MK is right. The bearing is bad and letting the fan blades hit the shroud. You have to replace the whole assembly.

HEY WHATS UP BRO this is what you have to do i just got brand new headlight replacements for my 05 nissan altima and it looks great by the way if you replace one you should just do both becasue it will look weird. anyways i have an hid kit as well but so. what you have to do is remove the bumper take all the plastic screw things off the top and on the botton underneith the bumber then you remove 2 screws on each side of the bumper they are located kinda in the dender well then you unscrew those then you can pretty much pull the bumper off there are 4 screws holding on each headlight 2 on top one on the side and one on the bottom front in order to remove the headlight you have to take off the bumper. hope this helps oh ya and buy buy the way you should get an hid kit the bulbe size for the altima is an h1 bulb and you need to get the single beam buld. get it at xenoneyes.com and the the 6000k. The 6000k look the best and is the brightest trust me you wont be let down they are brighter and last longer than the standard halogen bulb um also and like 5 times brighter. they are 129$ at xenoneyes.com thats the cheapest price that i have seen and they are a great value and good quality just dont touch the bulb. oh ya if you replace one headlight do both it looks much better. maybe try this web site to show you a little bit of how to do it

SOURCE: Location of oil filter on Nissan Altima 2005

The oil filter is located behind the right (passenger) inner fender cover. It is right next to the crankshaft pulley at the bottom of the front of the engine facing toward the right front wheel. I do not have a picture at this time.

Hope this is helpful!

SOURCE: head light 2005 altima

you have to remove the bulbs from inside of the hood in the engine compartment. in some cars you have to remove some "pins' and remove the entire headlight assembly.. You then remove the holder where the lightbulb is located and replace the bulb.

SOURCE: Nissan Altima no cool air blowing or hot air blowing

Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.

SOURCE: receiving engine code p0420 on my 2005 altima 2.5 s

A p0420 code indicates a Catalytic System efficiency failure, Bank 1.
Basically, the computer is seeing reduced efficiency of the catalytic converter or one of it's components (such as an 02 sensor)

There may be a few root causes, such as a faulty oxygen sensor, faulty coolant temperature sensor, faulty converter, Large exhaust leak, or retarded (slow) timing.

1995 nissan altima se fans not working


If you mean the cooling fan on the radiator, the computer grounds the fan relay when the fan is needed. If the engine temp reaches 220 degrees or you turn on the ac and the fan does not come on, check the relay first.

The fan on my nissan altima 01 always comes on after I shut my car off... my buddy just replaced the radiator and now the fan does not turn on after i turn the car off??? what should I do??


Hello, that is normal for the cooling fans to run after the engine has been shut off, its still bringing the cooling system to normal. If the fans run continuously, check the fan relay fuse.

Temperature level spiking when accelerating


sounds like your thermostat may be stuck shut, blocking the flow of coolant through your engine block. it cools down again because of the cool air coming through the rad.

My 2005 Nissan cuts off and will not start until the engine cools


I would try getting an active diagnostic scan done on the vehicle but it sounds like it has something to do with the ignition system possibly an ignition control module or another sensor.

My 2005 Nissan Altima loss power while I was driving down the street, the next day it cut off at a light, it takes a few seconds to start, but always starts


the 2.5 altima's had a recall on that problem about 2-3 years ago. Go to edmunds or progressive find the recall letter and the dealer will fix it free. well here you go:

section_opened.gif Recall ID # 07V527000 - ENGINE AND ENGINE COOLING Recall Date: NOV 14, 2007 Component: ENGINE AND ENGINE COOLING Model Affected: ALTIMA Potential Units Affected: 653910 Recall Details Recall Date: NOV 14, 2007

Model Affected: 2005 NISSAN ALTIMA

Summary: ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A 2.5L ENGINE, THE CRANKSHAFT POSITION SENSOR CAN OVERHEAT CAUSING A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR.

Consequence: IF THE INTERRUPTION IN THE SIGNAL FROM THE CRANKSHAFT POSITION SENSOR IS SO BRIEF THAT THE ELECTRONIC CONTROL MODULE (ECM) LOGIC DOES NOT HAVE TIME TO DIAGNOSE THE CONDITION, THE ENGINE MAY STOP RUNNING WITHOUT WARNING WHILE THE VEHICLE IS DRIVEN AT A LOW SPEED INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPROGRAM THE ECM FREE OF CHARGE. CERTAIN MY 2006 ALTIMAS WHICH HAVE BEEN PREVIOUSLY REMEDIED UNDER RECALL CAMPAIGN 06V223 (NISSAN R0606) ARE NOT INCLUDED IN THIS RECALL SINCE THE REPROGRAMMING FOR 06V223 ALSO INCLUDED THIS REPROGRAMMING. THE RECALL BEGAN ON DECEMBER 31, 2007. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

Potential Units Affected: 653910

2003 Nissan Altima, Air condition makes loud noise when the unit is turn on. It slows down where u cant almost hear it after you turn the fan off.


When you put your A/C on, there is Vacum Motor or Solonoide, that increases RPM of the Engine to compensate the load of an A/C. If the vacum hose is leaking or raptured the RPM of Engine remain low and Engine Shakes. When you put the A/C on and the RPM of Engine Increases, but a little, then your Selonoide is working but not adjusted properly, so adjust it for the proper RPM of the Engine. Put all the loads on, I mean Head Lights and A/C on and then ajust the RPM.
