Re: Changing oil on a volvo aq290 V8
The oil is removed thru the dipstick tube. I use a vacuum system, works well, got it at Tractor Supply Company. I have never used an electric system but I believe there are ones out there that work well also. Marine dealers will have them, may be a bit pricey there but usually good quality.
It is a good thing to change the outdrive oil each season if for no other reason than to check for water intrusion.
My photo hosting site evidently is down right now or I would post a pic of the vac system I use.
