I have a 2006 Malibu LT V6 3.5L. I plan to drain most of the coolant and refill it. But I checked my malibu's radiator, I can not find the drain plug. For most vehicles, there should be a drain plug at the bottom of the radiator.
Can anyboday teach me how can I drain and refill the coolant of my malibu?
Thanks

Disconnect the lower radiator hose from the radiator to drain. I thought I was crazy with the maintenance.:uhoh: Swapping the coolant already on a 2006? Why?

I found it. It's by the bottom coner of the radiator on the driver side. I just want to take care of car. I plan to drain the coolant every 50k to replace part of the coolant to void flush the cooling system every 100k.

I hear you on the maintenance. I'm surprised it still has a drain vlv on the radiator. GM decontented them on most makes/models.

That's news to me, they have a drain with a short hose, environmentally friendly. Pulling the hose makes a mess usually, unless you have a very large drain pan.
