Folk this might be a silly question but the devil is in the details. I took off my dp-sm drive off for engine removal. Now after engine repair has finished i went to install and noticed the water inlet hose harb with a single o ring. The kit that i bought to replace bellows brings 2 o-rings. Also the o-ring was on the second groove close to the back of the hose. On the first groove there is a hole facing up. I read somewhere that it is ment to face downward. I want to do install correctly since this would be my 1st volvo drive. Please enlighten.
