Prestone Super Radiator Cleaner - 5.99,you need 2 bottles start to finish.
Prestone Radiator Flush Kit - 3.99
Radiator Cap - $5

Total Cost: $20 or so.

Might want to buy:
New Hoses all around, no use cleaning out old hoses, and if you do get the radiator clean the build up on these could clog it back up at a later. You don't HAVE to do this, I didn't. Cost is about $50. You need upper/lower Radiator hoses and 2 heater hoses.So total cost with new hoses: $70, not quite as cheap as not doing the hoses, but if you get a new radiator you would want to get new hoses too anyway, for the same reasons. So up to you and what you would like to do.

Now let's get too it,

First your going to want to drain the Radiator, the drain plug is on the passenger side of the radiator, in the bottom corner, it just twist out, I alsosuggest removing the plug once you have it unscrewed, just pull it straight out to remove. If you have small arms you can get to it from the top using the space between the battery and the fan shroud. If not, you can get it from the bottom too. Just don't later loose it in the engine like I did. Had to buy a new one. Still haven't found the old one. Drain it out into your bucket and dispose ofthe Antifreeze accordingly. On mine when it was clogged even with the plug removed it just kinda dribbled out...but now it SHOOTS out if the plug is removed, hits the axle. Or in our case the TTB So if it's not badly clogged DON'T remove the plug, antifreeze will go everywhere. If you using water while your working on it like I am it doesn't matter so remove it, drains faster.

Next your going towant to put the Prestone Back flush kit in. First your going to want to find the heater hose that comes from the TOP of the water pump. (according to Prestone's directions at least, I don't know if it matters) Your going to want to find a good place to cut the hose and place the T for the flush connection. This is going to be where you attach the garden hose for the back flush. So it needs to besomewhere easy to get to. I have mine in the heater hose about 8" back from where it goes into the heater core (see pic below). Cut that hose (with hack saw or something sharp, these are tough hoses so if using something sharp be careful) To save time remember to put the hose clamps on BEFORE you put the T in.... Not that I did that or anything. I do have a T on both hoses, but that was becausesomeone had cut both hoses before I owned the truck and they had used connectors to reconnect them that were too small. The kit was cheaper then a new connector so I have two flush T's now!

Also remove the hose from the overflow reservoir to the radiator at this point. It's the small hose that runs from right under the radiator cap to the plastic reservoir that holds the extra coolant just to thedrivers side of the radiator. I detach it at the reservoir, your going to want to clean that out too. Catch the Antifreeze if you can, It'll kill the grass! I then just leave it unhooked until I'm done and it's time to refill it. If you don't do that at some point your going to overflow the reservoir and get Antifreeze all over. Once it's drained you'll want to clean it out well. You can justkeep filling it up and letting it drain out. You'll see, keep that up until it runs clean.

Now your going to flush the radiator, first hook up the hose to the flush T, remove radiator cap, put in yellow neck thingie to shoot water away from your belts, and make sure you haven't reinserted the drain plug, we want it out for now. And hit it with the water.... let it run until the water coming from...
