Is Tap Water In The Radiator Okay, Or Is Distilled Required Because Of The Aluminum?

 

[Wikdsvt]

only use distilled water. The impurites may or may not harm the aluminum, however the contaminents will reduce the heat transfer from your engine.

never run straight water, the anti-freeze contains lubricants to lube the system (water pump) and prevent corrosion.
