Hi, I am new here and have a few questions. I drive a 2002 Grand Prix GT. I has 100K on it and was going fine until this weekend. I stop at home and saw white smoke under the hood. I check for a bad water pump or broken hoses and found none. So I start to check for a blown head gasket. I removed the top intake and started on the Lower part when I see a little 90 deg hose that goes from the block to the heater hose block. It was creak and leak. My question is if the hose is replacable or do I have to buy the whole part.
