I'm planning to bleed out the clutch line and replace the fluid.. and I noticed on the forum here that some people will replace it with DOT 4 fluid, but in the service manual it recommends an equivalent DOT 3 .... so which one should I use?... what's the difference between these fluids? (other than the temperature rating) Any info/ insight would be great. thanks!

 

Only difference is formulation. A lot of people feel DOT3 and DOT4 are the same and can be mixed, readily switched between,etc. Others feel that once you use DOT 3, you stick with it, i.e. you should replace with what the system already has in it.

for a street car, the minor differences are negligible so you might as well stick with a good DOT 3. Just get a reputable name brand and you should be good to go.

 

Thanks for the reply, Dave... DOT 3 it is.

 

Lock this Dave. perfect advice.

 

Hi Dave, ... one other question: would this also be a suitable replacement??? --- Gunk's Clutch Fluid, for manual shift vehicles (please see pic)
