I am replacing my timing belt. First I put the engine at top dead center for cylinder 1. Then I marked the positions of the crankshaft cog and the camshaft cog with paint and removed the old belt. However, when I go to put the new belt on, the white lines on the belt that are supposed to line up with the factory markings on the camshaft cog and the crankshaft cog do not line up precisely. Additionally the belt seems to be a little loose on the side without the tensioner pulley so it can’t be tightened with the tensioner pulley.

The white lines on the belts would appear to line up with the cog markings if I rotated the crankshaft cog one tooth clockwise, but if I did that then the lines I painted on the cogs before I removed the old belt would no longer line up. What is more important to line up? The white lines on the belt with the factory markings on the cogs? or the marks I painted on the cogs indicating their positions with respect to the block before I removed the old belt?

Timing Belt

The factory marks are the most important. However you know the old belt was on correctly and the engine was running as it should. You also did the right thing by marking the belt before you took it off. Mark the new belt using the marks from the old belt. Install the new belt using the marks you just put on the new belt and it will be exactly the way the old one came off. And once you release the tensioner it will all line up the way it should.

Next rotate the engine a few times and check that the factory marks line up. The belt may seem off or loose until the tensioner is tightened against the belt.

How to adjust the timing out of the distributor.

5 Deg BTDC setting at idle (about 650 – 850 rpm) with vacuum hose to distributor plugged.
When it is hooked up again should run at about 10-12 deg. BTDC

TIP

Also make sure that the weights inside the distributor are working freely. And that vacuum canister on side of distributor is working OK. These are prone to split diaphragms on these. You will go nuts trying to tune it.

Performance

On any engine I am looking to get the top performance out of, I advance the distributor until the engine pings and then back it off just a bit. I do this at 3,000 rpm. The higher the octane the more advanced you will be able to obtain.

1998 Nissan Sentra no start and stalls

Nissan Sentra

My car starting acting up last night. It will turn but not start and when it starts it immediately stalls right after.

the next time the engine will not start you may want to see what it is not getting. Either loss of spark or fuel or both. A quick test would be a shot of starting fluid.

Is the check engine light on? Post the codes they might give us a clue.

If I had to guess, it would be a vacuum leak. Try giving it a little gas pedal the next time you try to start it and see if it starts easier.

Can this be solved by a home mechanic or is this a dealership fix

Being a skilled mechanic you would have already dove in using a meter and scan tool. If you feel confident in tackling the job, go for it. Otherwise a shop would be the direction to go. Only you know your own skill level.

Code P0126 – Insufficient Coolant Temperature

P0126 Description

The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.

Possible Causes
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty Engine Coolant Temperature (ECT) sensor
  • Engine Coolant Temperature (ECT) sensor harness is open or shorted
  • Engine Coolant Temperature (ECT) sensor electrical circuit poor connection

Nissan Altima

Should I have a transmission fluid flush on my 2008 Nissan Altima?
It has 76500 miles on it or 123000 km.
Is it safe to have this done or will it ruin the car?
I’ve been reading conflicting information on the internet.
Thanks

Should I change my Transmission Fluid?

Manufacturer Recommended Service – Automatic CVT Transaxle Fluid

  • Inspect every 15,000 miles

There is no mention of changing the fluid in the manufacturers maintenance schedule. Though it only goes out to 120,000 miles.

A little more digging into the subject lead me to a TSB ( Technical Service Bulletin) put out by the manufacturer regarding special transmission fluid April 28, 2008. In short it will void any chance of warranty if you use the wrong transmission fluid(or can’t prove you did).

It would be my personal recommendation not to have the fluid changed unless otherwise advised by a Nissan Manufacturer Dealer.

TSB# NTB08-049

NISSAN; Special automatic transmission fluid requirement

Applied Vehicles: 2004 to current Nissan vehicles

Service Information

If Warranty repairs are being done on a transmission listed in the chart below, the listed fluid must be used. A claim to Nissan for warranty, service contract, or goodwill repairs to the transmissions listed below may be denied if Genuine Nissan ATF/CVT fluid is not used as specified by the part # in this bulletin.

If Customer Pay service or repair of the transmissions listed below is done, the fluid type listed in the chart below must be used. Nissan recommends the Genuine Nissan ATF/CVT fluid part # listed below be used.

Is this a good buy? 91 Nissan 240sx fastback

1991-nissan-240sx

I plan on buying a 91 240sx, but the issue that the car has is that its ignition timing is off; meaning that it does not run. Also in has 195,000 miles on it. I want this as my project car. Is this a good buy? And what should I expect from a car with 195k miles of that age?

Well, you asked if this was a good buy? Though to answer without the price. If the price is $10,000 then NO, not a good buy. If the price is under $500 and the body is perfect, it is an OK buy considering the unknown factor of the engine and transmission possibly being blown. With it not running there is an infinite number of issues that may be present. And with it setting around from not being running, you may be looking at even more failing parts such as rusted brake and fuel lines, etc.

My recommendation would be to look for one that is already running. It may cost you a little more up front but will be cheaper and less work in the long run.

Nissan Code P0101 Mass Air Flow Sensor

Nissan Versa

My 2012 Nissan Versa currently has issues accelerating and when I make a stop the car refuses to move again. The code p0101 showed up so I tried cleaning the mass airflow filter, but I’ve seen very little improvement after a day. What are the next steps I should take to fix the issue?

Nissan Code P0101

Mass or Volume Air Flow Sensor ‘A’ Circuit Range/Performance

Code P0101 Description

The mass air flow sensor (1) is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The more air, the greater the heat loss.

2012 Nissan MAF Sensor

Therefore, the electric current supplied to the hot wire is changed to maintain the temperature of the hot wire as air flow increases. The ECM detects the air flow by means of current change.

Nissan Code P0101 Possible Causes

A) A High Voltage from the sensor is sent to the ECM under light load driving conditions

  • Harness or connectors (Mass air flow sensor circuit is open or shorted.)
  • Mass air flow sensor
  • EVAP control system pressure sensor
  • Intake air temperature sensor

B) A Low Voltage from the sensor is sent to the ECM under Heavy load driving conditions

  • Harness or connectors (Mass air flow sensor circuit is open or shorted.)
  • Intake air leaks
  • Mass air flow sensor
  • EVAP control system pressure sensor
  • Intake air temperature sensor

Slow acceleration with louder engine noise 2016 Nissan Pathfinder

2016 Nissan Pathfinder

Automatic, very slow acceleration especially after a stop. Louder engine noise. Accelerates quite slow period. Clanking noise and bounce when shifting into park or reverse.

Is the check engine light illuminated?

My first guess would be that the transmission is not shifting correctly and is starting out in 2nd gear after a stop. This would also account for the engine having to work harder to accelerate  that may attribute to the louder engine noise. A check engine light code might guide us in the right direction.

Poor fuel mileage Nissan Moco 2007

I’m getting low gas mileage. We recently changed the air filter. Then cleaned o2 sensor, throttle body, spark plugs, and catalytic converter. The engine is in good condition. Average mileage is near 9.7

First Step

The first thing to do would be to see if there are any check engine light codes present. Next post the codes below and we can determine which codes may be effecting your fuel mileage.

What kind of mileage were you used to getting? Is this why you started throwing new parts at it and cleaning everything?

Have you tried fuel from a different station to see if there was a difference?

Possible causes

If you are letting the car warm up before driving it will decrease. Low tire pressure will also decrease fuel mileage. A clogged air filter or dragging brake caliper will also decrease fuel mileage.

Low beam bulb went out again 2006 Nissan Altima 2.4l engine

Nissan Altima

A month ago my low beam bulb(right side) went out, I changed it, everything worked perfect. Here i am a month later ,replacing it once again, except this time the new bulb isn’t coming on.

What could be causing this?
Left side works perfectly fine.

You can swap the left side (good) bulb to the right in order to test if it is the socket. Alternatively you can in stall the newly purchased bulb into the left side to see if the New bulb is bad. It happens.

In most cases the issue is caused from moisture getting into the headlight assembly either from damage or age.
