SOURCE: replacement of a head gasket on 2.5 liter nissan altima 2002

frajogag: First off, be aware that these bolts are "torque to yield" bolts (streach bolts). What this means is that instead of torqueing the head bolts to a specific torque specification, they are torqued down to a set spec and then tightened by rotating the bolts a certain angle, like 90 degrees. and all of them are turned the same amount.
This means that the shanks of the bolts must be checked to make sure they are not too thin (or the bolt has already stretched beyond limits and is prone to snap if used)
Here is how you check the bolts. Measure the bolt using a micrometer, at the base, or within the first 13mm from the end where it threads in. Then go to about 10mm before the threads end heading toward the top of the bolt. There should not be more than a 0.23mm (.0091 inch) or less difference or the bolt should be discarded.
Torque the bolts down to 98.1Nm ( 72.ft lb)
Looking at the head from the side, so you are looking at the full length from side to side, I will number the head bolts in this fashion.
#1 & 2 are directly in front of you and in the center of the cylinder head crossing it width wise.
#3&4 are to the left of #1&2, / #5&6 are to the right of #1&2
#7&8 are to the left of #3&4 / #9$10 are to the right of #5&6
Now, you have the sequence.
After the initial pull, back off all the bolts in the same sequence and then retorque them to 36 Nm ( 28 ft lb)
Using a torque angle wrench or having the ability to accurately judge turning angles. Rotate (clockwise) to a 75 degree angle. do this to all the bolts using the sequence I had provided.
Rotate the bolts (clockwise) 75 degrees again on all bolts in the same sequence. The proceedure is complete!

How do i change the timing belt on a nissan altima 2001


A Nissan ultima does not have a timing belt,it has a timing chain,look up in your manual for your maintenance schedules when and at what mileage you are needed to change the chain,usually the chain is changed when it is loose through stretching in wear over mileage,a very loose chain has a rattling noise in the engine compartment by the cam gears,good luck ,hope that I was helpful.

remove the front bumber cover, that will show you an extra bolt at the bottom of the head light which you can not see with the bumber on. if you press down hard enough you could stick an extention with a 10 ml socket so you can remove the bolt without removing the bumber cover.
