Hey everyone,

I'm looking at flushing my cooling system in the coming days as I have the wrong coolant in my car and it's due to be done and was wondering what's the best way to drain the coolant and if the radiator has a drain plug under it? It's a WK LS1 so still has the big s*it coolant bottle near the passenger side strut tower instead of the VZ system with the cap on the radiator instead and a small overflow bottle next to the radiator.

Thanks
