DOT-3 Vs. DOT-4

You can mix them, but its better to flush out the DOT3 and have only DOT 4 in the system. DOT 4 has a higher boiling temperature then DOT 3.

MOPAR provides us (dealers) with DOT 4 Brake & Clutch Fluid P/N 454625AC. It specifies on the bottle "Can be used in place of DOT 3 fluid". DOT 4 is an OEM fluid.

4549625AC is the part number for the MOPAR DOT 4 fluid for those that are interested. I just noticed I forgot a digit.
