer. It comes complete with the rubber and outer ring already attached. Check your belt at the same time to see if it needs replaced as well.

Tip

Replacing the Crankshaft and Camshaft sensors on a 1991 and later Buick Park...


If your car is misfiring in a rhythmical pattern when you first start it up for the day or dieing when engine is hot, it could mean your Camshaft or Crankshaft sensors need replacement.

Important, disconnect negative cable from the battery before doing any work on electrical system. Wear safety goggles.

Tools recommended:
Break Bar, Torque Wrench, ratchet driver and a full metrics ratchet socket set, one Q tip, large straight blade screwdriver, ratchet extension and adapters if needed.

First we'll start with the easiest and cheapest of the two sensors.

Replacing the camshaft sensor:

The camshaft sensor is located on the right side of the engine, behind the water pump pulley.

1. Loosen the screws to the water pump pulley with a breaker bar before removing the serpentine belt. Always turn counter clockwise to loosen.

2.Remove the serpentine belt via the belt tension-er.

3.Use a regular ratchet driver to finish removing the belt pulley from the water pump.

4.Remove the bolt holding the camshaft sensor in place and disconnect electrical connector. Secure the connector with a clothes pin so you don't lose it down in the engine compartment. Clean around the sensor to avoid getting dirt in the engine.

5. Pull the camshaft sensor straight out with a slight twisting motion.

6. Lightly lubricate the O-Ring on the new sensor with fresh motor oil, and install in the engine.

7. installation is the reverse of removal.

Crankshaft
Sensor:

1. Jack up the front passenger side of the car and safely support it on jack-stands.

2.Remove the tire, remove the inner tire well splash guard cover.

3.Before removing serpentine belt, loosen the center bolt on the harmonic balancer/vibration dampener. (crankshaft pulley)

4. Remove serpentine belt via the belt tensioner.

5.Finish loosening and remove the bolt from the harmonic balancer.
Have an assistant help you, using care not to let the weight of the harmonic balancer rest on the bolt as it can be damaged. Gently pry it of with a straight blade screwdriver. Leave the woodruff key in the crankshaft. Use care to not damage the crankshaft during removal as oil leakage could result. Mark the relationship between the crankshaft and the pulley, so you will be able to line the pulley up just right during re -installation.

6. Disconnect the electrical connector from the crankshaft sensor, secure the connector with clothes pin and loosen the bolts holding the sensor pedestal in place.

7.Separate the old sensor from the pedestal, and install the new sensor, just the same way the old sensor came out. Using the suggested crankshaft sensor alignment tool on the back of the harmonic balancer, making sure the fins on the harmonic balancer pass through the sensor's slot and don't hit it. If any fins on the back side of the harmonic balancer are bent, damaged, or missing, replace the harmonic balancer assembly.

Installation is the reverse of removal. It is imperative the crankshaft sensor be aligned properly before engine start up to avoid damage. Use care not to over tighten bolts during installation. Always tighten to manufacturer's recommended torque.

Harmonic balancer bolt is torqued to specs,but there is still play in the pulley.


23880111-k0la5llha3vhnr1ljv3tx424-5-1.jpgYour pulley has a woodruff key like the one in the photo. In order to have zero play, you need to replace the key and the harmonic balancer

I need to chance the crank sensor on a '96 buick park ave. 3800 v-6, what am i going to have to take off to do it ?


Passenger tire, passenger inner well cover, serpentine belt, pulley that attaches to harmonic balancer , nut for harmonic balancer, then harmonic balancer. Sensor is screwed to engine. Disconnect battery prior to and before install of sensor. The 3800 has a special balancer puller designed just for it, not sure were you could rent one it is a specalty tool.

Would a bad map sensor make the car not start?


No, it might make the engine run poorly, but not prevent starting. If you have neither fuel or spark, suspect the combination crankshaft/camshaft sensor located where the serpentine belt passes over the crankshaft pulley. Remove the belt and the harmonic balancer--the sensor is located just behind the balancer. It requires an alignment tool to place the sensor in proper position.
