Leaking steering pump/box, 2002 cavalier This car has natural gas setup. is this a problem for repairing.

The NVLD (natural vacuum leak detection) this uses a natural device that follow gas principles,the device is a open vacuum switch,a normally closed solenoid,it is actuated by a solenoid and a diaphragm,The NVLD is located on the atmospheric vents side of the canister on top of the canister outlet

Chevrolet Cavaliers have power steering installed as standard equipment. The power steering is assisted with hydraulic pressure generated by the power steering pump. The pump circulates the fluid and makes turning the steering wheel very light and responsive to the touch. A sure sign the power steering pump is failing is when steering becomes more laborious; also look for leaking power steering fluid puddled under the car. Removing a power steering pump is not a difficult project and is the first step to repairing the power steering system.

1. Serpentine Belt

   • The serpentine belt on the front of the Cavalier's engine provides the power to operate the power steering pump. You have to first remove the belt to free the power steering pump's drive pulley. Underneath the Cavalier is a spring-tensioned pulley keeping the serpentine belt taut. Use a socket wrench to grab the center hex nut on the tension pulley and turn it so the belt becomes loose. Remove the belt from the pulley and then from the other wheels and pulleys on the engine.
     

   Tubing

   • A tube runs from the pump to the power steering assist mechanism in the Cavalier near the front axle. This hard tube has two fittings on each end for a connection. Use a box-end wrench to disconnect one end of the tube underneath the Cavalier. Be careful because some power steering fluid will leak. Just hold your finger over the hole and set a container underneath the tube and wait for the fluid to drain.
     

     Once the fluid finishes draining use the box-end wrench to disconnect the tube from the power steering pump. The tube is bent and twists to make its way through the engine bay from the pump to the power steering assist. There's no need to remove it from the bay. Just push it aside.
     

   Pump

   • The power steering pump is bolted directly onto the engine block. To remove the pump, unscrew the fasteners securing it to the engine. There may or may not be thread lock compound used to seal the bolts onto the engine. If the bolts do not easily turn use some force to break the thread lock. Do not worry about doing this. Breaking thread lock is the only way to get a bolt free. Once the bolts are out, lift the pump out of the engine bay. Again, though, be careful because as you move the pump some remaining power steering fluid may drain from the access port where the tubing was connected. You might want to get a shop towel to hold over the port when moving the pump to avoid a dripping mess.
     

the most common power steering leak in these cars if from the fluid cooler line - it runs straight down from the pump, behind the frame, then up to the rack. if the leak looks like its coming from the passengers feet area, this is the leak. very common. unfortunately, it is slightly beyond the scope of a home repair as the front frame needs to be dropped down slightly to gain access to change the line. the line costs aprox. $150 CDN and i believe about 1.5 - 2 hours shop time for labor. good luck!

none of the above have any bearing on the failure of said parts in any way or form.as they are not even connected to each other.

it should have a pump is there any whining noise when steering if so ad power steering fluid and check for leaks your owners manual will tell you what fluid and the pump will be on the front side of engine

sounds like one of your pulleys. power steering pump, altanator, ac compressor, something along those lines.

not much info on the car or year but here goes...the pump is located on the engine and has a pressure hose running to the steering box. The pressurized fluid goes through from the pump into the box to assist turning of the wheel. There is a low pressure return hose coming back from the box to the pump. That should be all of the lines running to it unless it has a turbo which I've never seen a cavalier have..

Dealer, but did you check the Power steering fluid level??or any leaks. There are two hose that connect to the gear box from the power steering pump. if the pump is low on fluid you lose your power steering, if the hose has a leak or it blew and lost the power steering fluid then you lost your power steering again. 
Check the fluid level to the power steering pump and any leaks or broken hose to the gear box.
Keep me posted, be glad to help and good luck.

Believe it or not there are some problems you should take to the dealer. It never was the gear box, its a defective steering column bushing. That problem had a factory notice and the dealer would have diagnosed it immediately an fixed it free parts +$40.install. Tahoes get that problem.

does the pump it's self leak or are just having to add fluid constently?
