I am looking at a 2010 AR 240 with the 1.8 l engines.

Does anyone have any insight on if these particular generation engine is reliable? I have heard about timing chain issues.

Thanks,
Jim

That's the oil cooler year. Fixable. If you do a search for oil cooler you'll see the issue.

I see that the bolts shear off. Good to know thanks for that info. Easy fix it seems from all the other postings.

I got some pics. I think that along the bottom all 3 bolts are sheared off. Or better yet they come in on the other side.

I’m at about 250 hours on mine with no issues. Changed the oil cooler bolts, regular maintenance and they will last.

I can still do 52 mph on half a tank and two people on board.
