Would this fit a 2009 gmc sierra 5.3l 1500? o'reilly's show this part number as a fit, but amazon says that it doesn't, so, am confused.

Amazon was wrong on my 2007 Chev Suburban 1500 5.3 Flex Fuel. They showed a fit for me and it was not. The one you show is a two-bolt bracket. Check your bracket. The one on my Suburban is a three-bolt bracket. If you look closely you should be able to see if there is another bolt on the lower left (from the view shown here it would be out of sight and what threw me). If it is not there on your vehicle then I would believe O'Reilly's and it should fit fine.

Can be used this part with volvo penta 4.3gl?

I am wondering why it cant be used on a volvo penta 4.3 gl. It is a gm motor and they use gm parts on this motor. It looks identical to the one thats on my 4.3. Does anyone kno what id different about this one???

I only see fitment for two bolts?it calls for 3 bolts

Important Information: This Tensioner With (2)Two Holes Is A Direct Replacement For The Earlier GM V8 4.8L, 5.3L, 6.0L Engines With (3)Three Hole Mounting Tensioner GM Superseded The Three Bolts With Two Bolts Tensioner This procedure is referenced in Dealer Bulletin ACC08-035. & Crate Engine/Dress-Up Parts in Bulletin GMP09-200 The Third Mounting Hole Was Eliminated In The New Design Due To Unnecessary Stress Load On The Water Pump. (DISREGARD UNUSED THIRD BOLT) when mounting the Replacement 12609719 Two Hole Tensioner

Does this include the pulley ??

This is the complete tensioner pulley. The idler pulley is a seperate part.

It doesn't actually matter if the original has 2 or 3 holes

Doesn't matter if the idler pulley you removed has 3 mounting holes. Mine did and I still installed this one, just threaded in the extra bolt and torqued it to spec the same. They are otherwise identical aside from the extra mounting hole. If your water pump has ever been replaced, then you actually have no way of knowing if your truck originally had 2 or 3 mounting holes.Just install this and don't worry about it.

Just like the factory one.

Worked perfectly, make sure you check if you need this 2 bolt one or a 3 bolt. I got this as a warehouse deal because it was shipped and opened by someone that probably didn't check. Very easy to change.
