OAT Coolant

Thanks. That's what I wanted to hear from YOU.
Thanks again.

The flipmeister is of course right about using distilled water. To enhance its cooling property I swear by RedLine WaterWetter. At one time the local dealer sold this product. I realized a 15 degree drop in operating temperature, solely based on oil temp sensor, during the hottest of days here in Alabama. 190 degree oil temp versus 205 is also preserving the service life on my Amsoil. Normal day to day oil temps run 180-185.

BTW: While oil and water may not mix readily, the 185 oil temp reading coincides with the fan cut on timing. Soooo, the oil temp readily approximates water temperature.

Interestingly, wet linered engines (Rocket 3 included) transfer heat from combustion more readily than a parent bore (liner in cast block) engine and coolant temperature deviations are more pronounced.

Wet linered engiones benefit from an anti-cavitation additive or DCA treatment and it's readily available, off the shelf, at any heavy truck dealership because 95% of heavy trucks employ wet linered engines.

When it comes to heat transfer, there is a big difference between aluminum blocks and heads, and iron.

Also, aluminum/Nikasil bores are a big difference from iron/steel liners.
