Hydraulic Clutch Fluid
Noticed my clutch master reservoir is down a little, figured I would top it off.
I just got back from a couple auto supplys, a NAPA and a GM dealer. Auto supplys don't know what I should use, GM dealer says GM fluid (12345347) is discontinued. Any idea what should be used to top off? Also any way to test the fluid in the system before I potentially contaminate it?? Not sure what previous owner might have used??? Any advice is appreciated. Thanks, John

Re: Hydraulic Clutch Fluid
I flush my clutch master cyl every year and refill with DOT 3. Appears to work just fine.

Re: Hydraulic Clutch Fluid
Looks like summit has it, according to other sites its DOT3 with an addative; I have run DOT 3 with no issues
I think Summit has this in stock
