You may have to acid clean it. Or try boiling it out my help. Acid will do the job but be careful.

I have sprayed several cans of carob cleaner through it, blasted it out with an air hose, put it in the cleaning tank with a biodegradable solvent running through it for hours, ran water hot and cold through it and still getting specks of scale out of it. When I thought it was clean I filled it with clean oil and let it set overnight and when I poured the oil out there was still a lot of scale coming out. Any suggestions on how to clean it. I would like to stay with a stock oil Cooler if possible. Jack Cooper kr2coo...@earthlink.net Fayetteville.
