Scotty, I tried your method twice and I'm not having any luck. When I put the hose in the radiator it pushed out all the liquid from the engine and pushed clear water into the radiator but when I put everything back together I try to dump a gallon of antifreeze in the radiator, it won't take it. It's full of clear water! I've even started the engine thinking it will empty the radiator into the engine and then I'll be able to dump the antifreeze in, but that won't work either. I've left the car parked until today when we finally have a good weather day and now I can't do this so the car is stuck in the driveway still. Please help!! Thank you!!
