Author Topic: Chain tensioner question... (Read 2332 times)

Doing a search, I found a picture of what appears to be the timing chain tensioner and it's accessed from the outside. Can I just pull the bolt and replace the tensioner?

Thought this might be a good safety item while working in other things nearby.

The 19mm hex just above the A/C bracket is the tensioner cap. Take that off, and the tensioner resides inside.

Not sure what you mean by "good safety item while working in other things nearby".

Sorry. Should have a little more clear. I was thinking as long as I was in the area of the engine working on things, it would be easy to swap out the tensioner as a preemptive measure until the day I dig into a timing chain,etc redo. I'm guessing I have a 20 year old chain, even if it only has a 142k miles.

I'd hold off until you're sure of the condition of the chain, guide rails and cam sprockets. I've heard of a few cases that putting a new M44 tensioner onto an old timing chain quickly wore the guides out. The guides were revised as well.

I hear ya. Install something new and the surrounding old parts crap out.
