I followed the tutorial over @ Dgiant. The whole procedure went smooth as silk. I recommend doing what he says in regards to removing the hoses and flushing. After running the "Shout" through, lots of orange crap came out. Especially out of the heater core hoses.

I opted NOT to do the citrus flush. I also did a complete fresh water flush 2 times (removing the hoses and flushing with fresh water every time).

I did all the above with my old rad. Then replaced the rad. after the flush was complete.

The job was really easy but a little time consuming. It was a PITA to remove the hose down behind the oil filter and I had a hard time pulling the "block drain" without getting scalded with hot water. If you can get in the right position it is cake, just be careful.

I had no problem with "burping". If you have the problem you can put the car up on ramps or go for a quick drive and re-fill.

You are correct about filling and watching with the cap off. Just watch your engine temp. If the water/coolant starts to lift out... You waited too long.
