Re: Manifold/Block drain instructions for this dummy
To be quite honest, those hoses need to be removed and thrown in the trash. Then get a couple of brass pipe plugs to put into the holes in the block and manifold.
The holes in the block and manifold tend to fill up with sand, mud, rust, etc and plug up the hoses. Then just a little bit comes out of the hoses, but water is still in the block and manifold, then when it freezes, you get to go looking for a new block and manifold.
With the plugs, just remove the plug and use a wire to clean the holes out so the water drains, and put them back in. Job done, and no worry.
