Hello,

The drain plug is on the lower left tank of the radiator here is a guide and a diagram (below) to help you see what to do.

I prefer to pull off the lower radiator hose. Drains a lot faster. To drain the block you should remove the block plugs on them if possible. If not just ad water and run it through the system. And re-drain and refill with proper coolant.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

It should be on the lower driver's side. It will look like a wing nut. If there isn't one, you may have to remove the lower radiator hose to drain the system.
