Rapid coolant loss

Engine & cooling all 24 →
No incident occurred. However, based on my knowledge of the failure of the coolant fittings in my car and wanting to take a proactive stance I elected to move forward with a remedy. While at the dealership on another matter, the engine had been removed allowing limited access to a number of the coolant fittings. Since the dealer disavowed any knowledge of the problem and was therefore unwilling to help I took it upon myself to mechanically fasten those coolant fittings which I had access to. Mind you all while the dealer looked on. I provided all the tools , parts and pieces which I needed to drill and fasten those I had access to. Others , I simply safety wired the hose clamps hoping it would prevent a failure in the future. Many failures have occurred at high speed track events resulting in catastrophic vehicular loses. …
"permanent" coolant hose attachment failed; it came loose from its mounting in the engine resulting in coolant sprayed onto tire, with complete loss of control during a turn , including 270 degree spin, and leaving roadway; fortunately no other vehicles were nearby, so a collision was avoided. Apparently, this is not an unusual failure with the GT3 engine. Note: this was not a coolant hose or hose clamp failure, this was a structural failure of a permanent engine component to which the coolant hose mounts. Given the serious safety issues at stake, both to the driver of the vehicle and those also using the roadway near the affected vehicle, it should, in my opinion, be addressed with a safety recall as soon as possible. This is a design defect that is undetectable until the part fails, with potential loss of life and substantial property damage.
