- Complete cooling system protection
Unique Carboxylate Technology inhibitor provides corrosion protection in aqueous solutions for all engine and cooling system metals, including aluminum, iron, steel, copper and solder alloys. The corrosion inhibitor prevents wet liner cavitation erosion and protects aluminum heat transfer surfaces. - Extended service life
Very low depletion rate of the organic acid inhibitor ensures long-term corrosion protection under all operating conditions. - Reduced maintenance costs
Unique Carboxylate Technology inhibitor system prevents wet liner cavitation erosion, and provides exceptional protection to aluminum surfaces under heat transfer conditions. - Saves time and money
Very low depletion rate and complete cooling system protection of the special organic acid inhibitor removes the need for supplementary additives for cavitation erosion protection, and reduces the need to regularly test inhibitor level and add extra additive to maintain the inhibitor concentration.
- Havoline® XLI Concentrate is an environmentally sensitive, coolant and corrosion inhibitor concentrate based on extended-life organic acid Carboxylate Technology.
- Havoline® XLI Concentrate, when mixed at 50% by volume with water, is suitable for use in automotive cooling systems, marine engines and stationary power generation where glycol-based antifreeze is not required.
- Engines not requiring the use of glycol-based antifreeze or freeze protection.
- Passenger car and light duty commercial vehicles with gasoline, diesel or gas engines.
- Heavy duty diesel engines in road transport vehicles.
- Agricultural and construction equipment, marine and stationary engines.
