first jack up and support the front passengers side of the van then take the tire off then take the plastic splash guard off then you should be able to see the harmonic balancer from the wheel well opening then your going to need to take off the belt then put a harmonic balancer puller on it and crank it out harmonic balancer puller is absulutely needed to take the balancer off of you could damage the balancer or even wors the crankshaft, the pullers are really cheap compared to a crankshaft
you unscrew it
15mm
between 150-180. anywhere in that area is fine
It is on the front of the motor, it will be the bottom most pully.
the harmonic balancer is the crankshaft pulley approx6 or 7 inch diameter lower pully center of engine the serp belt is driven by power pulley also have a retaining bolt in center
The crankshaft sensor on the 1998 NISSAN ALTIMA is located next to the radiator side of the harmonic balancer
Passenger side (front of the motor) in the middle. Just above the water pump. Must remove cover and harmonic balancer to install. Very difficult.
It's on the inside of the Harmonic Balancer Pully. It shoud be blue in color
socket and force bar on bolt brace against frame and use starter to loosen
If the oil is leaking from the timing chain cover behind the Harmonic Balancer (main large double pulley the belts run on). After removing the belts you need to remove the Harmonic Balancer using a puller, not to damage it, and then replace the seal in the cover. Inspect the back side of the Harmonic Balancer. The seal only seals to the shoulder of the Harmonic Balancer not the back face. If the shoulder's surface is not smooth replace it or it will leak again. Apply some light grease on the seal and mating surface of the Harmonic Balancer and reinstall. Re-install the belts. If it is leaking around the edges of the cover the sealant may need replacing. Also check the condition of the sealant around the oil pan. Both would require removal/cleaning and re-sealing.
the crankshaft position sensor is located right behind the harmonic balancer mounted on the timing cover
You can replace the timing belt on a 1998 Plymouth Breeze 2.0 engine using a Harmonic Balancer Puller 5.
