So I followed the instructions that scottydogs laid out on how to flush the coolant. After draining as much coolant as possible from the radiator drain, I removed the tstat, put the housing back on, then removed the top radiator hose from the radiator. I had the top radiator hose drain into a PVC pipe and then to a bucket. I kept flushing until the water was clear, and then let the water pump finish pushing out the water. I even turned the heater on full blast to drain the heater core.
I re-attached the radiator hose, put in the new tstat and gasket.
So then I'm going to fill the radiator and it only takes about 1/2 gallon of antifreeze before it starts overflowing. It goes down some and then I start adding water. Maybe 1/4 of a gallon and it is now full.
I run the engine to open the tstat, and still water remains in the funnel going up and dow but never fully draining into the radiator.
I was expecting to use 1 gallon of antifreeze and 1 gallon of water, then top it off with 50/50, but it didn't even come close.
Any ideas?
