Re: help a marine out!!! switching from an aq130d to an aq140?
Glad to hear you are safe at home. I do not know that particular engine, but I do have one of the other Volvos an AQ 131. If it was my engine I would look at ways to by-pass that oil cooler, IMO it is not required. These engines are old technology, probably at least 15 years old. IMO todays oils especially synthetic can handle the higher temperatures and a cooler is not required. That is what I would do if it was my engine. My AQ 131 does not have an oil cooler. Get rid of the cooler and run synthetic, you should be fine.
Another option is to try and get your cooler repaired. But I would first try and bypass it.
Just my opinion, I am sure others will chime in.
Have a great day,
Rob.
