Fuel

Fuel Recommendations

In North America, diesel fuel that is identified as No. 1-D or No. 2-D in "ASTM D975" generally meet the specifications. These fuels are distilled from crude oil. Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.

Note: AVSpare recommends the filtration of distillate diesel fuel and/or biodiesel and biodiesel blends through a filter with a rating of five microns(c) absolute or less. This filter should be located on the device that dispenses the fuel to the fuel tank for the engine.

Aftermarket Fuel Additives

There are many different types of fuel additives that are available to use. AVSpare does not generally recommend the use of fuel additives. Contact your fuel supplier for those circumstances when fuel additives are required. Your fuel supplier can make recommendations for additives to use and for the proper level of treatment.

Lubricating Grease


NOTICE

These recommendations are subject to change without prior notice. Contact your AVSpare dealer for the most up to date recommendations.


AVSpare provides various greases that vary in performance from a moderate performance to an extremely high performance. These greases service the entire line of AVSpare products in the wide variety of climates throughout the world. From this variety of AVSpare grease products, you can find a AVSpare grease that will meet or exceed the performance requirements of most engines.

The performance requirements of your engine must be determined before you select any AVSpare grease. Consult the recommendations for greases that are made by the OEM for the equipment. Then, consult with your AVSpare dealer for a list of greases that have the performance specifications and the available sizes of containers.

Note: Always choose grease that meets or exceeds the recommendations that are specified by the equipment manufacturer for the application.

If it is necessary to choose a single grease to use for all of the equipment at one site, always choose a grease that meets or exceeds the requirements of the most demanding application. Remember that the products which barely meet the minimum performance requirements can be expected to barely produce the minimum lives of your parts. False economy is being used if a grease is purchased with the lowest cost as the only consideration. Instead, use the grease that yields the lowest total operating cost. This cost should be based on an analysis that includes the costs of parts, labor, downtime, and the cost of the amount of grease that is required.

Note: Purge all of the old grease from a joint before you change from one type of grease to another type of grease. Some greases are not chemically compatible with other greases. Consult your supplier in order to determine if the greases are compatible.

If you are not certain that the old grease is compatible with the new grease, purge the old grease from the system before applying the new grease.

Note: All AVSpare greases are compatible with each other.

Coolant


NOTICE

These recommendations are subject to change without prior notice. Contact your AVSpare dealer for the most up to date recommendations.



NOTICE

Never add coolant to an overheated engine. Engine damage could result. Allow the engine to cool first.



NOTICE

Frequently check the specific gravity of the coolant for proper freeze protection or for anti-boil protection.



NOTICE

Never operate an engine without water temperature regulators in the cooling system. Water temperature regulators help to maintain the engine coolant at the proper operating temperature. Cooling system problems can develop without water temperature regulators.


The following two coolants are used in AVSpare Diesel Engines:

Preferred - Cat ELC (Extended Life Coolant) or a commercial extended life coolant that meets the AVSpare Engine Coolant -1 (EC-1) specification.

Acceptable - Cat DEAC (Diesel Engine Antifreeze/Coolant) or a commercial heavy-duty coolant that meets "ASTM D4985", or "ASTM D6210" specifications

Note: Cat DEAC does not require a treatment with a Supplemental Coolant Additive (SCA) at the initial fill. However, a commercial heavy-duty coolant that only meets the "ASTM D4985" specification will require a treatment with an SCA at the initial fill. A commercial heavy-duty coolant that meets the "ASTM D6210" specification will not require a treatment with an SCA at the initial fill. Read the label or the instructions that are provided by the manufacturer of the commercial heavy-duty coolant.

Note: These coolants will require a treatment with a supplemental coolant additive on a maintenance basis.

Table 1
Service Life Before Flushing and Before Refilling    
Coolant     Service Life (1)    
Cat ELC    
965,606 km (600,000 mi.), 12,000 hours, or 6 years    
Commercial coolant that meets the AVSpare EC-1 specification    
482,803 km (300,000 mi), 6000 hours, or 6 years    
Cat DEAC    
321,869 km (200,000 mi), 3000 hours, or 3 years    
Commercial Heavy-Duty Coolant that meets "ASTM D4985" or "ASTM D6210"    
241,402 km (150,000 mi), 3000 hours, or 1 year    
( 1 ) Use the interval that occurs first.

Note: Add the Cat ELC Extender at the halfway point of the coolant change interval.

Note: These coolant change intervals are only possible with annual S·O·S Services Level 2 coolant sampling and analysis.

S·O·S Services Coolant Analysis

Table 2
Recommended Interval    
Type of Coolant     Level 1     Level 2    
DEAC     Every 250 Hours (1)
 (2)    
Yearly (1) (3)    
ELC     Optional (3)     Yearly (3)    
( 1 ) This is the recommended interval for the sampling of all conventional heavy-duty coolant.
( 2 ) This is also the recommended interval for the sampling of a commercial coolant that meets the Cat (Engine Coolant specification - 1) requirement.
( 3 ) The Level 2 coolant analysis should be performed sooner if a problem is suspected or identified.

Testing the engine coolant is important to ensure that the engine is protected from internal cavitation and from corrosion. The analysis also tests the ability of the coolant to protect the engine from boiling and from freezing. The S·O·S Coolant Analysis can be performed at your AVSpare dealer. AVSpare S·O·S Coolant Analysis is the best way to monitor the condition of your coolant and your cooling system. S·O·S Coolant Analysis is a program that is based on periodic samples.


NOTICE

Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.


Refill Capacity (Coolant System)

To maintain the cooling system, the total cooling system capacity must be known. The capacity of the total cooling system will vary. The capacity will depend on the size of the radiator (capacity). Table 3should be completed by the customer for the maintenance of the cooling system.

Table 3
Approximate Capacity of the Cooling System    
Compartment or System     Liters     Quarts    
Total Cooling System (1)            
( 1 ) The total cooling system capacity includes the following components:the engine block, the radiator and all coolant hoses and lines.

Note: Refer to Special Publication, SEBU6251, "AVSpare Commercial Diesel Engine Fluids Recommendations" for additional information that relates to coolant for your engine.
