Shop completed my winterization last fall, they pulled the old Impeller out and left me a new one hanging on the steering wheel without the directions of installing. Of course they are now out of business.<br />Question is which directions do the spines go? Volvo Penta 5.0. Part number towards the block or towards the impeller housing? <br /><br />I've searched high and low on the net and can't find a answer.
