Default A few basic service questions...

Hi all,

About to do a full service on 96 LS400 at 150K. A few questions:

1. ATF: Type T-II or equivalent. Any good equivalents out there or do I have to go to Toyota dealership?

2. Brake fluid: Shop manual says FMVSS No. 116 DOT 3 or SAE-J1703. Is this regular DOT 3 fluid (gunk)?

3. Power steering fluid: Dexron-IIE ATF, can I use Dexron III?

4. Tranny filter - do I need to go to Lexus or is this a cheap toyota part?

5. Spark plugs - any gotchas?

6. Do I need to change the air con fluid and/or filter?

Thanks for any tips! My LS is still working 100% perfectly and floats on air. Unbelievable, and I want to keep it that way!

Ok thanks for the reply!

T-II ATF $385 / qt at Toyota, $9.45 at Lexus dealership! Go figure

Also the tranny filter is a wire mesh that can be cleaned and does not need to be replaced.

Just one more question - what's the life expectancy of the plug wires. The guy at the lexus shop said if its working fine (which it is) then don't replace them.

Get the T-IV fluid, not T-II, if such still exists. At 150K, most likely the plugs were replaced at 90K, so it might be time to change them anyhow.

are you talking about the pick up screen?

after a couple years it might be a good idea to change them. but if u want to save ur self some money u dont have to replace them till they start giving u trouble
