My truck is leaking antifreeze from the top of the motor looks like by the back side of the intake how can I make sure that it's leaking there because there ain't no oil and water mixture in the oil or no oil in the water

Hello, it's an external leak, yes? If so, you can have the cooling system pressure tested to help determine where the source of the leak is, without having to inspire actual overheating while driving the vehicle. I suspect some kind of hose leak, but can't tell without hands on testing happening. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
