Timing Chain Tensioner
Just got a new tensioner from CED.
Do you just take the old one out and put the new one in? Or does it need to be tapped and unsprung with the valve cover removed?
I've heard mixed responses, and I'd rather not tank the motor.

Does your new tensioner come apart or is it one piece? If its one piece then you just put it in and you're done. However, I'd recommend taking the valve cover off first so you can make sure the timing chain doesn't skip teeth when you take out the old tensioner

Me too. Hasnt been as long as this, maybe three months. But mine is fine. And the people that posted that this was fine are people who have been around these forums for a long time, and ones I trust.

The new one I bought is the new design from GM. One piece and locked into place with a retainer clip it appears. I've just heard mixed things about putting it in and am kind of paranoid.

They are hydraulic, and with the engine off( no oil pressure ) you shouldn't jump time pulling the old one. New one is pre set from the factory. Just make sure you get the right torque spec for install. I don't remember what it is off the top of my head.

Just take out the old one CAREFULLY and then put in the new one. I say to be careful with the old one, because if it is too far gone, it WILL fall apart and potentially drop pieces into your engine... then you're stuck taking off the oil pan to pick them out.
I changed mine in the parking lot of the CED 2010 meet... then drove the car 300 miles home. Never a problem. There's a picture floating around somewhere on here of my old tensioner in pieces on the asphalt.
EDIT: Found the picture... unless your tensioner is to the point of ticking... I don't know that you'll have this problem.

Normally a stopped engine will be in a position where there should not be too much load on the valvetrain (and so on the chain).
If you want to be safe, just turn the big crank bolt with a spanner to the TDC mark, then just swap the tensionners

that is what you need to do when replacing the old tensioner with the a new tensioner OF THE SAME DESIGN. the tensioner from CED is a little differant, and from what i have done and heard, you do not have to reset anything, i replaced mine 2 days agao and didnt set mine, just had the car out today and no more noises.

i got mine in, and it started up just fine. no weird noises or anything. if it skipped teeth there would be a CEL right? even if it only skipped just one? i guess im being a bit paranoid
you might still have part of your old tensioner in there. mine was a piece of cake to put in
