rad flush

[minivan_don]

story starts with me taking the Goose into the local dealership to fix a very rapidly formed exhaust leak, but they mentioned doing the preferred maintenance as ive reached the 48k km service level.

the maintenance would include:- engine oil + filter (did last week)- engine air filter (did a few weeks ago)- COOLANT FLUSH- TRANY FLUID CHANGE + DIFF (?)- and a host of "top ups" and inpections including the brakes

since ive already done 1/2 of the work and dont feel like paying $400 for the rest ... i feel totally confident doing the rad and trany flush. i read mehdi's redline fluid change which was great for just the visual referrence, but any tips to flushing the rad? anyone done it yet?

ive done about 18 rad flushes on my 240 over the coarse of 2 engines, 2 rads, and a handful of rad removal/reinstalls ... so im not new.
