I performed a 2.7/3.2L swap. Both the doner 3.2L and my car are both 1998.
I have a 1998 Intrepid (LH) Service Manual (Chrysler), which states to NOT use automatic transmission fluid in the power steering system. Only use Mopar power steering fluid, or equiv.
Just FYI: this was at the time that ATF+3 was available.
I purchased the pdf manual from the gentleman (forgot his name) whom performs several of these engine swaps and his manual says to use ATF+4 in the power steering resevoir as it states in another pdf manual I have for 2002 LH models.
What changed with the pump from 1998 to 2002 that disqualifies ATF in 1998 and allows ATF in 2002, besides the new ATF+4 being available?
I am being cautious since the engine swap guy has done several of these but doesn't discriminate the use of ATF for any model from 1998 to I believe 2004.
Any clear explanation of what I should use and why is greatly appreicated. Great forum, guys (and gals)!
from what i understand,, ATF4 donsent eat up the "O" rings like regular PS fluid did, , also,, atf 4 seems to make the steering a tad more quiet,, I have a 02 and did a ps flush, used reg ps fluid and i got a kinda a moan noise,, flushed it again with atf4,, all has been quiet for 2 years now.
I discussed this option with the dealer mechanic years ago and it's VERY IMPORTANT to flush the PS system completely if you change from PS fluid to ATF+4. The two fluids do not mix well.
I would like to do a flush. The engine is replaced and system empty besides maybe some in the lines and the rack/pinion. Can I remove the resevoir return line to a container and have ATF+4 on standby to fill the resevoir to fill... then fire up the engine and call it good after the fluid looks nice and red... or do I need to flush a quart, close the system, cycle the streering wheel back n forth and then pull the return off the resevoir again and repeat the fill and flush into my container? I just want to do this properly without any doubt of leaving contaminants or mixed fluids in the system. Thank you!!
I had mine done at the dealer just recently but wasn't there when they flushed the system, so I don't know how much is involved. I'll let someone who's actually done it themselves - and, hopefully, someone who did it a few years ago - answer the question.
I'm following this thread too, I'm also planning a flush. I thought I would syphon out the resouvoir, let it run a bit and then drain the resouvoir again to hopefully get all the old stuff out. Does that that make sense? How much fluid does it take?
