Customer Benefits

Delo XLC Antifreeze/Coolant products deliver value through:

• Optimal Service life
  Service life tested up to 960,000 kilometres/12,000 hours/ 6 years with no Extender needed.
• Excellent Protection
  Excellent protection against pitting, corrosion and erosion even on hard to protect metals like aluminium.
• Minimized maintenance and related costs
  Helps minimize the need for regular testing with proper top-up practices and helps eliminate the need for supplemental coolant additives.
• Heat Transfer
  Excellent heat transfer compared to silicate containing coolants.
• Hardware Life
  Helps maximize water pump life due to no silicate formula.
• Variable Applications
  Excellent protection for heavy duty engines where the OEM specifies a nitrite free coolant. Can be used in all heavy-duty engines using reduced emission protocols including or combining EGR, DPF or ACERT technologies. This product is recommended for mixed fleet applications.1
• Wide Temperature Applications
  Protection against winter freeze-up and summer boil-over.
• Biodegradability
  Biodegradable in its unused form.
• Compatibility
  Compatible with conventional antifreeze. Dilution with conventional antifreeze will reduce extended life benefits. Chevron recommends that this product not be diluted by more than 25% with other coolant formulations.
• Stability
  Can be stored for approximately 8 years in sealed containers without any effect on the product quality or performance.

Product features

• Delo XLC Antifreeze/ Coolant is a heavy-duty, ethylene glycol based engine coolant which incorporates patented organic corrosion inhibitor technology called aliphatic carboxylates.
• Delo XLC is a nitrite, nitrate, borate, phosphate, silicate, and aminefree formulation that is designed to provide maximum protection of the six basic metal alloys found in most heat transfer systems.
• Delo XLC products do not contain phosphates or silicates which are known to contribute to hard water scale issues.
• Delo XLC promotes maximum water pump seal life by eliminating inorganic corrosion inhibitors.
• Delo XLC has a recommended service life of 960,000 kilometers/12,000 hours/ 6 years. This product will not require the addition of SCA’s to achieve its recommended service life. Routine visual inspections, coolant topoff and annual testing are recommended to ensure maximum service life.
• Note: These products are not to be used to protect the inside of potable water systems against freezing.

Service Considerations

Product Dilution and Boil Over Protection Recommendations

For Delo XLC Antifreeze/Coolant – Concentrate

Boiling Protection, °C/°F (using a 15 lb pressure cap)

• 50% 1:1 (1 part antifreeze/1 part water) 129.4/265

Freezing Protection, °C/°F

• 33% 33:67 (33 parts antifreeze/67parts water) -19/-2.2
• 40% 2:3 (2 parts antifreeze/3 parts water) -26/-14.8
• 50% 1:1 (1 part antifreeze/1 part water) -37/-34.6
• 60% 3:2 (3 parts antifreeze/2 parts water) -50/-58

Notes

• Product concentrates should be agitated before use or dilution.
• Delo XLC Antifreeze/Coolant – Premixed 50/50 should be used as purchased.
  No dilution is recommended.
• For maximum protection against freezing in extremely cold areas, a 60 percent solution of Delo XLC Antifreeze/Coolant – Concentrate (3 parts antifreeze/2 parts water) can be used. Concentrations greater than 67 percent are not recommended.
• Always dispose of used coolant in accordance with local, state and federal guidelines.

Product Reference

• Note: Bitterant is a flavour aversive that may help reduce the accidental ingestion of this product. These products contain bitterant.
• Product Code: 510614 – Delo XLC Antifreeze/Coolant – Concentrate
• Product Code: 510609 – Delo XLC Antifreeze/Coolant – Premixed 50/50

The primary limiting factor in the shelf life of a coolant is silicate instability. Since silicate will eventually polymerize to silicate gel, silicate containing coolants have a shelf life of approximately 18 months. Delo XLC Antifreeze/Coolant is silicate-free and can be stored for 8 years, provided the container remains sealed. Product should be agitated before use.
