I bought 3 new chain tensioners for my 1999 Cabriolet. The two that are accessible from beneath the car I replaced. I did not replace the upper one because it is under the AC compressor. I understand the AC compressor needs to be moved to access the tensioner and this is accomplished by removing the 3 compressor bolts. But Bentley says you need to remove the power steering pump reservoir too, which looks messy. I suspect you need to remove the reservoir if you are removing the compressor, which I am not. I just need to shift it over. Can anyone speak from been there done that?
I've got the three chain tensioners sitting on the shelf waiting to change with the oil in few weeks. From the bottom, the IMS (I think) tensioner is the easiest one - totally exposed for a socket. The other one accessible from the bottom is "fenced" by a couple of metal coolant tubes. Can the coolant tubes be temporarily moved out of the way by undoing their straps to gain sufficient access to the tensioner? Or, do the tubes have to come out by decoupling them from their in and out rubber hoses? (I'm trying to avoid cracking open the coolant system...) Does the cam have to be locked in TDC with a pin through the pulley hole? Is there still a chance that any of the three chains could jump a tooth while removing the existing tensioner or putting in the new one? I plan to complete each tensioner completely before moving to the next one (two tensioners will never be out at the same time). Any other tips or tricks? Thanks for any advice.
