1.6L GA motor..

hi. i have a 1998 nissan sentra, 1.6 L. I need to replace the power steering belt. i have the part, it's just that getting in there to loosen off the worn belt is a really tight fit! how can i squeeze in there, and how can i replace it with a new belt? Do i have to jack up the vehicle and do it from the underside?

Hey PARAONZE,

Replacement of the belt is a straightforward job. You need to loosen the alternator adjusting bolt and pull at the belt to loosen it.

Here is a guide that will help along with a diagram, please let me know if you know anything else.

My belts are old on the car and i want replace them. i had no problem with theback belt getting it on. but the power steering belt i can't get it loosened. I loosened the tension bolts. Is there any others screws I need to loosen to get the belt on.
Your help is much appreciated

There's a bolt on the bottom of the power steering pump, which must be loosened so the pump can move forward, so the belt can be removed.

To change the serpentine belt on a 2002 Nissan Sentra GXE with a 1.8 lit engine, what part do you loosen to replace the belt? Is there an easier way to remove the first belt to put on the serpentine belt?

see diagrams

belt broke and water pump seized. We have replaced the water pump and the belt but the car won't start now

Check the valve timing could be off when you replaced the belt-

Rotate the belt tensioner in direction of arrow and remove belt from pulleys. Install new belt according to belt direction.

i can't figure out what bolts to loosen so i can change out the ac compressor and water pump belt. i'm looking for a tension wheel to loosen but it does not have one. this is a nissan sentra 1996 1.6 automatic gxe. thanks.

For the A/C, you need to loosen the tension on the alternator. There are two bolts/nuts to loosen. The first one is the nut that is holding the tension bolt, and then the tension bolt itself. Once that is done, you can remove the belt from the alternator and A/C pulleys.

For the water pump, it is similar, but you need to do it on the power steering pump. If you are looking at the front of the engine (where all the pulleys and belts are), the P/S pump will be on your left hand side, next to the thermostat.

After loosening the adjusting bolt at power steering pump, the pump should be able to be moved inwards to release the tension on the belt.
Pull hard at the belt. Losen the power steering pump lower bolt if necessary.
