i searched but i didnt find the answers i needed. when it is an open deck, coolant runs throught hte space right? but what happens when it is a closed deck. where does coolant run through? also, where does the water pump pump water to? where does it get water from? if i could get pictures, that would be a great help to explain this to me. TIA

 

anyone?

 

A closed deck has holes that run the length of the sleeves allowing coolant to pass through them and cool the cylinders. I prefer to retain the open deck because the closed deck generally doesn't allow quite as large a bore due to it's design and restricts the flow of coolant somewhat. I found some pics of a GE sleeved B18a here:

Didn't see any pix of a Darton closed deck block readily available though I've seen them on here previously.

 

and what about the water pump question?

 

cmon, someone has to know

 

Most people probably don't understand the question, I'm not sure I do either. The water pumps water through the water channel on the back of the motor(B series) it travels through the heater, water jackets, & radiator.
