Trying to Change Power steerig belt . need help in loosening off pump puly, dropped off Alt belt already. to get access to power steering belt , and untightened slide bolt on top of pump,, but still cant slide pump towards engine to get the pump belt off,, what other bolts are needed to do this simple job ? thanks

Belt Tension-er or Belt Idler. Alternator, Ac or Power steering pump bearings.

Loosen the bolts that attach the power steering pump to the bracket. then push the pump down. this should make the belt loose enough to get off. then put the new belt on. take a pry bar and stick between the motor and the power steering pump through the top. push on the pry bar to raise the power steering pump and tighten the belt. while pushing on the pry bar to keep tension on the belt tighten the bolts that you loosened and you've changed your power steering belt. this can be done by one person, but it's a lot easier with two.

Hi, Please follow below steps :

-. Jack up front wheel and remove the tires
-. Remove the Motor Mount next to the Power Steering Pump and timing belt cover

-. Loosen the Alternator/Water Pump belt.
-. Loosen the Power Steering/AC/Tensioner belt by loosening the Tensioner Bolt first.

-. Remove the power steering pump bracket. Leave the pump attached to the bracket.
-. Remove the Water Pump Pulley.

-. Now it's time to remove the Crank Pulley.

-. Remove the Timing Cover bolts.

-. Remove and replace the crankshaft sensor

A/C Compressor Belt

1. Remove the alternator/power steering and water pump drive belt to gain access to the air conditioning belt.
   

2. Loosen the tensioner pulley locknut, then turn the adjusting screw to raise or lower the tensioner pulley assembly. Remove the belt.
   

To install:

1. Install the belt.
   

2. To adjust the belt, loosen the tensioner pulley nut and adjust the belt tension by tightening the adjusting screw. Tighten the pulley nut to 40 ft. lbs. (54 Nm) after adjustment.
   

3. Install the alternator/power steering and water pump drive belt and adjust.
   

4. Start the engine and check for proper belt alignment and any abnormal noise.
   

Belt adjustment is made by loosening the power steering pump and turning the transverse bolt just below it. Loosen it up to put the belt on and use to adjust.

First go to Nissan's help forum page. Use this link: http://x.nissanhelp.com/forums/index.php

You can get a free login and download up to two files a day using the free login. You want the MA maintenance file of your vans manual. This will include the belt tensions and placement.
You will need to remove the plastic cover on the passenger side of the engine to be able to access the belt tensioners on the alt. and power steering pump. Nissan likes to use the same basic tensioners on most of their stuff. The air pump and air conditioner use idler pulleys, you loosen the bolt in the middle of the pulley enough to allow the pulley to move, no more. there is a bolt with its length toward the center of this pulley, when you loosen this bolt the pulley will start to move down and loosen the belt. repeat this process for both the air pump and the air conditioner. The alt. and power steering you loosen the bolt that secures the tensioner, than you can back off the long bolt in the tensioner to loosen and remove the belts.

I usually check each new built with the old one for length and label its sleeve by function as I take each one off. Makes matching them up when you put them back on much easier.

Hi, no need to raise the engine. you can use these steps to replace your pump.

To replace the power steering pump, proceed as follows:

1. Disconnect the power steering return hose from the remote reservoir or pump. Allow the fluid to drain from this hose into a drain pan. Discard the used fluid.
2. Loosen the bracket or belt tension adjusting bolt, and the pump mounting bolt.
3. Loosen the belt tension until the belt can be removed. On some cars, it is necessary to lift the vehicle on a hoist and gain access to the power steering pump from underneath the vehicle.
4. Remove the hoses from the pump, and cap the pump fittings and hoses.
5. Remove the belt tension adjusting bolt and the mounting bolt, and remove the pump.
6. Check the pump mounting bolts and bolt holes for wear. Worn bolts must be replaced. If the bolt mounting holes in the pump are worn, pump replacement is necessary.
7. Reverse steps 1 through 5 to install the power steering pump. Tighten the belt as described previously, and tighten the pump mounting and bracket bolts to the manufacturer's specifications. If o-rings are used on the pressure hose, replace the o-rings. Be sure the hoses are not contacting the exhaust manifold, catalytic converter, or exhaust pipe during or after pump replacement.
8. Fill the pump reservoir with the manufacturer's recommended power steering fluid, and bleed air from the power steering system as described earlier.

You need to loosen the large mounting bolt at the base of the power steering pump as well as the tension adjusting bolt on top of the unit that is attached to the slotted arm. You may need to use of a large pry bar to gently force the pump inwards to gain enough slack to remove the belt.

Removal & Installation

1.6L Engine
A/C Compressor Belt

1. Disconnect the negative battery cable.
2. Loosen the A/C compressor mounting bolts.
3. Pivot the A/C compressor towards the engine in order to relieve the tension on the belt.
4. Remove the A/C compressor drive belt from the pulleys.

To install:

1. Properly route and install the A/C compressor drive belt on the A/C compressor, the power steering (if equipped), and the crankshaft pulleys.
2. Adjust the A/C compressor drive belt to obtain 6-9 mm (0.24-0.35 in) deflection.
3. Tighten the A/C compressor mounting bolts to 13-20 f t. lbs. (18-28 Nm).
4. Connect the negative battery cable.

Alternator Belt

1. Disconnect the negative battery cable.
2. Remove the power steering pump and the A/C compressor drive belt.
3. Loosen the generator mounting bolts.
4. Pivot the generator towards the engine and remove the accessory drive belt.

To install:

1. Properly route and install the generator drive belt on the pulleys.
2. Adjust the alternator drive belt to obtain 6-8 mm (0.24-0.32 in) deflection for a used belt or 5-6 mm (0.20-0.24 in) deflection for a new belt.
3. Tighten the generator mounting bolts to 17 ft. lbs. (23 Nm).
4. Install the power steering and the A/C compressor drive belt.
5. Connect the negative battery cable.

Power Steering Pump Belt

1. Disconnect the negative battery cable.
2. Loosen the power steering pump mounting bolts.
