By removing the engine block heater how much coolant will still remain in the engine?

What is the best way to remove the engine block heater?

Usually for the lugs I used a chisel punshed a hole adn pryed it off, since the heater has something you can grab I would try to pry it off first.
If it breaks off then I would use a chisel.

I'd say you're still gonna have a few qts left in the bottom of the water jackets. The last block heater I replaced had a bolt in the middle which i loosened until I was able to easily pull out the heater. It had the expanding rubber plug on the inside, plus the element.

Ok so I have the OEM 1978 engine block heater removed. I'm comparing it to the newer model. My old one is made out of solid brass. The new part is stamped.

I would rather go with the old one being that it is solid brass.

The nut on it is staked. I'm going to have to find a new brass screw and stake the nut. This is a nice feature as it prevents the nut from getting into the block.

Any one else removed the oem heater and found it to be solid brass.
