I might try that.
If you can get a garden hose and take off the lower hose, not sure if it will flow through the block or not but iirc ou WANT to fluch out the blcok too.. two things:
1) You will be AMAZED at how dirty the radiator was, do it "until the water runs clear"
2) After the waterr runs clear, as it will come out dirty for 3-5 minutes, even at full blast on hose (MAKE SURE YOUR ENGINE IS COOL so you dont run COLD garden hose water through the engine, just a thought!!) .. then, debate using a chemical flush since you just made the water run clear and you should be good to go.
did this on a high-mileage car, wanting to do it on mine.. but no garden hose, only a siphon and a garden hose will do it the ame, or better, IMHO.
(MUUCH faster too. "Until the water runs clear" is GREAT qway to get it clean!)
