How do you gents with aluminum blocks, with no petcocks, remove water from it for the winter?? I would drain the water from the radiator re-fill with antifreeze, run the block to temp and store for the winter, flush it in the spring.

Drill and tap a hole in the side of the block, and install a petcock.
My aluminum INDY block is half filled with Rock Block, and a hole was drilled at the top of the fill.
But as RATTRAP has said, just drain the radiator, and fill with antifreeze, and run the water pump to circulate.

You can also blow compressed air in the upper hose and it will blow it out the lower. It would remove enough to not worry about freezing but won't get all of it.

I agree. With the water pump running, it will mix the new antifreeze and the left over water in the block. So don't use that premixed antifreeze.

I just winterized mine for the winter even though I have a heated garage. I do it every winter just in case my furnace were to break. I just drain most of the water and top off with antifreeze and fire it up until warm and circulating. Then drain it all in the spring again.

Mine gets antifreeze no matter what....Being in the radiator business for 35 years, I have seen what a little water in the right spot can do if it freezes.
