How to drain radiator 2008 buick lucerne
I looked at info for the v6. If you see a better way, certainly, use your own judgement.
There should be a small brass valve at the bottom corner of the radiator usually. If no luck just unclamp the lower radiator hose and pull it off the radiator. .
THERE,S no drain plug take the bottom radiator hose off the engine its much easier
