Broken hose

[alpac]

I recently posted a thread about a coolant leak from a small upper hose. Well, yesterday 2 plastic pipes broke on me Coolant all over the engine of course. Fortunately I was about 500yards to my home when that happened. It was too late in the evening to go to BMW and get the parts. Also my extended warranty for some reason does not cover hoses. I looked on line and BMW only sales the entire set of hoses and pipes. When I inspected the damage I found that all hoses were in good condition but the 2 plastic t-shape pipes obviously broke due to fatigue. Honestly I would have expected much better quality material on a BMW. These plastic pipes looks very cheap.
Today I was able to fix the problem by replacing the 2 plastic broken pipes by 2 metal ones. I found one at Pep Boys and the other one at home Depot. I had to work on the big one a little bit with an electric filer so as to be able to fit a small hose on it. After fixing it I drove the car all afternoon and everything is fine. If something else breaks in the cooling system this will certainly not be these 2 metal parts. Bottom price: 25$ for the fix and 2 1/2hours of work.
