Draining Coolant

[tucker0104]

Is there a correct way to drain coolant out of a 7.3L? I am getting ready to replace gaskets and seals on my oil cooler and am going to change the coolant. Is there a correct way to get all of the coolant out?

Draining it won't get it all out. Gotta flush it. Here's a commonly-followed procedure: Coolant changing instructions... - Diesel Forum - TheDieselStop.com - a bit of overkill; you may choose not to refill with distilled quite so many times. But you get the idea. Flushing kit is like $3 at Advance Auto.

There is a plug in the block right above the oil filter that you can take out to drain the coolant in the block. Makes it much less messy when you take the oil cooler off.
