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!
