How to Flush the Oil Cooler?
I'm still working on swapping the engine in the 300D . . . the service manual suggests flushing the oil cooler and lines and anything else that may have been exposed to the oil in the seized engine . . . for fear of metal shavings I assume. What should I use to do this? Not water, right? Maybe some horribley caustic chemical?
Thanks,
Eric
