TIMING BELT INSPECTION

It`s dry. Not too tight...
(I`m absolutely sure it was done right, appr 25k ago.)

OK?

Looks good!

Should be about like that with engine cold, a little more taut with engine warm.

Thanks a lot!

I took a new timing belt video because I was working on the power steering today.

Since I was already there with the steering stuff removed and with plenty of space available, I had to look around...
I inspected under the cover, cleaned the inside of the tb cover, it is all dry in there (no oil stains at all) but (when I had an exhaust leak under that ugly stup.d EGR mushroom--- it is removed and got blocked off since) some blck dust got in a little at the edges through the sealed gaps.

The idler `roller` doesn`t jerk around, the waterpump does have a tiny little minimal play as I grab the teeth to try to rock it. Really not much. The belt isn`t stained, I don`t see `dry rot` or weird looking edges or teeth.

I do know that they have to be somewhat `loose` but every time I saw/see mine, it makes me wonder: isn`t it on the loose side a little bit?
The engine BTW was cold at the time of recording this video.

Not just the tightness, also the structural&chemical integrity at this point. So far I have driven ~35.000 miles on the timing belt that was installed by the PO, *perhaps* in the same year when I got the car 8y ago. (If you wonder, yes, car is in regular use but mostly for longer trips only.)

Before I bought it, as far as I remember it got ``refurbed`` and driven for a few months on longer trips so that is X plus my 35k. I cant remember what the odometer mileage may have been at the time of that initial refurb. Currently it has 440500-441000. I`ll check what exactly it shows (and on top of all those miles there was a few months worth of driving which is extra miles because the cluster had been taken out once due to ignition switch wires and other dash wiring updates).

Belt tension looks good judging by your last photo. Should be able to twist the belt there ~45deg using thumb and forefinger, cold engine.

45 on both 'sides' ?

There's a video too it helps you to imagine the slack.
