30k service questions

[rogeryung]

Hi, I'm planning on doing my own 30k service for my 2002 OBS.

I have a few questions for anyone who could help:

1. Coolant - I was thinking of using already premixed Honda coolant with distilled water from the local Honda dealer. Makes it easier since I don't have to mix water myself. Would there be any problems using the honda coolant in my Subaru? I think the honda coolant is specifically designed for aluminum engines.

2. AT fluid : I've read about people using Mobil 1 ATF. Is this recommended or will any dexron III fluid be ok?

3. Front/Rear differential: Is the front differential the same as the AT? Or is it separate? If so, does it use the same gear oil as the rear, which I think has to be GL 5 rated, or something like that.

Also, I read that the differential plug in the rear needs fluid packing ( Three Bond 1105 equivalent). What is this and is it sold in general auto part stores. Do you just spread on the threads?

What quantity of gear oil do I need for the differentials?


4. PCV Valve - Can anyone tell me where this is located on the 2.5 liter engine?

5. Brake Bleeding: I've read somewhere about speed bleeders. I went to the site, but didn't see my car's year and model listed. Does anyone know what size bleeder I need? Also, are these speed bleeders reliable and do as they advertise?

I would really appreciate any help that any of you can provide.

Thanks

Roger

Here's some answers for ya... but don't quote me on this.

1. why not use Subaru coolant you can buy at the dealer? Or do what I did and just buy pre-mixed ones and make sure it's the green one!!

2. Mobil 1 ATF is great. Synthetic is a little better than dyno oil since you won't have to replace it sooner and it breaks down longer than the dyno oils.

3. You don't have to change the front differential oil since I think it uses the ATF you drop in. But if you plan on dropping the pan to get the used ATF out, make sure not to replace the ATF filter (black color) since you really don't have to. It's expensive, from what I hear.
The rear differential you can change yourself. Go to scoobymods.com and get more info about it and what oil to use.
no idea about the "fluid packing " you speak of. I just unbolted and bolted the plug back in. No leaks at all!

4. PCV valve is just under the left of the airbox (when u r facing it), if I can remember. Scoobymods has your answer.

5. I have the speedbleeders...but honestly, I haven't used them ...yet! pm Oakos Automotive in the vendor pages and he can give you more details.


Also, read the manual to get more info on the fluids to use and check scoobymods for even more info. If that's not enough, do more searches on here. I do have some extra suggestions for ya...
if you haven't replaced the sparkplugs yet... do so! My 01 RS came with Chumpeeons and I replaced them with NGKs and they are great!
also, start using Mobil 1 synthetic oil on your next oil change and your baby will thank you for it.

good luck!

thanks. I am planning on doing the plugs. Figure that is a no brainer.

Do you know what size speed bleeder fits my car?

Thanks for your help
