You don't need to do a vacuum refill, you can do it without any special tools really. However, I'd recommend the funnel that attaches to the radiator filler neck, it will help keep from spilling coolant. Basically park on a sloped surface, with the the front of the truck higher up on the slope. If you don't have slope, use stands or ramps to lift the front of the truck. Top off both the radiator and overflow, start the truck to get it up to operating temps, run the heater on full blast when it reaches full operating temp, and finally, once the t-stat opens, slowly squeeze the bottom radiator hose to help burp coolant through the system. Be careful when squeezing the bottom hose because you can come close to the fan if you're not paying attention. Really, you don't even necessarily need to squeeze the bottom hose, the system will burp itself, but squeezing the hose helps to expedite the process.
