Hello, I have replaced the heater hoses twice on my 1990 Cadillac Deville and I am unable to locate one of the serpentine houses. There are 4 black molded heater hoses that connect the engine to the heater. There is on small piece of green serpentine heater hose that connects two pipes below the engine. There is one other 2 piece of serpentine heater hose and I cant figure out where it goes. Does anyone know?

Mike-the pipe which comes out of the under engine hose travels towards the front of the car,bends sideways then follows the engine past the a/c compressor,does a u turn then is attached to the back of[the water pump?].That is where your second small hose is used.You wont be able to see it very well,too much stuff in the way.I know from having replaced these hoses on my 1989 and 1983!
