All,
I've been bringing my Z back to life slowly and methodically. For the past week, I've been trying to flush the coolant from the system given it was a dark rusty brown, bubbly at first. I've now flushed the system some 30 times, filling with water, running for 10-20 minutes, cooling, and draining. I've also used Blue Devil TWICE but I sill get an ice tea discharge when I draining, similar to the 1st cup in the photo. At first the car ran hot but have gotten it to the point where it's now running normal. That said, could the radiator be toast rust wise? Do I need to undo the block plugs and flush out the block? Or just keep filling, running, and draining another 30 times? Thanks for all your help to date!
