    Coolant Flush + Replacement

    Hey lads, what's the best way to go about flushing an M52B28TU? The current fluid has heavy corrosion present and want it all flushed out and bled. What would be the easiest way?

    Take the rad hoses off, remove the thermostat and run water through the rad and the block.
