Impala coolant flush

[Drew99GT]

Anyone done a flush on the newer GMs with the 3.5L or 3.9L V-6s? Looks like the radiator drain plug is actually accessible on these cars!

Any tips or tricks? Thinking of flushing the Dex out and going with Peak Global Lifetime for an 07 Impala.

Thanks

Could always just pull the lower rad hose. A bit messy but it works. Had to do that on my sunire because my radiator drain is screwed up.

Is there a plug that drains the block?
