If I don't have any symptoms of a faulty timing chain tensioner, at what mileage point should I go ahead and replace the original? I'm an 04 currently at ~37,000 miles.

 

I did my 2006 car at that same mileage as preventive maintenance. Billman's GenX version. 10 minute install once you find the 10mm ratchet

When you have symptoms.

 

I replaced mine as a preventative measure, but did so at about 115k miles. Even then, it was a bit premature. I had no symptoms.

Some would say that was a waste, since it might have been a very long time before any symptoms popped up.

At 37k miles you have nothing to worry about preventative wise here...

 

Thanks all...I guess I won't fix what isn't broken.

 

I've heard of them showing signs that early. I changed mine at like 85k. Bought the car at 75k. Partly misdiagnosed sound and partly peace of mind. Never hurts to do it then you don't have to worry. It's not cheap but it also is really not that expensive.

 

how dose the sound start out i think i hear the ever so slight clicking noise they make, ap1 55k on car

 

Had this conversation with Billman when my 2009 was at 40K miles without symptoms. He said it was not if but when.

Installed the GenX version and have put any worries out of my mind.
