I?d like to start Summerizing my 2005 Volvo Penta 5.0GXi myself and would appreciate some help. I have 4 brass drain plugs that I installed, but I?m wanting to confirm that the brass plugs don?t need anything added to them, rubber washers, Teflon tape, etc., to make a water tight connection? It was fogged in the Fall, so is there anything that needs to be done before starting the engine after fogging? After I connect the hoses and battery, I think I?m ready to go. Any additional advise would help, Thanks.
