Changing Rad. & Heater core...

I'm hopefully going to be changing my radiator, tstat, upper and lower hoses and heater core this weekend. Are there any tips you guys can give me to make the install go a bit more smoothly. Past experiences you can draw on and say look out for this? My grandpa is going to be helping me, and has a pretty good knowledge of engine work/upgrade. This will hopefully help my overheating problems and the smoke thru the dash. Thanks for any info/ help.

Do NOT buy the "flush" crap. It can only cause problems later. (it's an acid) Before you change everything you want to....
Drain and refill with plain H2O.
Run until up to temp.
Repeat as many times as necessary until it's clean water coming out.
Then do it a couple more times.
NOW you can change out what you want to.
After you put it back together....
Flush one more time.
Then refill with coolant and check mixture with tester.
Just remember that the block still has a bunch of pure water in it, so it will take a little more antifreeze in the mix to get the % right than a normal "coolant change".
