Comparison of Dot 3,4,5 and DOT5.1 brake fluids
DodgeM37 replied to desoto1939's topic in P15-D24 Forum
Dot 3, 4, and 5.1 are all glycol-ether based fluids. The difference is the boiling points - higher number, higher boiling point. The down side to these is they are hydroscopic; they absorb moisture. Which can cause rust and corrosion. Dot 5 is a silicon based fluid is is not hydroscopic. The Military uses this fluid since vehicles can sit unused for long periods of time. However Dot 5 can absorb air if not stored properly and can cause a weak petal. The two fluids are not compatible and when changing from one to the other the system must be thoroughly cleaned or bad things can happen. -
Have several long block cranks out of the engines. Any tips or tricks to see if they are 237, 251 or 265?
