Re: Closed cooling systems
In my process of looking for an engine, I have talked with several individuals, if any contaminants from raw water, fresh or salt especially salt, closed cooling is only Possible after a complete tear down and proper wash/rebuild and reassembly, I also questioned the need for closed cooling, many people state that closed cooling can cause more problems then it solves, and if properly flushed raw water cooled engines will last just as long, the guy rebuilding my engine told me that unless your trying to protect your $40k Diesel for future rebuilds there is nothing wrong with raw water cooled, he more or less stated gas engines like the 5.0 are throw away motors, they are readily avail rebuilt or new, so why spent upwards of $2k on having a closed cooling system installed to protect a long block that cost less then 3k brand new???
