Is there a drain plug on radiator on the 2004 Buick Regal? How do I change the coolant?

In times past, cars and trucks had a drain plug to drain the coolant out. I did not see one and the bottom hose on the radiator seems to ber very difficult to get to. How do you flush the coolant out to replace it?Is there a drain plug on radiator on the 2004 Buick Regal? How do I change the coolant?Spend 60-70 bucks and let a shop do a coolant exchange for you-

Your going to do a drain and fill - theres still old coolant in the hoses, block and heater core.

A shop will do a 100% coolant exchange and save you time and aggrevation!

Good Luck
