Typical characteristics

Manufacturer's description

Cat ELC Extender is an additive used with Cat ELC (Extended Life Coolant), the extended-life coolant developed, tested and approved by Caterpillar for Cat and original equipment manufacturer (OEM) diesel and gasoline engines that use the organic acid technology corrosion-inhibitor system. Cat ELC Extender is added only once during the coolant's service life to renew the inhibitor package: it exceeds Cat EC-1 performance requirements and protects against cylinder liner/block pitting and cavitation erosion. It should be added at 6,000 hours (or 500,000 km / 300,000 miles for Cat-powered on-highway trucks) — roughly the mid-point of the coolant's life — after which Cat ELC performance is ensured to the full 12,000-hour or 1,000,000 km (600,000 mile) life. The system should then be drained and flushed with clean water at the end of that interval; no cleaning agents are needed. Cat ELC meets or exceeds Cat EC-1, ASTM D-3306, ASTM D-6210, SAE J1034 and TMC RP-329/RP-338, and also meets the performance requirements of Cummins, Detroit Diesel, International, Mack and Volvo.

Applications

• Added to Cat ELC coolant already in service, to extend the coolant's life (see the ELC Extender/Flush interval schedule).

Performance & benefits

• Exceeds Cat EC-1 performance requirements.
• Protects against cylinder liner/block pitting and cavitation erosion.
• Only needs to be added once during the life of the coolant: at 500,000 km (300,000 miles) or 6,000 hours for Cat-powered on-highway trucks, and at 6,000 hours for commercial engines.
• Extends Cat ELC performance up to 1,000,000 km (600,000 miles) or 12,000 hours.
