Pentosin CHF 11S in GM Power Steering

[redhat]

Would there be any harm in using Pentosin CHF 11S in the power steering system of 2000-2006 GMT800 trucks, Tahoe, Silverado, Suburban, etc?

These specify GM power steering fluid in the manual.

Try the Honda Power Steering Fluid.

Perhaps, Approvals

As I understand it hydraulic fluids like CHF11s can be used in place of ATF but ATF can't be used in systems which specific hydraulic fluid.

it didn't show up as compatible on the lookup guide for those models

I wouldn't use it. I once had a VW that used that fluid, and when I first bought the car, I went about topping up all the fluids. Not knowing any better, I used universal power steering fluid (that had a GM rating among others) to bring the PS reservoir up to max.

Within a few miles the PS pump was making a ton of noise, fluid turned into brown/greyish milkshake color mess and caused some major power steering issues; effectively ruined the rack. Even after a flush with the proper CHS11S fluid, I still had random stiffness/locking that would occur when steering at slow speeds.

I learned the hard way that these fluids do not play well together. YMMV.

Gm has a TSB for using Pentosin CHF202 in cold weather. I think the tsb was for 08 and up. Does yours have rack and pinion?

Might check rock auto and compare AC Delvo P/N's for the pump and rack. If they are the same, I would think you would be OK. CHF is Central Hydraulic Fluid (I believe). The ones rated for power steering commonly Pentosin. I think LiquiMoly has a CHF line of P/S fluid as well as others.

Pretty sure they connot be mixed with other P/S fluids or ATF. (See 92saturnsl2's post above)

Really good Viscosity Index.
Not sure the difference between. CHF11S and the CHF202, but I think the 202 is becoming more commonplace.

You'll be perfectly fine; I've used nothing but Pentosin CHF-11S across the board after a complete flush and refill. I switched my '02 Avalanche to back when I had it, and the gentleman I sold it to is still using it with zero issues.

The Chf11s is fine to replace the stock molasses syrup mess in USA vehicles.. The cars designed with the hydraulic mineral oil such as chf11s (VW group G002000 & superceded to G004000M2), do not accept the domestic USA products.
