Well...I did it with compressed air, and a ton came out, but then I removed it and there was still a lot there. It get's wedged between the radiator and ac condenser.
The best way is to pull the radiation. Doesn't take long and if you're careful you won't damage the fins.
These are generally good radiators but they will clog up from debris like any radiator. But they lend themselves well to being recored and if you get a HD recore you have better than new.

 

Yes... he is right. A clogged radiator does not mean that it is 100% clogged. It means that some of the tubes in the rad are clogged and the coolant goes only trough some of them. also, the build up isolates the heat and it is not transmitted to the exterior.

Take a look at the pictures of the radiators in this page:

Fall, 2002 Troubleshooting Professional Magazine: Roadside Overheating Diagnosis

Also, this how a clogged radiator looks:

^What they said. Cooling system components are NOT parts that either work or have failed. These are components that age and their efficiency declines from the moment they are first installed and used until they are either replaced or suffer complete failure.
As the radiator ages it becomes more and more covered with build up and interior ports become smaller. Gradually decreasing efficiency.
Water pump; bearings slowly wear and the fins actually reduce in size over time, reducing efficiency.
Thermostat, same thing...
Pressure cap, ditto...
When these parts are all new, they work great. As they age, not so much. I would start with the lowest cost maintenance you can do and go from there. OR, you could do the entire face lift.
New water pump, have radiator cored, replace t stat, replace pressure cap, new hoses, back flush heater core, and Bob's your uncle.
Let us know how it goes.

 

Your earlier statement regarding the head gasket leak and the coolant makes no sense to me.

It is great to hear that you have gotten 12 years of service and 200k out of it so far, but it does sound like it may be overdue for a few possible routine items.

I would pull the rad and do a total flush at least. How about the routine maint?

 

Congrats on hitting 200K! I hope mine makes it there. I'll be checking back on your progress in hopes it might help me. Good luck.

 

Sorry for the delay...it appears my issue is head gaskets leaking fluid from the back of the engine.
My question to y'all is this:
Being That it is the beginning of July and I am something of a DIY'er, I am going to attemp to do the job myself when the seasons get a little cooler outside. So I plan on taking it easy and driving round trips of 30 minutes or less. Is it possible overheating can occur as long as there is plenty of coolant in the system?(refilling reservoir after each use, and not letting the coolant get more than a half inch or so below the recommended coolant level)
Also, can someone point out somewhere that lays out what parts come off in chronological order in order to give me an idea of organization.
There's just so many parts on top of the heads and I don't not want to waste time taking something off if I don't have to.

Thanks Disco dudes!

 

That would be the RAVE shop manual. Overheating can occur if there is not enough coolant, or if combustion gas enters the cooling system. Here's a pix of what could be going on inside your HG.... first it leaks to outside, then to inside. I'd find a shade tree and get after it. You can plug in a fan.
