Hello,
My mechanic and I were wondering if any of the Volvo experts on aq151s might know why there is a freeze plug that blocks the circulation of coolant to the intake manifold. The plug is in the head...the pictures tell the story pretty good.
He suggested that we drill a small hole in the freeze plug to allow the coolant passage to fill with water so air is not captured in in that chamber.
does anyone know why it is blocked and if unplugging it will help this older engine to run better or not.
Thanks in advance....JSOcean
