Dish washer liquid soap works really good...its cheap and simple and what's important it doesn't bubble.

I usually buy the Prestone kit that has all the temporary fittings, etc., plus the chemical and good instructions. You connect your building's water supply to a heater hose fitting with a garden hose.

If that kit doesn't do it, you're going to need a tear down.

I work at a chevy dealership and the 1995-2005 blazers and s10's are known for heater cores to plug up. We normally do a back flush the heater core along with the flush to remove gunk from heater core. Dont be suprised at all the gunk that comes out and you may even have to do it a few times to get it all.

We've always used one cup of sodium bicarbonate (baking soda) in a system that's filled with water , after draining all the antifreeze . After a fifteen minute drive , flush it out , rinse with water , drain and refill the system with antifreeze . Be safe...Bob.
