The Stovebolt Site Forums The Shop Area Engine Shop Best way to flush an engine block.

Hey all, I bit the bullet and ordered a new radiator for Gertrude (61 C10 w/ 235 and a 4 spd). I am going to replace the thermostat and rubber hoses while I am doing this as well.

What is the best and safest way to flush the block? I don't want to harm anything or, worst of all, leave deposits behind that will damage my new radiator.

Also, should I change my water pump since I am digging in this deep?

The only issue that made this necessary was the leaking factory radiator, so no other issues were presenting in the cooling system.

Thank you,

Kyle
