High performance extended life antifreeze/coolant

Texaco ® Delo ® XLC Antifreeze/Coolant is a high performance long-life coolant formulated to help protect engines from freezing and boiling while offering advanced cooling system corrosion protection, including high temperature corrosion resistance in modern aluminium engines. Delo XLC Antifreeze/Coolant is an ethylene glycol based fluid formulated with advanced non-depleting corrosion inhibitor technology. It is designed to offer long, low maintenance service life and is available as a concentrate, or premixed in concentrations of 40/60, 50/50 and 55/45 (grades dependent on region/country).

Benefits

  • Advanced non-depleting corrosion inhibitor technology promotes extended low maintenance service life and system uptime
  • Mixed fleet applications offer at least 650,000 km in trucks and buses and up to 32,000 hours in stationary engines*
  • Promotes reliability and corrosion protection in thermostats, radiators, water pumps and other vulnerable cooling system components
  • High performance silicate- and phosphate-free formulation contributes to reliable hard water stability
  • Aids high temperature corrosion protection in modern engines, helping reduce maintenance, downtime, cost, and waste

Applications

  • Delo XLC Antifreeze/Coolant is recommended for use in heavy duty and stationary engines that require improved heat transfer performance, cavitation protection and long-life cooling system protection
  • No compatibility problems should be encountered with seals, hoses and plastic components, provided that the operating temperature is within the range appropriate for that material type
  • This product is not to be used to protect the inside of potable water systems against freezing
