Nissan Maxima: Timing belt tension adjustment

If you use a nissan belt it's impossible to screw it up as it has marks on
it.

 

To tension the belt before you lock it down. If you just wind up the spring
to get the tensioner back and snug the nut, install the belt, unsnug the
nut and let the spring do it's job then tighten the nut back up it's a done
deal. If you had to work against the spring to adjust the belt, you were
doing it wrong.

 

Exactly..

 

If you used an aftermarket belt with no marks, $20 says you have the rear
cam advanced a tooth, you do realize the marks on the covers aren't quite
right and the marks on the belt are? Seen this done dozens of times and
kills the power the car is supposed to have. To fix it you get to take it
all back apart!

Thanks for the reply Steve.

Yes I used a Nissan OEM belt.
 

So it looks like Nissan FSM has a mistake?! As I pointed in a) I ended
up in 11:30 position according to FSM. That means that spring would
unwinds _from_ the belt no to the belt. Which just doesn't make sense.
 

I used Nissan OEM belt. I agree that by symptoms it looks like one of
the cams is advanced a tooth. But when I installed the belt I didn't
use marks at the rear upper cover - I simply don't have them. I just
matched all the three marks on the belt with dots on the
crank/camshaft sprockets while in TDC1. It should be enough.
May be I have to check it... I hate to undo the whole thing!!!

Btw do you know why do we have to set TDC1 on the compression stroke?
Why not on exhaust stroke? In both cases all the marks line up...

If you're sure all the marks lined up with the marks on the pulleys, you're
fine. Maybe the EFI engine temp sensor is wacky? You were in that area and
if it is corroded, when you disturbed the wires to it you could affect how
it works. Not fun to get to without a special tool. Also replace the
subharness and the sensor if you do this.
 

The cam pulleys wouldn't, they'd be 180 deg out i.e. the dots pointing down.

And yes it sounds like a FSM is wrong if it instructs you to have the
tensioner where the spring pulls the tensioner away from the belt.

I think you mean coolant temperature sensor. I don't think 90+ Maximas
have EFI temp sensor.
 

Yes, looks like you are right. Thanks.

you're 
and 
how 

The coolant temp sensor is up on top. All it does is send the info to your
dash guages. Whether you have it plugged in or not will not affect the
engine performance. Kinda like the oil pressure sending unit. It just
measures something for the human eye to look at but doesn't affect/control
anything.

Just checked in FSM. There are two sensors actually. Engine coolant
temperature sensor (ECTS) sends signal to ECU in order to adjust
engine working mode. Thermal sensor sends signal directly to the
temperature gauge. The two sensors are completely independent.

Whatever you want to call the sensor that the engine computer measures the
engine temp. They change what they call this stuff from year to year, the
parts guy will know what you're talking about. If you call it a "coolant
temperature sensor" they'll sell you the one for the gauge on the dash,
that's why I call it the EFI temp sensor.
