I recently replaced my manfold on my Mercruiser 165 IL6 and backflushed the H/E.<br /><br />I was checking the thermo today and noticed that there appeared to be a jelly like residue in the housing........can I use radiator flush in this case? I was going to fill with water and some kind or radiator flush, run it w/o the thermostat and then flush it out.<br /><br />How does this sound?
