Cleaning scale out of cooling system (not overheating)
I decided to replace all the hoses on my Westerbeke 30b three engine this week (also painted the engine) as preventative maintenance. I drained the coolant that I changed last fall... about 20 engine hours ago. When I pulled the hoses, I was surprised at the amount of scale and buildup in my coolant system. The heat exchanger looks fine, but the rest of the inlets for items like the thermostat and exhaust manifold had some scale in them.
Now the system doesn't run hot at all, but I would like to clean this out anyway. I'm not planing on pulling the manifold any time soon, so soaking it like a heat exchanger doesn't work. What can I use to flush this system and remove the crud? Any brand of radiator cleaner recommended?
By the way, it's ridiculous how much Westerbeke charges for hoses!
