You *can* use distilled water, but it will be a bit more expensive and more difficult to get the water flowing thru to really flush it. I thought about the same thing when I did mine, and the garden hose worked best. If you remove the engine block drain plugs after you flush it, you will get practially all of the water out. Besides, if you do it every two years anyway, you'll be maintaing your system properly. Don't forget to pressure-bleed the radiator to get the air out after you fill it back up with coolant. Johnny 5518 > When flushing a cooling system should the new coolant be mixed with tap water or distilled water or does it really matter? Several years ago I had a head gasket failure on an aluminium block Cadillac engine and the service manager told me that if I had added GM Cooling System Seal Tabs(Part No. 3634621-a $4 part) with an engine flush every 3 or 4 years it would likely have eliminated a $1500 head gasket repair. Since the DeLorean engine block is aluminium should a similiar additive be used in it? Your thoughts will be appreciated. > > > --------------------------------- > Do you Yahoo!? > Win 1 of 4,000 free domain names from Yahoo!
