how to flush. is this a verb question or a product? noun?
how to , or asking where to buy flush kit and flushing compounds.
the only new compounds are jug of orange oil, (safe for the environment all the other ones are off the market )
take it to a shop with flash the system.
end short story.
LONG:
DIY, good luck chuck.
the coolant is toxic as heck, kills people pets, etc.
and must be kept out of sewers and storm drains, for sure.
unless eating toxic fish is ok>?
It can be done, kinda clean,
but is super hard at home.
drain rad, drain block , drain both and catch it all and take it the county reclaim, (for toxics) use a large catch pan, to do that.
now flush it with water hose.
the book says back flush all hoses. and the RAD.
pull all major hoses. this is what is done, for 100 years now.
up to NOW (near)
black flush block and heater core and RAD.
now lets ask why do this at all? if not UGLY.
first off if you keep the system serviced, it will never need a flush.
it will not go to like this.,

not only that, in the USA we took out the sulfur in fuel.
doing that prevents the coolant from ACID attack.
so the coolant never goes ACID now, like 20 years ago.
so no more 2 year, service, due to that FACT.
it's a 5 year service and cap off shows coolant looks great.
on old cars, anything is possible
and flushes must be done, to cure the UGLY ONEs.
seen in the photo above.
end old post answer.
