This is easy job, and very difficult at the same time. In general, you just remove the serpentine belt, remove the coil pack if located over the belt for wrench clearance, use a large (approx 15/16 inch I think) socket and breaker bar, remove center bolt, pull off the old balancer, and install new, torque to approx 135 foot-pounds. However..... the old bolt may be seriously overtightened from the factory, and restraining the old balancer from turning takes a HUGE strap wrench. The balancer bolt on my 87 Park Ave took approx 250-300 foot-pounds torque to loosen it. Wow. Forces here can be large, and serious injury can result. You might consider taking to a shop-- this job can get ugly.
You will need special tools like: harmonic balancer puller, and impact wrench.
On the harmonic balancer/driverside
The crank sensor is located behind the Harmonic balancer. Try not to break the rubber within the Harmonic balancer when removing or on the safe side replace both the Crank sensor and the Harmonic balancer ( the big pulley on the bottom - most part of the engine.)
They are on the harmonic balancer but are they on the drivers side or on the passenger side?
at the front of the engine,next to the harmonic balancer
Easiest way is with an air impact. There are strap clamps available that would go around the harmonic balancer that would hold it while the bolt was tightened.
If you look at the harmonic balance you will see on the front of it a medium size circle. That will be your timing mark.
The "Harmonic Balancer", is found under the hood, its the biggest pulley on the bottom of the engine, there are three drivebelts, one for the fan and waterpump, ac and alternator.
take off the right wheel and the cover wall and you wll see it
Normal right hand thread. Counter clock wise to loosen.
The Crankshaft sensor is located behind the Harmonic Balancer on the front-passenger side
Behind the harmonic balancer. You will need to remove the right front tire, remove the access panel to the engine (through the wheel well), remove engine belt, remove harmonic balancer & pulley with a puller. Remove & replace crank sensor, align sensor with an alignment tool, replace balancer with an installer tool.. BE VERY careful with the balancer, the backside of it has a hall effect style blades. bending these blades will junk the balancer.
== == I do believe if you hear a knocking noise that your crank shaft could be failing. Which means you will need a new engine. Have it checked out. Replace the harmonic balancer they will make a bad knocking noise. When you start it and the oil light goes out and it knocks, this is what is wrong with it.
the oil filter is on the driver side front next to or almost completely under the harmonic balancer, best accessed from under the front
89 Buick park ave install a heater coil
There are numbers stamped into the harmonic balancer, if you can't see them, take some sand paper and clean the balancer off, you should see the pointer that points at what the timing is when you look down from the top of the engine bay. The best way I've found to see your mark, is to use a white or yellow grease marker and put a line on the balancer where the particular degrees you want to set it on.
Wonderland Avenue was created in 1989.
Try changing the crank sensor it worked on my 1993. Behind the harmonic balancer.
I HAD A 1990 BONNEVILLE I HAD THE SAME PROBLEM WITH.IT TURNED OUT TO BE THE CRANK SENSOR.ITS BEHIND THE HARMONIC BALANCER. HOPE THIS HELPS
If it is a 2.8 or a 3.1, the crank shaft position sensor is located under the rear exhaust manifold, right above the transmission housing. Its a small sensor with a 8mm screw holding it in place. Be careful pulling it out, the are known to break off in the block housing. Then the fun really begins to get it out. If its a 3.3, or a 3.8, it is located under the harmonic balancer. You can take the sensor off without taking the harmonic off, but it is ultimately easier to take the harmonic off because you have to adjust the sensor to the timing ring on the harmonic. Its easier to do when its apart.
McKinney Avenue Transit Authority was created in 1989.
Its not an electrical fuel pump its a mechanical fuel pump right next to the harmonic balancer in another words called the crank shaft pulley or under the exhaust intake front left side driver side
How do you install an after market stereo in a 1989 acura legend?
It is part the process in changing a timing belt. If you look at the instruction for changing a timing belt you can stop once you reach that point. It does not require removing the timing belt though just most of the pulleys, Idler belts and if you want to be safe the radiator. The bolt holding the pulley and harmonic balancer can be tough to get out, and getting an impact wrench in there to pull that bolt is almost imposible without removing the radiator. The engine crank will turn freely as well which compounds the difficulty. http://www.ehow.com/video_4978619_timing-belt-replacement-remove-harmonic.html http://www.justanswer.com/ford/143nf-replace-timing-chain-1989-ford-ranger.html
For model year 1989 General Motors did not produce the Buick Park Avenue. The soonest production date to 1989 was the 1991 Park Avenue. The 1991 Park Avenue was offered in 3800 engine in supercharged or naturally aspirated. The part numbers for electronic control module (ECM) or "computer" will vary based on the exact engine for model year 1991s.
