How to fill a radiator on 99 Chevy Truck?

I bought a 99 Chevy Truck last year and I need to flush the radiator.

Im used to working on older cars and this truck doesn't have the cap on top of the radiator like what I am used to.

Do I need to take a hose off an fill from there or do I have to go through the resoviour?

    You should fill through the reservoir, but I haven't seen one without a cap of some kind.

    That is where you should do the flushing, or have it done at a shop.
