Reply to "Flushing the Coolant System"

To really drain it, I think it’s best to disconnect one joint on each side in the plumbing underneath.

That way you get a big rush of fluid, hopefully carrying as much gunk as possible out.

My radiator has a petcock on the lower side of the radiator (driver’s side), but I think you’ll only get a trickle out of something like that.

Can you run “radiator flush” for a week or two before you are ready to do the deed? Let it run and circulate, make sure the thermostat opens, and pump it through the engine & cooling system. That stuff is really just a mild citric acid solution.

If you are bringing the car back to life, you’ll want to change all the hoses and tubing as one of your first projects….
