Basically, you want to remove the lowest hose near the engine and drain the coolant out. It's messy. I actually use a pump that attaches to an electric drill and stick a thin hose down from the highest coolant hose on the engine and suck out as much as i can before I disconnect one of the lower hoses. You may want to elevate the rear of the sled after you drain the engine to get any rear cooler fluid out. Then elevate the front 1-2 ft or more and fill the system with 60%coolant/40% distilled water. Start it up and burp it, add coolant as necessary. Drop sled to level, start it, rev it up (on a stand), check and fill reservoir as necessary. Raise front end and start it again, burp it, fill it, drop it, repeat as necessary. If you have a coolant bleed screw it will help you to get air out.
