cooling system corrosion
im finding large deposits of corrosion around the inside of some cooling system parts. i know this is from regular tap water. but does anyone have a good method of getting this stuff out? maybe like something i could let the parts soak in?

Want to experiment? I was thinking about setting this up after my bare metal project on the 2runner (2nd generation). There are two steps.
step one: Harris International Labs product
http://www.evaporust.com/evaporustcsc.html
step two: Cortec Corporation product

Evaporust rust remover has made it to my, hard to get on, RECOMMEND list. I have tried it and it works well. I have not tried the radiator flush but I have added it to my TRY list.
I have not tried any of the BullFrog products but they come highly recommended. They are on my TRY list.
I would go for two sessions with the evaporust and then follow up with the BullFrog*
*The only research I still need to conduct is what coolant/antifreeze to go with. I'm looking at a Shell-Lubricants product, Rotella ELC sourced from SOPUS Products :

...buts thats just a starting point for my research log.

If you have alot of corrosion then the best thing to do is pull the radiator and take it to a shop and have it cleaned out, replace the water pump and thermostat and you should be alright after that.

I would just assume replace the rad for the $110 (+ - $20) it cost for an OEM style replacement...

The water jacket(S) in the lower intake are a return to the radiator via the thermostat and the supply to the heater.
If you've got mild deposits building up, a cooling system flush may take care of it. If it's severe, then more aggressive cleaning is needed... and that might mean several coolant flushes....
Nevermind... just realized it's a 3VZE... similar concept but I'm not an authority on the V6
