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
