Filling engine block with coolant
If I were to completely drain my engine and radiator of coolant, would it be necessary to fill the block up through the thermostat housing and the radiator, or could I just fill the radiator and let the coolant pump into the block while continuously filling the radiator and letting air out?

if its completely dry i would be worried alittle running the engine for the time it takes the stat to open up with no coolant in the engine. but i would guess its completely fine since thats what happens when u install a new engine, right....

actually... the reason I posted this was because I witnessed a new engine install in a corvette after the owner punched a hole in one of the pistons, anyways, the filled the block with coolant through the thermostat and the radiator. I'm not sure whether this was necessary or not or whether you only need to do it for a new engine. I dont' need to take off my housing, i just want to flush the coolant, but i might as well throw in a new thermostat while i'm at it. Anyone else have any thoughts?
Thanks.
Thanks.

if you fill the radiator it will fill the engine block....the radiator is higher than the engine ....gravity does the rest.
I know cuz I was filling the radiator up with an empty engine block and i have the thermostat housing off and it started flowing out of the block like crazy.

He's exactly right. I just put in a new 383 and filled the radiator up, and before starting it for the FIRST time, I changed my plans for the cooling fan system and I took out the fan switch and lost a good amount of coolant out of the side of the head. So no, don't worry about the block being dry. But still keep an eye on the level when you start it back up.
