I looked in how to and diys can't find anything on how to do a timing chain tensioner
Hi Coby; I'm going to be looking at the tensioner on this Cobalt I bought my son tomorrow and I may just go ahead and replace it since I'll have the valve cover off anyway (oil leaking around the cover). Does the tensioner get mounted near the top of the engine? I wish there were some pictures available of this process. I'm surprised no one has done a DIY for this job... Can't seem to find any YT videos either.I think OP only wants to change the tensioner for the revised version. This is a fairly simple job if the old tensioner hasn't fallen apart. You take the valve cover off, tightly zip tie the chain to the cam gears. The next step is where you might need a third hand if the tensioner has fallen apart like they often do. My 08 had fallen apart, so you have to apply pressure on the plastic guide opposite the tensioner as you unscrew it so no parts fall inside the chain cover. If your lucky enough and it hasn't come apart like my 07 it will come right out intact. Then just screw in the new one in, torque to spec and tap the guide to release the tensioner plunger, remove zip-ties and re-install cover and you should be good to go.
It's near the top left of the engine, it's a 32mm head jutting out the back of the engine.Hi Coby; I'm going to be looking at the tensioner on this Cobalt I bought my son tomorrow and I may just go ahead and replace it since I'll have the valve cover off anyway (oil leaking around the cover).

Thanks in advance for the assistance.
I see now... Thanks very much!It's near the top left of the engine, it's a 32mm head jutting out the back of the engine
Went very easily. I got the old one out, and it was the old style with the spring. It looked fairly warn, but was not broken. The new one went in without a hitch.I see now... Thanks very much!
Yeah, this should be an easy one. So, if the head on the tensioner has a bump on it, it's the new style tensioner, but I really still don't know how long it's been installed. The car is at 176K and it's been maintained fairly well. Tomorrow will be the first opportunity for me to really take a look at it..
Cold starts are silent currently, but for the 35 bucks the tensioner costs, and since I'll be in there anyway, I'm thinking it'll be good peace of mind..
