Hi guys, For simplicity's sake I'll give everything in bullet points. Car: - 2001 Mitsubishi Mirage coupe - 6A12 MIVEC engine from an FTO - OEM FTO PS cooler is fitted BUT it is obstructed by the front bar and has no airflow basically Symptoms/Problem: - Power steering fluid sprayed everywhere from reservoir - PS pump sounded like a supercharger (quite loud) - Black dust like debris around where PS pump is - Brand new Gates PS belt snapped Conditions during issue - Car was on a race track and was revved to 8,000rpm repeatedly - Belt snapped 45 mins in (end of 3rd 15 minute session) - Fluid was new dextron III - Pump had been making supercharger noise for a long time - The pump spins freely by hand after the belt snapped My thoughts: - Could a faulty PS pump have caused belt slippage and hence belt snap? Would this be the black belt dust near the PS pump? - Was the PS fluid sprayed everywhere from the reservoir due to overheating and could this have caused the belt snap? - One of the lines to/from the PS pump has been leaking fluid. Could this have contributed in any way? And finally are power steering pumps rebuildable? Any advice is greatly appreciated!
