Default Re: Rusty Coolant

If you want to run straight water, you need to add a bottle or two of "Anti-Rust & Water Pump Lubricant". This stuff is getting harder to find because everyone runs antifreeze in modern cars now. NAPA used to carry it. Also, light grease the water pump fitting closest to the engine, even if you have a modern seal.
