My car started to overheat a little while ago. I inspected the engine afterwards and found all of my coolant was gone:wtf2:! So I looked and finally found the problem. It was a coolant hose that went from my fire wall to the top of my engine, behind the throttle body. Where the hose connects to the engine it was all corroded. When I moved the hose around a little the hose just came off and all of the corroded material just fell apart. My question is: Is their a part that goes between the big metal nut at the end of the hose and the engine or was it just built up corrosion? If their is a piece their, how can i get it because i cant find anything similar to that part online. I would appreciate any info.
