Ratty2Austin Posted November 2, 2003 Share Posted November 2, 2003 ok, so my power steering pump died on my turbo XT, so I replaced it with another one from a parts XT, and it workes, but it still makes the same sound the old one did before it died (a weird moaning/whining sound) and it is also doing the same thing the last one did- it is foaming the ATF up badly!! will this kill my next pump? what is causing this? if anyone has had this happen or knows whats going on, please tell! thanks!

calebz Posted November 2, 2003 Share Posted November 2, 2003 Possible contamination in the lines?.. maybe someone put some plain old power steering fluid in there at some point? Quote Link to comment Share on other sites More sharing options...
BlueTrain Posted November 2, 2003 Share Posted November 2, 2003 if it isnt bled correctly, it will foam up.. Quote Link to comment Share on other sites More sharing options...
baccaruda Posted November 2, 2003 Share Posted November 2, 2003 maybe you should flush it all with dexron to be safe, and bleed the PS by turning the wheel lock to lock several times, holding it for a second at each lock. don't overfill it either Quote Link to comment Share on other sites More sharing options...

May take a bit for all of the air to be purged out of the system. Keep an eye on the level for a few days after you do the bleed. Quote Link to comment Share on other sites More sharing options...
MaroonDuneDoom Posted November 2, 2003 Share Posted November 2, 2003 are you not supposed to use power steering fluid? i thought that is what it is meant for. Quote Link to comment Share on other sites More sharing options...

From that little snippet, I'm gathering that he's replaced the power steering fluid with ATF... at which point, if he does top off the pump with power steering fluid, it probably would foam...

calebz Posted November 2, 2003 Share Posted November 2, 2003 Originally posted by MaroonDuneDoom are you not supposed to use power steering fluid? i thought that is what it is meant for. Take a look at the cap on your PS unit. It says to use ATF From that little snippet, I'm gathering that he's replaced the power steering fluid with ATF... No.. not replaced.. thats what's supposed to be there Quote Link to comment Share on other sites More sharing options...
rallyruss Posted November 2, 2003 Share Posted November 2, 2003 power steering fluid is virtualy the same stuff as ATF but it suposedly has more antifoaming agents in it. I have used PS fluid with no trouble for many miles. I see vehicles all ther time at work where the fluids have been mixed up with no problems. sometimes it does take a while to get all the air out of a system. if you already attempted bleeding and drove the car for a good while. I would check for leaks. its rare but if you have a leak in the system that alows air to be sucked in at some point you would have a problem with air bubbles. doubt thats it but just a thought.

Mac Posted November 2, 2003 Share Posted November 2, 2003 I've heard that if the P/S pump boils over for whatever reason, the fluid should be totally replaced. Is this true or an old wive's tale? Where are bleeder screws located for the P/S? Quote Link to comment Share on other sites More sharing options...
Dr. RX Posted November 2, 2003 Share Posted November 2, 2003 When you replace the pump and refill the tank, jack the car up off the front wheels, have the engine running and turn the steering wheel from lock to lock several times. This will circulate the fluid, and get all the air out of the system. Quote Link to comment Share on other sites More sharing options...
rallyruss Posted November 2, 2003 Share Posted November 2, 2003 never heard of p/s fluid boiling over. cant be a good thing. there are no bleder screws. you first add fluid. then with wheels off the ground turn wheels lock to lock a few times slowly. check fluid and add if needed. then start car and do the same thing. again top off fluid. if the car still makes noise drive it for a while it will usualy work the air out of the system. ( unless its my wifes car that hates me:banghead: ) this is the procedure I was given way back in school. Quote Link to comment Share on other sites More sharing options...
BlueTrain Posted November 2, 2003 Share Posted November 2, 2003 this is according to haynes manual... 1. chck fluid..add if necessary 2. if vehicle has air suspension..lower it...disconnect battery ground 3. raise and suppoert front of vehicle with jackstands 4. turn sterring wheel from lock to lock 2-3 times and recheck fluid level 5. start engine and let idle. turn steering wheel from lock to lock 2-3 times again and recheck fluid level 6. lower front of vehicle to ground. run engine, and again turn steering wheel lock to lock 2-3 times.. recheck fluid and position wheels in in the straight ahead position... 7. bleeding is complete if fluid did not rise from the full mark..more than .200 in (.5mm) and if no foaming is observed when engine is stopped.. hope that helps...

Ratty2Austin Posted November 3, 2003 Author Share Posted November 3, 2003 well, it worked for a few minutes- but then it started foaming up again... i will try driving it some and see if it goes away Quote Link to comment Share on other sites More sharing options...
the_bard Posted November 3, 2003 Share Posted November 3, 2003 No.. not replaced.. thats what's supposed to be there Guess I'm going to have to look at the PS reservoir cap... learn something new every day Quote Link to comment Share on other sites More sharing options...
PHATBRAT Posted November 3, 2003 Share Posted November 3, 2003 Yep, I'd say it's a pinhole somewhere that is sucking in some air whether it be the cap or a line. Don't know how the line would suck air in if it is pressurized though. Quote Link to comment Share on other sites More sharing options...
