Evans - Heavy Duty Thermal Coolant (HDTC)
Evans HDTC is the waterless cooling solution for heavy duty diesel applications. It features a huge separation between the operating temperature of the coolant and its boiling point. HDTC can control metal temperatures at coolant temperatures that are well above the boiling point of water. With engine metals protected at higher coolant temperatures, fan turn-on temperatures can be safely increased. Released from the burden of avoiding the boiling point of water, HDTC waterless coolant enables the safe use of higher coolant temperatures and sharply reduced fan usage. Thousands of dollars in fuel savings annually result from that technique.

- Lasts the lifetime of the engine.
- Increase Efficiency 3% - 7%.
- End after-boil
- Reduced toxicity
Coolant Filters
Converting to Evans HDTC requires changing to a blank coolant filter.
Thermostats
To acheive increased fuel economy Evans suggests installing a higher temperature thermostat.
- Boiling point: 190.6 °C (375 °F), at zero psig
- Freezing point: Below -40 °C (-40 °F)
- Specially formulated for heavy duty engines.
- Stops cylinder liner cavitation erosion.
- Lasts the lifetime of the engine if uncontaminated by water.
- The coolant temperature is not limited to the boiling point of water.
- Ends afterboil.
- The cooling system develops less pressure because there is no vapor component.
- Permits fuel saving strategies not available with water-based coolants.
