Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hello, still having to figure a way out to remove the front of engine timing tensioner from under AC compressor. Is it possible to remove the IMS bearing without having to release the front timing belt tensioner? removed bottom and side one but the one under the A/C compressor is hard because we are haing a hard time to remove the compressor third bolt in back of it. this bolt has been holding us up for days now. If we need to remove, anyone found a good way?] ​​​​2000 996 Carrera 2, Cabriolet.

I believe it's not as big a deal on the 5 chain motors. I've done mine three times, only once did i pull the third tensioner.

POST 3Original post

Its a crap shoot, sometime you can get away without and sometimes not, you will know once you remove the bearing if you need to or not if the shaft stayed centered.

POST 4Original post

You can remove the back AC Compressor bolt using a 13 mm swivel socket and a 6” extension by going thru the hole in the intake where the air temp sensor is mounted. I use a mirror to look into that are to see the socket and guide it onto the bolt. First time is the hardest (took me 3 hrs). Now I can do it in 5 min., practice makes perfect. Mark

What reason did you find that you needed to pull out on the last time?

Figuring out how to reach and location of bolt has been main issue for is. Engine is still in car and all AC hoses I want to keep intact to avoid having to re do ac pressurization

Would it slide off guides in this side of engine? Is been weeks since we took other tensioner of but this one on top eludes is.

How. The compressor comes off with 4 bolts, all r accessable without removing the hoses. Just swing it out of the way and remove it if needed. Sometimes the front chain will pull on the shaft and sometimes its just the rear of engine timing gear itself needs to be rotated back some to center the shaft.

POST 9 / ORIGINAL POSTEROriginal post

Do you mean if we don't remove the front tensioner it could throw out timing of IMS to cam chains on rear of engine? I dont want to screw up timing as I have not played with those parts yet and would need to educate myself on how to fix. so do you recommend to remove 3rd tensioner to lessen the chance of throwing timing off?

POST 10Original post

No im saying the front tensioner can "pull" the shaft to one side. If there is tension on the bearing it will be harder to remove and impossible to install a new one. The shaft needs to be centered. if the cams r locked timing can not jump. my comment in response to the front tensioner "eluding u". Its easy to get to (if needed) u just lift the compessor out of the way.
