SOURCE: need to install a thermostat of a nissan altima

Dear Guest: If you have some reasonable mechanical aptitude, it is a simple task on this engine to do.
The thermostat is located near the front to the engine (the side closest to the belts) and on the side where the radiator is.
Follow the top radiator hose to the engine and you will have found the thermostat housing.
1. Make sure the engine is cool before doing this job.
2. Get a drain pan and drain the coolant from the radiator. The drain **** for the radiator is located at the bottom of the radiator. Some have an end which can be turned without tools and others require a flat screw driver to unscrew the fitting from the bottom of the radiator. Make sure you remove the radiator cap, as it will drain much faster. Once drained, put the drain **** back into the radiator. Be careful and DO NOT OVER TIGHTEN IT! It will snap off in the radiator!
3. Release the hose clamp which secures the hose to the thermostat housing and then grasp the hose at the neck where the clamp was and try to rotate the hose on the housing. DO NOT try to just pull the hose off. Break it loose first by rotating it on the housing. If it is stuck, get a small screw driver and carefully, slide it in between the hose and the housing, working it around until you can rotate the hose. At that point you can remove the hose and push it off to the side or take it loose at the radiator as well. CAUTION!!!!! the radiator tanks are plastic and will break if you are not careful!
4. There are 3 bolts which retain the housing to the cylinder head.
Typically the bolt head size is a 10mm. Using a 10mm socket, rotate the bolts in a counter clockwise direction, removing all three bolts. There are some that did use a 12 mm bolt head size. Most of the time the housing will just come loose. Sometimes, it will stick. If so, a light tap will break it loose. Pay attention as to how the thermostat is positioned in the cylinder head prior to removing it. Most of the time it will pop out easily or you can easily pry it out with a small screw driver. CAUTION!!!!
Do not damage the mating surface where the gasket seals.
Carefully clean the old gasket off. A single edge razor works fine.
5. The thermostat has a top and a bottom. If you look closely, you will see a place in the outer parameter of the thermostat where there is a small hole, often with a little metal tab which projects through the other side and is able to jiggle some. This is a small bleeder to help bleed the air trapped in the system when it is installed. This part of the thermostat must be at the 12:00 position.
Additionally, make sure the part with the hoop is sticking out toward you. The cylinder head has been machined to allow the thermostat to fit flush with it when installed properly.
6. Clean the old gasket from the thermostat housing. Nissan utilizes a liquid gasket sealer (silicon) which you apply a "SMALL" bead around the water inlet (the cylinder head side), let the sealer skin lightly and then put the housing in place making sure that the thermostat had remained seated during the installation. If it had come loose and you try to tighten the bolts, you will crack the thermostat housing.
7. When you tighten the thermostat housing bolts, there is a torque specification however most people don't have torque wrenches which measure in inch pounds. For those who have a torque wrench, 10mm bolts:56.4-66 inch lbs, 12mm bolts 12-14 ft lbs.
I have found that the easiest way to keep from over tightening the bolts is to grab the ratchet from the head and tighten the bolts because you don't have the leverage at that point.
8. Let the silicon dry for 10 minutes and and then fill the system back up with coolant. Reattach the hose and clamp being careful not to over tighten the hose clamp.
If you are replacing it, not more than a 50/50 mix. There is no special bleeding procedure Nissan has for this car. Just fill the radiator with coolant, turn the heater inside the car to the heat position to allow coolant flow into it as well, because it too is part of the cooling system in terms of coolant capacity. I usually fill the radiator until it shows 1/2 way up the tank. As the engine warms up,prior to the thermostat opening, more often than not, the coolant level will rise dramatically before it drops. Once the thermostats has opened top the system off, put the cap on and let it run for a while and watch for leaks. Take the car on a short loop and then recheck for leaks again. If everything has gone well, the temperature will read normal and no coolant will be leaking.
Hopefully this should be sufficient to answer your question.

SOURCE: CRANK SHAFT POSITION SENSOR 20002 NISSAN ALTIMA

1st, Nissan had a recall on Crank position sensors for 2002-2006 Altima's. Check with you dealer before you go doing any repairs. You may discover you can get your car repaired at no charge.
NHTSA Campaign ID number :O7V527000
Symptom: Erratic behavior. Stalling and no starts and very difficult to diagnose due to the time frame in which the component actually malfunctions. The warranty should not be limited to the original owner.
I would also need more specifics as to which engine you have so I might assist you in where the location of the sensor is. The Altima had a 4 and a 6 cyl engine offered that year.

SOURCE: high idle stalls at lights code for crank sensor

Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:

  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit

On my 2003 nissan altima trying to figure out were the MAP sensor located.Can you help me plze?


There is no MAP (Manifold Absolute Pressure) sensor in a 2002 or later altima. This altima uses a MAF (Mass Airflow Sensor). It is in the intake and has a clip with 5 prongs. God-Bless!

Hi!!I have a code on my 2003 nissan altima it reads p0107.I've changed the mfs its loosing power.Any suggestions?


code p0107 refers to manifold absolute pressure (MAP) sensor/barometric pressure (BARO) sensor--low input===causes wiring short to ground.---MAP sensor---Baro sensor----ECM
Maybe you didn't change the right sensor.

MAP SENSOR


The MAP sensor is located on the driver's side of the engine compartment next to the air filter housing and shock tower.
It is a small plastic component with one vacuum hose coming off of it and an electrical connector that has two wires. . Sometimes just replacing the part is a waste of money. The fact that the code has indicated the problem is the MAP sensor, doesn't mean it is bad. As an example, check to see if the Vacuum hose is secure and not disconnected or split at either end.
Good luck.Here's what it looks like.

Where is the crankshaft and camshaft sensor located?


Here's some pics of my 2003 Altima Crankshaft Sensor. Often mistaken by the Camshaft Sensor because both are identical sensors. They are each located in different locations. I've seen diagrams with the WRONG labeling. Again, this is so confusing for even a mechanic to understand because both sensors carry the same part number which is rare. http://x.nissanhelp.com/forums/members/digitaldxing-albums-2003-nissan-altima-crankshaft-position-sensor-picture331-2003-nissan-altima-crankshaft-position-sensor.html

Where is located tps in altima 97


1997 Nissan/Datsun Altima 2.4L SFI DOHC 4cyl: the Throttle Position (TP) sensor is a potentiometer. It is mounted on the side of the throttle body and is connected to the throttle plate shaft. The sensor monitors throttle plate movement and position, and transmits an appropriate electrical signal to the ECM. These signals are used by the ECM to adjust the air/fuel mixture and spark timing according to engine load. The TP sensor is adjustable on some models.
Automatic transaxle/transmission TP sensors contain position switches. These switches provide a signal to the ECM when the engine is at idle and wide open throttle.

Hope helps (remmeber to rate and comment this).

Location of maf sensor in 2005 Nissan Altima


It's a MAP (Manifold Absolute Pressure) sensor. Go to Checker, or NAPA, or PEP Boys and look at the replacement part - then you can find it under the hood. Probably mounted on the firewall. First check visually for a vacuum hose that may have fallen off (or split) on or near the MAP sensor.

1999 Nissan Altima MAP sensor location


The MAP sensor is located on the driver's side of the engine compartment next to the air filter housing and shock tower.
It is a small plastic component with one vacuum hose coming off of it and an electrical connector that has two wires. It might be advantageous to write in and let me and/or other techs know what the symptoms are prior to replacing the sensor. Sometimes just replacing the part is a waste of money. The fact that the code has indicated the problem is the MAP sensor, doesn't mean it is bad. As an example, check to see if the Vacuum hose is secure and not disconnected or split at either end.
Good luck.
