When I last left you I was on my way to my son's shop for a engine/tranny/diff/power steering/cooling fluid change out. First it is always nice to have the right equipment and tools...and in this case expertise (yes he is my son but he is good at his trade :thumbsup: ) First the diff... pump out old stuff and fill with Mobile 1 75-90 and rotate wheels to get diff gears etc washing thru new stuff...pump out and repeat...pump out then do final Mobil 1 75-90 with GM posi friction fluid. Tranny...drain and fill with the BMW spec Castrol TWS. Engine oil..drain and fill with Amsoil AMO..oh here is a little tip he does for the top loading oil filters so as to minimize spill etc..punch a hole in the filter top thus allowing remaining oil to drain

Of course while working under car always time for the cell call from his lady

Now to results.. a very NOTICEABLE reduction in tranny noise and rear noise...much nicer sound and while we were under the Z found out source of a minor but irratating heat shield rattle..left side CAT shield and we corrected...
Now a few last items and I be ready...
This is fun

When I purchased it had 1340 and now has about 1500 (I have only owned for couple weeks and most of the time has been spent detailing and upgrading)..just waiting for fair weather and it WILL be driven :thumbsup:

God that car is so clean, that's awesome!=D>

It must be nice to have a tech you can trust to do it right! I'm envious:mrgreen:

Just a Q, if you wouldn't mind? How did you change the p/s fluid? I've been using ther turkey baster method at the resevior....not exactly a very good way to change the fluid....not very effective & doesn't make me feel like I'm doing anything useful.
Thanks
:cheers:

How did you change the p/s fluid

When all else fails use the turkey baster....lordy how many of us use that special garage tool..it works in many cases and is part of my tool kit :thumbsup:

But your right in the case of the PS unit... there is a special vacuum pump/sender pump unit made by BG (called a Power Steering Service Center)

http://www.bgprod.com/products/steering.html

First it sucks out the PS resevoir then you add the can of BG Quick Cleaner and turn on engine and work steering wheel...left right left right etc etc ect....cleans out the entire system including the PS rack... then the machine sucks out fluid and replaces with BG Power Clean fluid...It is a really nifty set up.

Are you saying it just sucks it out of the reservour? Or it hooks into one of the lines somewhere? The way you describe it, it sounds like cleaner could be left behind.

[ZR1Vette]

The cleaner is removed via the resevoir but about a gallon of the new PS fluid is pumped in and removed thus displacing the cleaner (all this is done while engine is running and PS unit is pumping so rack, lines and resevoir/pump are all cleaned and new PS fluid installed)

Hey Mike thanks for the response!:thumbsup:

I'll have to look up BG and see who around my neck o the woods does that treatment.....till then I'll keep at it with the turkey baster....it's just so slow & tedious. Seems like I never get caught up with that job!

i know the feeling ,but it keeps me busy on cold nights:mrgreen:

Hey Michael, not to nitpick or belabor it... But that's like if you had a container with salt water in it. If you could only remove it by pumping half of it out, and re-filling with fresh water, how many times would you have to do that until there was no salt in the water?

Personally I hate flush products for that reason. It can be extremely hard to ensure they are completely removed, and often times they are corrosive to the systems they are used in. Just my opinion though. And the risk may depend on the system. Coolant flush left in the coolant might be no big deal as it just rushes through big passages and such, what can it really hurt? ATF flush fluid left in your automatic might be a big deal as there is a lot of sensitive stuff it can corrode.

Anyway, like I said, just an opinion. Personally I'd play it safe and just flush with fresh power steering fluid as you have been doing Tom.
