Does the SC 430 require special fluid for the power steering? I generally use any ATF for the job on my other cars.

 

For my power steering fluid I use Valvoline DEX/MERC ATF in both the SC430 and GX470.

 

On your recommendation, thats what I got at Rilleys

 

I used what I had for the tranny - Toyota T IV or equivalent - just refreshed the fluid in the reservoir via multiple extraction refills over a several week period through the summer. Though mine is a 2005 so 2006 onwards may have different requirements for the fluid.

 

Plus 1,the Toyota Red Fluid works for the Power Steering too.

 

I was having a bhzzzz from the engine compartment....sounde like air bubbles in he power steering. Added 3-4 oz of Valvoline and the buzz went away. First tim in 100k that it has needed any.

 

Have a friend who lives in my complex with and SC430 and they use Mobil 1 ATF. Same as I used to use on my RX300. My CT does not require any fluid for power steering.

 

I used idemitsu pst fluid. Its the oem fluid according to the car care nut.

Same here. This is what I have in the tranny and PS reservoir. https://www.idemitsulubricants.com/product/atf-type-tls

It's Toyota T IV equivalent

 

Don't know if he said that but if so he's wrong, read the TDS that fluid is for Honda.

 

Toyota Trans fluid works as recommended by Toyota. I have been using it for years.
