Catastrophic Coolant Hose Coupling Failure Registry

Rennlisters, during my race at Miller Motorsport Park I had a coolant line failure that should not have occured. My 2004 GT3 has a secondary coolant line from the waterpump next to the primary coolant line. This secondary line has a press fitting into the waterpump with no fastner. It then travels up to the powersteering pump where it is connected. Both pumps have the pressed fitting with metal pipe, both pipes are joined with a rubber hose using hose clamps, I would image for vibration. It appears to have been bonded with adhesive, and after 7500 miles it failed, just popped out during a race which cost me my National Championship and possibly a engine. No warning, no drips or leaks, just pop and a spray of coolant on to the engine and right rear suspension.
Would like to hear if others have had the same problem, because trust me, I will give Porsche and ear full...
Look and weep...

^ add me as a victim of the above fail too!

Repaired with OEM parts.

I'm surprised there has not been a class action lawsuit undertaken. Porsche is well aware of this problem (Excellence Magazine) and has done nothing to rectify the problem. costs for repair excedd $3500.

If you could pick one turn at the Glen for this to happen it would be 8. I'd consider myself lucky. Must've made for some interesting powerslides for those following...

Again, fortunately, there were no casualties behind me.

If/when someone dies, even VW won't have the liability insurance to write the check to compensate the families of a couple of wealthy GT3 RS owners in pine boxes.

Other than changing all the Hoses - anything else that can be done to the couplings to prevent the failure? TB weld? Sorry for the dumb question but just trying to be proactive!.

Ritesh it is not a hose issue but a press fitting issue. Do a search here we have more information than Porsche would like us to.. : )
And yes welding them is a final solution.

And get your check book out, the engine has to be removed and porsche charges $3500 just to drop it! I had the fittings replaced by porsche only to have the failure occur a second time at the track. Their liability is growing!
