Fresh Water Cooling Kits

No matter how long your engine has been running without closed cooling, now is the time to change. If you leave a metal tool outside, it's going to rust, so it doesn't happen only in salt water. Raw water cooled engines have 143 degree thermostats as salt crystallizes at temps above this. Your auto engine manufacturer never intended your engine to run this cold, so you are also loosing much power and fuel economy as well as engine life.
