long flat head
new timing chain tensioner http://www.crateenginedepot.com/stor...P2216C133.aspx

lets start shall we
ok first off go to the trunk and disconnect your battery the postive is a 8mm. now head to the engine bay.remove the plastice ecotec supercharge thing a mow bob. then there's a hose that connect to the back of the valve cover, grab some pliers squeeze it and move it back. letting you remove the hose from the valve cover. now if u follow the hose there a metal thing that holds the hose up above the engine. its a 13mm bolt on the first one and the seconde one is 13mm nut. so make sure u hang on to them so they dont drop. next there is a bolt that holds your fuel line down. it's on the right side of the engine if your looking right at your engine. that's a 10mm. the resone why u have to remove this is beacuse there are 2 valve cover bolts that are under that, so if u remove this bolt it will let u move the fuel rail out of the way. next step is to remove the middle metal piece that hides your spark plugs. i have no idea what kind of a tool that things it called but it looks like a star fitting. once you remove that frame there 1 10mm bolt on each plug u have remove. so remove those and you should be able to remove the plugs. then there four 10mm bolts that are connect to the head that you have to remove. now strectch out your back and start removing the valve cover bolts. they are 10mm and i beilve theres 10 of them. heres a pic of all the holes.

now remove the valve cover, its a little stiff i used a flat head to remove it. now it should look like this.

now there a 32mm hex bolt on the very back.if u stand on the passenger side, put your hand on the backside of the engine go about half way down and u will feel a big bolt. this is what it looks like with it removed, the big hole. sorry no flash battery was low.

this picture was sent from a dealership. it shows a better picture of where the holes is. but this mostly explains how to rest the piston. no special tool os required, i used a flat head a the tool to remove the snap ring pretty easy!

k now grab the new chain tensior. and this is a tricky part for me. i ended up resting the piston 3 times. here the trick grab the tesioner and place it in the hole. then you put the 32mm socket on it.....NOW put as much pressure as u can pushing to the engine and start ratchiting. now if u fell it spring it out just keep going, this means it just set in its normal way to put tension on the chain. so when u think you have gotten it. stop putting pressure to it and if its stays congrats you just replaced it. if not im pretty sure it just sprung out so reload it. how u reload it is. there a snap ring on the other side of the threads. snap that out and then pull it apart. then u will see a grove that a flat head will fit in. turn it clockwise and then it will begin to be compressed and then lock. now tighten it all the way up and if u look at this picture u will see a yellow looking thing.below the sprocket. hard to see!!!!

i grabed a long flat head and gave it a little smack to set it. i really dont think it matters if ya hit it or not cause when i was messen around with this part i could let it spring out with out hitting it, by just sqeezing the prong low enough. so thats pretty much it. o for safety you can put RTV sealent on the valve cover but i didnt, i just wiped the gasket and then sprayed a little brake fluid on a rag and just put it on the head. so now just start putting everything back together. i beleve its 74lb tourqed. but i just tightened it enough to where i thought it was good.look for leaks after start up............. if anyone else has something to add please do so!!!!and if u find words or sentenses that sound wierd....ya i suck at spelling lol sorry.....:boohoo:

 

Approved. I have a feeling others will chime in.

 

ya im sure others well...if u build it they will come!lol

sweet mine ticks like crazy (chain not the tensioner) iv been wanting to do this but have been scared thanks alot for the how to iv been looking for for ever

 

Approved very nice how-to

 

thanks u very much

 

any chance for better pics? the first 2 are great but the ones we really need r too fuzzy.

 

no since i got it back together. thats pretty much all the pics u need. the first one really isnt that fuzzy. it show the hole. the 2nd one ill agrey its very fuzzy. but even for me to look down the chain to get a pic of the plastic thing was hard. if u get a haynes manual it will show u how....

 

I'd love to know why the how-to I did on this MONTHS AGO didn't get posted.

 

Send a message to a mod next time. Not many of us even look at the how to's to see which one's need to be approved. Honestly it's a waste of time, since we don't get paid to be moderators.

 

Nice. I need to do this soon.

 

still no problems with mine still.

 

First off THANK YOU for posting this up. It helped me muster the ***** to take this on. lol

In doing this though, I discovered that the updated part doesn't require any of the steps listed in alldata, the dealer, etc. It is completely plug and play without even needing to remove the valve cover. Just unscrew the old one and insert the new one.

Tools used doing it this way: 1 1/4" or 32mm socket (same as oil filter), ratchet, and a torque wrench to properly torque it down.

 

humm i didnt now it was a plug and play deal......so the tech said that?

 

this is very helpfull man thanks!

 

Actually I did this myself, no tech, but I did have access to alldata. The instructions you'll find everywhere are for the old version of this part, which comes as two pieces and requires a special Kent tool to assemble it.

The reason it is plug and play is because the revised part is already completely assembled. There is no 'setting' that you have to do once its installed, which is the reason you would normally have to take the valve cover off.

I have about 5000 miles on the new tensioner and it is running fine.

 

no problem

hummm. i guess it kind of makes since. cause when i was looking at it i pressed on it, maybe 5 pound of pressure and the sob just shot out lol

 

Sub.

Nice write up, i need to do this at some point...maybe this fall.

 

ill have to get it done, confusing but hopefully i can manage

 

good right up.

 

click, good info

 

how hard was it to get loose and what did you use besides the socket and ratchet because I am having a real hard time breaking it loose

 

stupid question here i guess, but why do you do this and what signs are there to say hey, you need to do this? thx for the info.

 

if you all of a sudden start hear a your engine ticking, u need to replace it. it could cause damage but i've havent seen anything yet. but its just something that u dont want to wait on.
