...as for disposing of the coolant...
A neighbor (local fire fighter) did a coolant flus on his EB and didn't know what to do with the coolant. He did some research and made some calls, and came up with the BEST (?) option to dispose of it is to pour it down the drain while the faucet is running. He said the water treatment plan has the means of taking it out of the sewer????
...thoughts? Can anyone confirm?
