I'm in the process of converting my engine away from DexCool and the sludge and such was very bad. The Westerbeke distributor even admitted to a problem with water pumps, clogged cooling passages and other items they suspect to be caused by DexCool due to the numerous disimilar metals..
I currently have my HX off and I know most engine flush products require you to run the engine to warm it up before use, except for Rydlyme. This is to open the t-stat so circulation of the acid can work but wonder if Rydlyme can also work when cool? I like Rydlyme and will continue to use it unless someone knows of a better product.
Seeing as I am on the hard & indoors with no running water I plan to do this with an external pump, & the t-stat removed by tapping into the HX supply & return lines.
The question is, for the chem engineers amongst us, other than Rydlyme (not easily availble locally), what would you use as an alternatove to circulate through the engine. Keep in mind this is not running or warm, in an attempt to clean out the sludge left by the DexCool? I trust Rydlyme but was curious of there is something new I may have missed. A magic bullet if you will....
I know there are folks here who have a good handle on all things chemical and figured you guys might know better than anyone what other productst may work on an engine at roughly room temp (boat is in the barn for a bottom job and barn is roughly 68-70f).
With an external pump, the engine off and t-stat removed what else can I circulate through the engine to clean it that will work at room temp other then Rydlyme?
