COOLANTS FOR DETROIT DIESEL ENGINES
The intent of this bulletin is to provide the requirements, directions and information required to ensure cooling system protection for Detroit Diesel engines. These recommendations are general rules and reflect years of experience, technology research, and product development. Specific concerns not covered by this publication should be addressed to your local Detroit Diesel representative.
The coolant used in Detroit Diesel engines must meet the following basic requirements:
■ Provide an adequate heat transfer medium.
■ Protect against cavitation damage to both cylinder liners and water pumps.
■ Provide a corrosion/erosion-resistant environment.
■ Prevent formation of scale or sludge deposits.
■ Be compatible with cooling system hose and seal materials.
■ Provide adequate freeze protection.
Corrosion inhibitor in conventional coolant provides the following protection: Inhibitor Protection
Azoles Copper alloys
Borate pH buffer
Silicate Aluminum and solder
Nitrite Cast iron corrosion and cavitation
Nitrate Light alloys
Corrosion inhibitor in organic acid coolant provides the following protection: Inhibitor Protection
Azoles Copper alloys
Carboxylic and dibasic acids Corrosion protection for aluminum, solder, light alloys and cavitation/corrosion for cast iron
The rest of this bulletin will describe the requirements for the proper usage of the water, antifreeze, and corrosion inhibitors. It will also describe the coolants and additives that are not recommended by Detroit Diesel and have been proven harmful to Detroit Diesel engines.
DETROIT DIESEL ENGINE INITIAL FILL COOLANTS
Listed in Table 1 are the approved and preferred coolants for each engine series. This section details the proper formulation of these coolants. Once in use, these coolants should be maintained according to procedures found in this publication. Refer to section titled “MAINTENANCE.”
Ethylene Glycol / Water + SCA Inhibitor
Propylene Glycol / Water + SCA Inhibitor
These products are available as fully formulated, Phosphate-Free, Extended Service Interval (ESI) coolants. They are commercially available from Detroit Diesel (recommended) and other manufacturers, as either a concentrated antifreeze or as a pre-mixed antifreeze. The pre-mixed antifreeze is ready for use, while the concentrated coolant must be mixed with water prior to use. Do not use this type of coolant in Series 2000 and Series 4000 marine engines.
Detroit Diesel POWER COOL® Engine Coolant (P/N 23512138) is the preferred ethylene glycol coolant as listed in Table 1. If other commercial brands of ethylene glycol are used, they must be equivalent to POWER COOL. Detroit Diesel does not market a propylene glycol coolant. If a propylene glycol coolant is used, it must also meet the following requirements:
■ Fully formulated ethylene glycol-based, low silicate antifreeze or coolant must meet TMC RP-329 “Type A” requirements.
■ Fully formulated propylene glycol-based antifreeze or coolant must meet TMC RP-330 “Type A” requirements.
NOTE:
Fully formulated antifreeze does not require a dosage of SCA prior to initial use.
Mixing EG or PG Antifreeze and Water
If a concentrated Ethylene Glycol (EG) or Propylene Glycol (PG) antifreeze is purchased, mix the antifreeze with water meeting the required quality standards and fill the cooling system. Refer to section titled “Water Requirements.” If a pre-diluted, fully formulated coolant is purchased, simply fill the cooling system.
For best overall performance, a coolant consisting of 50% concentration of antifreeze (50% antifreeze, 50% water) is recommended. An antifreeze concentration of over 67% (67% antifreeze, 33% water) is not recommended due to poor heat transfer, reduced freeze protection (IEG only), and possible silicate dropout. An antifreeze concentration below 33% (33% antifreeze, 67% water) offers too little freeze and/or corrosion protection and is not recommended.
See Figure 1 for ethylene glycol-based coolant concentration versus freezing and boiling temperatures.

Type A (50/50 Coolant/Water Mixture)
Recycled Antifreeze
Antifreeze or coolant recycled by reverse osmosis, distillation, and ion exchange, properly re-inhibited to meet TMC RP-329 “Type A” or RP-330 “Type A” requirements has been demonstrated to provide service equivalent to virgin antifreeze. Recycled antifreeze or coolants of these types are preferred. Other recycled coolants, especially coolants recycled through filtration processes, are not recommended.
Ethylene Glycol / Water + OAT / NOAT Inhibitor
Propylene Glycol / Water + OAT / NOAT Inhibitor
Ethylene glycol and propylene glycol are also available with an Organic Acid Technology (OAT) corrosion inhibitor package. These coolants require less maintenance over the useful life of the engine. The cooling system should either be equipped with a “blank” coolant filter or the coolant filter and piping may be omitted from the system.
OAT fully formulated types of antifreeze are available as concentrated and pre-mixed. Concentrated antifreeze should be mixed at 50% (50% antifreeze/50% water). OAT coolants should not be mixed with conventional coolants. If OAT and conventional coolants are mixed, no damage will result, but the long-life advantages of the OAT coolant will be lost. In this event, the coolant should be maintained as a fully formulated ESI (Extended Service Interval) coolant, not as an OAT coolant.
Detroit Diesel markets OAT-inhibited ethylene glycol coolants—DDC POWER COOL Plus and POWER COOL Plus Marine (30% glycol, 70% water). POWER COOL Plus coolants contain all of the required inhibitors. If a non-DDC® OAT antifreeze is used, it must conform to TMC RP-338 specification. Do not add extender to new OAT antifreeze or coolant.
Water Only + SCA
Water Only + OAT Inhibitor
In warm climates where freeze protection is not required, water only with corrosion inhibitors is approved for use. Water-only systems need to be treated with the proper dosage of corrosion inhibitors. Detroit Diesel-approved conventional SCA or OAT corrosion inhibitors must be added to the water to provide required corrosion and cavitation erosion protection. Initial fill options are listed in Table 1. OAT inhibitors such as POWER COOL Plus 6000 are available for water-only systems. OAT inhibitor should be mixed at 7.5% by volume with water. A listing of POWER COOL products is provided at the end of this brochure. Refer to section titled “POWER COOL ENGINE PRODUCTS.”
Conventional SCA (POWER COOL 3000) can also be used to protect the engine. Listed in Table 3 are POWER COOL 3000 coolant concentration limits.
Boron | 125-500 PPM |
Nitrite | 800-3200 PPM |
Nitrate | 0-1000 PPM |
Silicon | 50-400 PPM |
Phosphorous | 0 PPM |
pH | 8-11.0 |
Table 3. POWER COOL 3000 Coolant Concentration Limits, (5% POWER COOL 3000,
95% water)
POWER COOL 3000 SCA inhibitors should be mixed at 5% by volume with water (1 quart per 5 gallons of water). These additions can be made by adding liquid SCAs available in a variety of sizes. Coolant filters are also available for different cooling system capacities. These filters release the proper amount of SCA at initial fill. A listing of coolant elements matched with the cooling system capacity for water-only systems is provided at the end of this brochure.
NOTE:
In Series 2000®, 4000™, and 149 engines, use a mix of 3% POWER COOL 3149 silicate- free SCA and 3% POWER COOL 3000 in the coolant water. Use only OAT (POWER COOL Plus 6000 or POWER COOL Plus Marine) inhibitors in Series 60, Series 2000 and Series 4000 marine engines.
Non-marine water-only systems for Series 2000, Series 4000, and all Series 149 engines should be charged with 5% POWER COOL 3149. Listed in Table 4 are the coolant concentration requirements for these engines. Glycol (EG or PG)-based coolant in marine applications (Series 149, 2000 and 4000) may cause overheat problems if raw water temperature is above 80°F (27°C).

Water Requirements
Distilled or de-ionized water, which eliminates the adverse effects of minerals in tap water, is preferred. High levels of dissolved chlorides, sulfates, magnesium, and calcium in some tap water causes scale deposits, sludge deposits and/or corrosion. These deposits have been shown to result in water pump failures and poor heat transfer, resulting in over-heating. If tap water is used, the mineral content in the water must be below the maximum allowable limits listed in Table 5.
NOTICE:
Do not add additional SCA to new, fully formulated antifreeze or coolant. This can result in drop-out and/or the formation of deposits.

Figure 3. Procedure for Evaluating Water
COOLANTS NOT RECOMMENDED
The following describes the types of coolants not recommended for use in Detroit Diesel engines:
■ All types of antifreeze and coolants containing phosphorous should be avoided. Drop-out, overheating, and water pump seal failures can result from use of coolant or inhibitor packages based on phosphate.
■ Automotive type coolants generally contain high levels of phosphate and silicate, offer no
liner pitting protection and are not suitable for use in Detroit Diesel engines.
■ Methyl alcohol-based antifreeze must not be used in Detroit Diesel engines because of its effect on the non-metallic components of the cooling system and its low boiling point.
■ Methoxy propanol-based antifreeze must not be used in Detroit Diesel engines because it is not compatible with fluoroelastomer seals found in the cooling system.
■ Glycol-based coolants formulated for heating/ventilation/air conditioning (HVAC) should not be used in Detroit Diesel engines. These coolants generally contain high levels of phosphates, which will form deposits on hot internal engine surfaces, reduce heat transfer, and cause water pump seal leaks.
ADDITIVES NOT RECOMMENDED
The following describes the types of additives not recommended for use in Detroit Diesel engines:
Soluble Oils
■ Soluble oil additives are not approved for use in Detroit Diesel engine cooling systems. A small amount of oil adversely affects heat transfer. For example, a 1.25% concentration of soluble oil increases the fire deck temperature 6%. A 2.50% concentration increases the fire deck temperature 15%. The use of soluble oil additives may result in engine overheating and/or failure.
Chromates
■ Chromate additives are not approved for use in Detroit Diesel engine cooling systems.
Chromate additives can form chromium hydroxide, commonly called “green slime.” This, in turn, can result in engine damage due to poor heat transfer. Cooling systems operated with chromate-inhibited coolant must be chemically cleaned with POWER COOL Twin Pack cooling system cleaner/conditioner (or equivalent sulfamic acid/sodium carbonate cleaner) and flushed.
MAINTENANCE
This section describes procedures needed for maintaining coolant level and proper concentration.
Topping Off Coolant
Coolant level should be checked at each maintenance interval. If topping off is needed, add coolant which is identical to the initial fill coolant.
Supplemental Coolant Additives for Fully Formulated Coolant
The concentrations of some inhibitors will gradually deplete during normal engine operation. SCAs replenish the protection for cooling system components. The coolant must be maintained with the proper concentration of SCA. Detroit Diesel POWER COOL maintenance products are recommended for use in all Detroit Diesel engines.
The proper application of SCA will provide:
■ pH control.
■ Restored Inhibitor levels to prevent corrosion.
■ Water-softening to deter formation of mineral deposits.
■ Cavitation protection to protect internal engine surfaces exposed to coolant.
Check the nitrite concentration at the regular intervals listed in Table 6 with a Power Trac 3-Way
Test Strip.
Service Application | Inhibitor Test Interval |
On-Highway Trucks and Motor Coaches | 20,000 Miles (32,000 Kilometers) |
City Transit Coaches, Pick-up and Delivery, Short Trip, and Emergency Vehicles | 6,000 Miles (9,600 Kilometers) or three months, whichever comes first |
Industrial, Marine, Generator Set, and all other Applications | 200 Hours (300 Hours for Series 149) or yearly, whichever comes first |
This table does not apply to organic acid technology-based inhibitor systems.
Table 6. Required IEG and IPG Coolant Inhibitor Test Intervals for Traditional
Nitrite-based SCA
Listed in Table 7 and listed in Table 8 are concentration limits. Additional SCA must be added to the coolant when it becomes depleted, as indicated by a nitrite concentration of 800 PPM or less. If the nitrite concentration is greater than 800 PPM, do not add additional SCA. If the nitrite concentration is above 3200 PPM, the system is over-inhibited. The system should be partially drained, and filled with a 50/50 mix of water and EG or PG. In this case the EG or PG should contain no inhibitors, and should conform to ASTM D4985 or ASTM D5223. This will dilute the over-concentrated inhibitors.

Table 8. POWER COOL 3149 Coolant Concentration Limits
Silicate-Free SCAs for Series 149, 2000 and 4000 Construction and Industrial Engines
The high thermal gradients experienced by coolants in high horsepower construction and industrial engines causes silicates to drop-out if maintained with traditional SCAs. This drop-out accumulates in the radiator tubes, reducing heat transfer and overheating the engine. For this reason, Detroit Diesel has developed an SCA package that is formulated without silicates. The DDC-formulated package is POWER COOL 3149 Silicate-Free SCA. The POWER COOL 3149 should be mixed at 5% by volume with water, or 1 quart to 5 gallons of water. Series 149, 2000 and 4000 C and I engines should be initially charged with conventional SCAs (such as POWER COOL 3000) at initial fill but should be maintained with the silicate-free SCA.
NOTICE:
Phosphate-based inhibitor packages should not be used. Overheating and water pump seal failures will result if used.

Table 9. Coolant Maintenance Intervals
SCA Test Procedures
Nitrite concentration is an indication of the overall coolant inhibitor concentration in non-OAT formulations. Coolant must be tested for nitrite concentration at the regular intervals listed in Table 9. Power Trac 3-Way Test Strips (or equivalent) are recommended. Nitrite levels must be within the ranges listed in Table 7 and listed in Table 8.
Use Detroit Diesel Power Trac 3-Way Coolant Test Strips to measure nitrite and glycol concentrations. Refer to section titled “POWER COOL ENGINE PRODUCTS” for part numbers. Cavitation/corrosion protection is indicated on the strip by the level of nitrite concentration. Freeze/Boil-over protection is determined by glycol concentration.
Use the test strips as follows:
For best results make the tests while the coolant is between 50°-140°F (10.0°-60°C). Wait at least 60, but not longer than 75 seconds before reading the nitrite level. Promptly replace and tighten container cap after each use. Discard unused strips if they have turned light pink or tan.
A factory coolant analysis program is available through authorized Detroit Diesel service outlets. Refer to section titled “POWER COOL ENGINE PRODUCTS” for part numbers. To verify coolant acceptability, submit a sample for coolant analysis every three (3) years, 300,000 miles, or 6,000 operating hours, whichever comes first.
NOTICE:
Failure to properly maintain coolant with SCA can result in damage to the cooling system and its related components. Conversely, over concentration of SCA inhibitor can result in water pump seal leaks and poor heat transfer, leading to engine damage. Always maintain concentrations at recommended levels. Do not use traditional SCAs with NOAT coolant.
NEED RELEASE COOLANT FILTERS (Not Available in OAT/NOAT Applications) Spin-on coolant filters are available for Series 50 and 60 engines. Membranes in the filters release SCAs before the coolant approaches a corrosive condition, protecting the engine from corrosion. The elements release the SCA charge as needed, as opposed to the maintenance SCA elements, which instantaneously release the SCA charge. Need Release coolant filter elements should be replaced after 1 year, 120,000 miles (192,000 km) or 2,000 operating hours, whichever comes first.
DROP-OUT
Excessive amounts of some inhibitors in the engine coolant can cause a gel or crystalline deposit that reduces heat transfer and coolant flow. The deposit, called “drop-out,” takes the color of the coolant when wet, but appears as a white or gray powder when dry. It can pick up solid particles in the coolant and become gritty, causing excessive wear of water pump seals and other cooling system components. The wet gel can be removed by using a non-acid (alkali) type heavy-duty cleaner such as Detroit Diesel POWER COOL On-Line Cleaner (sodium nitrite/sodium tetraborate). Refer to section titled “POWER COOL ENGINE PRODUCTS” for part numbers. If the gel is allowed to dry, it is necessary to disassemble the engine and clean it with a caustic solution or physically clean individual components.
COOLANT EXTENDER INHIBITOR ADDITIVE FOR “OAT” COOLANT
The inhibitors in OAT coolant must also be maintained, but less often than traditional SCA-type coolants. The concentrations of some inhibitors will gradually deplete during normal engine operation. Fleet testing has determined the rate of depletion of these inhibitors. Using this data, an extender package was developed which should be added to the coolant at 0.6% by volume at 300,000 miles (480,000 km), 2 years or 10,000 hours, whichever comes first. A properly maintained OAT-inhibited coolant will last 4 years, 600,000 miles (960,000 km), or to engine overhaul, whichever comes first, at which time the coolant should be drained. This dosage should be added to the water-only and the glycol systems at the same interval.
NOTE:
Do not use traditional SCAs in OAT coolant, and do not use OAT extender in traditional coolants.
DETROIT DIESEL COOLING SYSTEM MAINTENANCE PRODUCTS
Detroit Diesel POWER COOL SCAs are water-soluble chemical compounds. These products are available in coolant filter elements, liquid packages, and in fully formulated POWER COOL antifreeze.
Coolant Filter Elements
Replaceable coolant filter elements (spin-on canisters) are available in various sizes suitable for cooling systems of varying capacity. Selection of the proper element size is vital when pre-charging non-fully formulated coolant (i.e. water) at initial fill, and at maintenance intervals. A fully formulated antifreeze must NOT have SCA added at initial fill. Do not use SCA-containing filters with OAT antifreeze or coolant. The need for maintenance elements is determined by the results of the nitrite concentration test performed at each cooling system service interval in systems using traditional/conventional formulations. Do not automatically install maintenance elements at maintenance intervals unless the nitrite concentration level falls below 800 ppm.
Liquid SCA
POWER COOL 3000 SCA is more compatible with hard water than POWER COOL 2000 SCA.
Cleaners
Use POWER COOL Liquid On-Line Cleaner for light deposits. Use POWER COOL Dry Chemical
Cleaner/Conditioner for heavy deposits or scale.
SUMMARY OF COOLANT RECOMMENDATIONS
Observe the following recommendations for proper coolant maintenance:
CAUTION:
To avoid possible personal injury (scalding, eye injury) from the hot coolant, never remove the cooling system fill (pressure) cap while coolant is hot. The system may be under pressure. Remove the cap slowly and only when coolant is at ambient temperature.
