Does anyone know what acid the radiator shops use to flush the scale and crap out of their radiators. Could it be muriatic acid??? Has anyone ever done this themselves and if so, how did they do it and what concentration did they use?

Check a parts store for a recommended name brand flush. Follow thw directions on the can/bottle. Then flush out the radiator in reverse (use a rag on the end of a water hose and stick it into the bottom opening in the radiator. Have the top hose off, then run the water to "back-flush the radiator. I would pull off the thermostat housing and do thw same thing to the engine.
Be sure to use a new thermostat, gasket, upper and lower hoses, and cap. I am having great success running a 60/40 mix of antifreeze. (60 is antifreeze).
