the chirping noise maybe the belt tensioner with the car running see if the tensioner is bouncing if it it replace it and replace the belt dont spray wd40 on the belt it can cause the belt to come off
its kind of hard to say on the whining noise - could just be a belt. Try spray WD40 on your belts when its idling and see if the noise lessens or goes away. If you have smoke coming out of your exhaust you need to determine the color / smell of the smoke. If it is white / light gray colored and "sweet" smelling then you are burning coolant which means you probably have a cracked head gasket. If it appears blueish and is "burnt" smelling then you are burning oil which means you may have a worn seal, gasket, o-ring, etc. If is dark / black colored then your fuel mixture is too rich which could be a bad O2 sensor, fuel pump, or fuel injectors.
hi, the first thing i would have said the fault was was going to be a fan belt/ alternater belt if this is to loose or to tight then this can give you the noise you are hearing, one way of finding out if its a belt making the noise is to go out and get a spray like wd40 and then spray this on the belt then if the noise goes away you then know that its that belt causing you the problem.
If the belts have not been replaced recently then this could be the cause of your problem, spray the belt with a spray or even soapy water then give you car a try if your using soapy water make sure you get the whole belt wet then try the car if the noise is then gone you know the belt is at fault.
If you have power steering then low power steering fluid can cause the power steering pump to squeek so check the level and fill it up to the highest mark then start the car and turn the wheel fully left then fully right then back to the middle then check the level again. Low steering fluid can cause the noise you hear.
If after doing this its not the belt making the noise and neither the power steering pump then the only thing left that could cause the noise you are having is a dry bearing on one of the pulleys now this could be the alternater pulley or power steering pulley basically any pulley that the belt is running on could be causing you the noise you hear. To stop the noise you need to buy a spray oil or spray lube then give these pulleys a good spray all around where the bearing is in the middle if the bearing gets to dry it can sieze and cause you loads of problems so go and buy a spray lube and give all of the pulleys a good spray at the front and the back try and get it in towards where the bearing is in the middle this should then stop the noise that you are hearing.
you can spray wd40 on the pulleys but remember this isnt a oil or lube it will just stop the noise for a couple of minutes so you could tell witch pulley is causing you the problem your better of buying a proper spray lube and give all the pulleys a spray where the bearing is in the middle this should then solve any noises you hear.
Make sure you check the engine oil level to rule out the noise coming from the inner workings of the engine ok
Let me know how you get on or if you need further assistance ok.
If WD-40 got on belt, and squeak went away for a while, it may just need a new belt. The humming noise sounds like a worn wheel bearing that should be checked and replaced if needed. If squeak goes away when you push slightly on brake pedal, it may be rotor on same side as wheel bearing making the noise due to slight shifting of rotor because of worn bearing.You can try swapping tires on front from one side to other to confirm it isn't tire problem as well. If noise shifts to other side, then it's a tire.
You probably need a new belt, don't buy a cheap belt. I have used cheap before and had noise right away. Ask for a Gates belt. When you sprayed the wd40 it lubed the old belt temporarily so the noise went away. Better to replace all or them at the same time. I am pretty sure the nissan has 2-3 belts.
could be the alternator, water pump take the belt and spin all the pulleys and listen for noise and make sure they turn smoothly another trick is to take a can of wd40 or equivalent and spray the bearings 1 at a time till the noise goes away or quiets down
The best way I have found to locate a belt noise is to take a can of WD40 and spray it on the belt when the engine is running. (be careful of the fan) If the noise goes away, you know that it is a belt noise and not a bearing. When serpentine belts dry out they make funny noises.
Hope this helps, cheers
