I had to fill mine shortly after I bought it. The factory didn't connect a coolant hose and I lost a lot of antifreeze. Problem is I don't remember all the steps and don't have the book with me tonight. I do know you fill the tank, get it up to operating temp, remove the cap under the bed to bleed air, add as necessary. I don't remember if you remove the cap when it is hot or wait until it cools. It does take a while because you have to let it cool completely before trying it again. Mine belched out a lot of antifreeze all over the engine. I'll check back tomorrow evening to see if someone has gotten you the exact procedure. If not I'll check the book and let you know what it says. I do know it doesn't say anything about elevating the front of the machine.
