The concentrated corrosion inhibitors are diluted in a 50/50 mix of water and ethylene glycol. Use of Chevron Delo® FleetFix CME will not affect the freeze point of a cooling system for either conversion/maintenance/extender as long as the cooling system is currently at a 50/50 dilution.
Chevron Delo® Fleetfix CME is easy to use, simply add to the cooling system at the appropriate level, whether it is being used as an extender, maintenance fluid or converting a system to Chevron Delo® ELC. The Chevron Kool Tools Kit contains easy to use recommendation charts to assist with conversion/maintenance/extending Chevron Delo® ELC and protecting your cooling system.
Chevron Delo® FleetFix CME is available in 12/1 quart cases and can be used straight out of the box at the recommended level based on the cooling system requirements.
When using Chevron Delo® FleetFix CME properly, the Delo ELC coolant will have a service life of 1,500,000 miles / 2,400,000 km / 20,000 hours, or 8 years, if correct top-up and maintenance practices are followed.
The Chevron Delo® FleetFix CME product can be used by customers with on-road, off-road or industrial cooling systems.
WARNING: Even-though Chevron Delo® FleetFix CME contains glycol and water, it should not be used as a coolant/ antifreeze. Chevron Delo® FleetFix CME is to be used only as an extender, maintenance or conversion fluid.
Conversion: Chevron Delo® FleetFix CME is easy to use but requires a different process than the one used for a conversion done by draining, flushing and refilling or just draining and filling. The cooling system should be cool (< 100°F/38°C) before beginning the conversion procedure.
General Chevron Delo FleetFix CME conversion steps:
Step 1: Pre-test the coolant in-service that is going to be converted. During this step the coolant that is going to be converted to Chevron Delo® ELC needs to be tested for freeze point, pH and nitrite levels using the Chevron Delo® ELC Coolant Maintenance Kit and Kool Tools reference materials. If the tested coolant passes, then go to step 2. If the coolant fails the pre-test, then the reason for failure should be identified and corrected. The cooling system should then be drained, flushed and refilled with a fresh charge of Chevron Delo® ELC Antifreeze/Coolant - Premixed 50/50.
Step 2: Add Chevron Delo® FleetFix CME should be added based on the cooling system capacity. One gallon (4 quarts) of Chevron Delo® FleetFix CME should be added for every 9–12 gallons (34-45 liters) of cooling system capacity. The chart below will help determine how much Chevron Delo FleetFix CME needs to be added.
Step 3: Take a sample of the converted coolant. This is done to ensure that the conversion process was done correctly. The post test Chevron Delo®will evaluate the converted coolant for freeze point, pH, nitrite and carboxylate levels. Carboxylates are the corrosion inhibitors found in Chevron Delo® ELC Antifreeze/ Coolant. The post test of the converted coolant will identify if the pre-test was done correctly and if enough Chevron Delo® FleetFix® CME was added. The results of the conversion test will provide instructions to the customer on how to solve any issues that might arise. Another benefit of the post conversion test is that it will provide to both the customer and Chevron a baseline of the converted coolant condition.
Step 4: Attach a Chevron Delo® ELC Premixed 50/50 Smartfill label. These are found in the Chevron Delo® ELC Coolant Maintenance Kit to show that the Radiator system has been converted to Chevron Delo®lo ELC Premixed 50/50. These labels should be attached to the coolant addition port and be visible to anyone doing cooling system maintenance. These labels should be attached to a clean surface to improve adhesion.
Extender: Chevron Delo® FleetFix CME is also specifically formulated to work with Chevron Delo® ELC and should be added at 750,000 miles / 1,200,000 km / 10,000 hours, or 4 years, in order to obtain a service interval of 1,500,000 miles / 2,400,000 km / 20,000 hours or 8 years.
Maintenance: Cooling systems converted to Chevron Delo® ELC will require the same maintenance regardless of the conversion method used. In general, there are two maintenance steps that are required when using Chevron Delo® ELC Antifreeze/Coolant - Premixed 50/50.
Step 1: Use only Chevron Delo® ELC Antifreeze/Coolant - Premixed 50/50 for top-up. If the Chevron Delo®ELC Antifreeze/Coolant - Premixed 50/50 has been mixed with another coolant (assuming less than 25% mixture in the cooling system), then Chevron Delo FleetFix CME can be added to help return the mixed coolant back to the performance properties of Chevron Delo® ELC Antifreeze/Coolant - Premixed 50/50.
Step 2: Check the freeze point, pH and nitrite levels of the coolant at least two times per year or at every PM. In order to reduce the likelihood of contamination/ dilution it is recommended that:
• All non- Chevron Delo® ELC coolants are to be removed from the maintenance shop.
• All chemical water filters or liquid SCAs are to be removed from the maintenance shop.
• Use the Chevron Delo® ELC Coolant Maintenance Kit to help set up a best in class coolant maintenance program to achieve the optimal performance life of Chevron Delo® ELC Antifreeze/Coolant - Premixed 50/50. If a fleet is having problems with contamination/ dilution of Chevron DeloChevron Delo® ELC with other products, then the customer should consider the use of one of these approved methods for testing:
• On-site testing options. Use the Chevron Delo® FleetFix carboxylate test strips to check carboxylate levels. If this fails, then move to the Chevron Delo® FleetFix ELC Dilution test kit to check level of contamination and determine the correct steps for fixing the coolant system.
• Mail-in testing. Mail-in coolant sample kits are available through Chevron or its Lubricant Marketer channels. Each kit contains 10 tests. Two testing levels are available. The Extended Life Coolant Advanced program will evaluate the coolant sample for pH, freeze point, % water, nitrite, carboxylates, chloride, silicate, phosphate, molybdate and various metals.
