Featured Replies

Hey Fellas; I have a 93 S-10, with a standard shift.It is a hydraulic clutch system. The reservoir

is a bit low. It says to top it off with SAE 30 fluid, Is thsi the regular SAE 30 Brake Fluid, or is there a special clutch fluid to use. I looked at a can of SAE 30 Brake Fluid and it says to use for cluths also. I know very little in this department.

Thanks

i always thought it was good ol dot-3. id see if you can get a bit of the old fuild on a rag and smell it. should be easy to tell brake fluid from something else.

Muddy, as a former tech, I'll recommend always check the owners manual, if you can. DOT 3 is typically used as the fluid for most (not all) hydraulic clutch systems. Top it off, but by the way, it is a good idea to have it flushed & refilled, just like a brake system. Brake fluid is hygroscopic (absorbs water), so take note.

Thank you much. It was right there I can use the brake fluid. I would get it flushed . but I am selling it this spring

I surprised you didn't top it off with root beer. ;D

Regular dot-3 brake fluid will work. I don't know if they make a 'clutch fluid' or not, but I've always used the brake fluid. Just top it off, and you'll be good to go.
