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!?
