Brand new serpentine belt. I aligned the PS pulley surface with a straight edge to match to the other pulleys. It ran fine for about three days with no issues. I could turn full right to left with no hesitation spots.
It failed when I was backing out and making a left turn, It failed instantly. I could here the pump making clunking noises.
I did have to transfer an electronic flow regulator from the old pump to the new that was on the high pressure line.
I was trying to think of what could cause the second failure before I install and third pump.
Bad new pump, Contaminated fluid? ( How can I do a full flush? and maybe add an in line filter to the return. Bad Flow regulator ( not even sure what that does that would cause trouble). Bad steering box, the only other part I can think off is the steering sensor on the column but not sure what that would cause if that went out.
It is an AUTOZONE ATSCO remanufactured pump. I did a little research on the Internet and had a few people talking about the same problem but there was no replies that resolved it that was posted. Someone had stated that if the flow in the pump gets restricted that pressure could build up rapidly and that could cause the pump to seize, but I just listing everything I have seen, not sure if any of these are valid.
I DID NOT flush the system though before replacing the pump. Is it possible that when the old pump siezed it could have introduced contaminant into the fluid that made its way into the new pump?
Yes, if you could send me the bleed instructions that would be great, In the flushing procedure how can I clear the fluid that is in the steering gear box?
ya for sure. Here you are. Good luck.
Power Steering System Flushing
Important: Do not reuse any drained power steering fluid regardless of appearance or condition.
Important: This step may require 4 L (4 qt) of power steering fluid until the draining fluid appears clear.
Important: Do NOT run the engine without the power steering fluid at a minimum system level.
Power Steering System Bleeding
Important: Power steering fluid level must be maintained throughout bleed procedure.
Important: With hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF. This will discharge the hydro-boost accumulator.
Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.
Will try it this weekend and see what happens, I have the new pump just need to get more PS fluid for the flushing and bleeding.
Yes , Thanks for your help.
Sorry first time user here and forgot to hit Accept, just hit reply. One quick follow up. What do you think of an In-Line filter on the return side? Overkill and not needed? Good idea, couldn't hurt. May cause trouble ( maybe if it get's clogged).
