Idler Pulley and Tensioner Issue and Later Model Gen 3 H6 3.0?
I have a 2008 H6 3.0 Outback with 75,000 miles.
I've read about the idler pulley and tensioner replacement issue. From what I've read it seems to be very common with Gen 2 Outbacks. I have found a few instances where 2005 model year H6s have had the issue.
Is the failure of these two items common at the tail end of Gen 3 for the H6 models? I am not seeing much talk about it.
Is water pump replacement necessary, or is that more of a H4 issue?
For the 2008 year, I believe the tensioner is Subaru part number 23769AA003 (roughly $80) and the idler pully is 23770AA020 (roughly $35). Water pump is 21110AA360 (roughly $110). I am familiar with the act of just replacing the bearings in the pulleys.
