BMW: at tranny cooling lines 2 OR 3, vehicle id number, bmw 325i

Question
I RECENTLY BOUGHT 2 AT COOLONIG LINES FOR MY 87 BMW 325I SEDAN THEY WORKED PERFECT BUT NOW THE MECHANIC SAYS THAT THERE'S A THIRD HOSE FOR THE INLET PIPE, HOW TRUE IS THIS? AND CAN YOU RECOMMEND ANY SITE TO FIND IT AND RUSH DELIVER IT.
THANX FOR THE HELP I APPRECIATE IT!!!!

Answer
It really depends on the vehicle. My parts catalogue shows either way, 2 or 3 lines depending on the vehicle id number. If I had that information I could better answer your question. Best bet would be to call you nearest B.M.W. dealership and give them the vin # and ask them how many it comes with.
