91 Olds Cutlass Ciera timing chain

[bflobrian]

I need a crash course on changing a timing chain for my Olds Cutlass Ciera with a 3.3 engine. Water pump leaks too and I'm sure that will be one of the parts coming off anyways.
Thanks for the help.

Thanks maxwedge for the advice and the greeting, I will give it a try.

Could you help me on a couple of points.
Do I need a special tool to align the crankshaft sensor after installing the timing chain and sprockets?
Also, why align the marks on the sprockets before taking off them when one version says I need a special tool again when tightening the camshaft bolts and after torqueing them to specs add + 105 degs. I'm a bit confused.

Has anybody got an easier way to explain.

Thanks,

Torque the camshaft bolts to spec, add 105 degrees, then line up the sproket markings.... no you dont need a special tool to line up the crank sensor... just put out the extra couple bucks and buy a new one... it's very easy to remove the two bolts holding it on. Your new one will be preset, and ensure reliability.

They mean torque the bolt, as Ian says, then rotate another 105 degrees normally this is done with a torque angle meter as the bolts are torque to yield, you should replace any bolt that is torqued in this manner, they are one time use only.

Do I need the torque angle meter? I know some parts stores let you use tools for the job.
Why line up the sprocket marks and then put the chain on and rotate 105 degs.
Does something happen when you take off the chain?
thanks

ps...I had a long message more detail questions but this website said I wasn't logged on when I was and it was all deleted so I'm trying it faster

you rotate it with the new chain on to ensure everything is done right, if you turn if and it doesn't lock up then you know its good, if you go to turn it and it gets jammed

Ok, I see you are somewhat confused here, the 105 degrees is how you do the final bolt tightening, not the rotation of the cam gear.

[bflobrian]

OK, I think I understand.
I'm not actually rotating the cam 105 degs. but final torqueing the cam bolts.
Is that right.
When all is said and done the marks on the gears should line up ... bottom of cam and top of crank should line with each other.
I also understand rotating the timing chain when all is complete to ensure it is on right and doesn't bind.
Any more questions I'll be sure to write.
Thanks
