Why do we have coolant? Heat Removal Corrosion protection Scale prevention Freeze & Boil protection Cavitation protection (Pitting) Center for Education Daimler Trucks 4
Cavitation / Liner pitting Center for Education Daimler Trucks 5
Cavitation EGR Coolers Today s engines, equipped with EGR Coolers, greatly increase our requirements to maintain and verify the condition of the coolant for maximum engine operation. Center for Education Daimler Trucks 6
Cavitation EGR Coolers Consider This: Exhaust Temperature may average Coolant Temperature would be at least The Differential Temp 700º F 195º F 500º F With this extreme in temperature differential, any deficiency of the coolant could easily result in the failure of the EGR system on today engines.

What HD Coolant Technologies are out there? Conventional (Automotive Types) Fully Formulated Coolants ELC or Organic Acids Coolants Center for Education Daimler Trucks 8
Do NOT Use The Following: Soluble Oil High silicate, automotive type antifreeze Chromate SCA Methoxy propanol-base coolant Methyl alcohol-base coolant Sealer additives or coolant containing sealer additives HVAC coolants Water with total hardness above 170 PPM Center for Education Daimler Trucks 9
Conventional Coolant (Automotive) Additives - (2.5%) Glycol - (47.5%) Corrosion protection. Phosphate, Nitrates, Silicates. Freeze and boil protection Water - (50%) Heat removal Center for Education Daimler Trucks 10
Maintaining Conventional Coolant (Automotive) Do NOT use in Mid-Range Diesel Engines Initial fill must be pre-charged with SCA s Every 15-20,000 miles (250 Hrs) check freeze point and SCA depletion using test strips Add SCA as test strip directs SCA can be added with liquid, service filter or extended service filter Drain, Flush and fill annually Center for Education Daimler Trucks 11
Fully Formulated makeup Additives - (2.5%) Glycol - (47.5%) Pre-Charged with SCA s (phosphate free) Freeze & Boil protection Water - (50%) Heat removal Center for Education Daimler Trucks 12
What is Fully Formulated Coolant? Phosphate free, Very low total dissolved solids (TDS) Meets TMC RP 329 and ASTM D6210 specs Common Brand Names: FleetCharge Alliance Prestone HD Colors: Depending on the manufacturer or OEM spec requirements Purple Pink Good for the life of the engine if properly maintained with Penray SCA s Center for Education Daimler Trucks 13
Maintaining Fully Formulated Coolant Initial fill is already pre-charged with SCA (no additional SCA are needed) Every 15-20,000 miles (250 Hrs) check freeze point and SCA using test strips Add SCA as test strip directs SCA can be added with liquid, service filter or extended service filter Center for Education Daimler Trucks 14
ELC Coolant makeup Additives - (2.5%) Carboxalate acid package Glycol - (47.5%) Freeze & Boil protection Water - (50%) Heat removal Center for Education Daimler Trucks 15
What is ELC (OAT, NOAT) Coolant? Primarily market colors: RED (Heavy duty) ORANGE (Light Duty) Common Brand Names: Cat ELC GM Dexcool Texaco ELC Powercool Plus Final Charge Shell ELC Fleetguard ES Optimax Center for Education Daimler Trucks 16
Maintaining Organic Acid (OAT, NOAT) Coolant Every 15-20,000 miles check freeze point and contamination level with Universal Test strip Extender may be added at 300,000 miles (6,000 Hrs) if coolant sample tests OK At 600,000 miles (12,000 Hrs) drain and flush Add nothing into the system except ELC or distilled water If system becomes contaminated with more than 15% of anything else (poor quality water, SCA, or other coolants) it must be drain and flushed or converted Center for Education Daimler Trucks 17
Test Strips Freeze Point SCA level Contamination (ELC Only) Center for Education Daimler Trucks 18
Refractometer Test Freeze point Must use with ELC Very accurate Center for Education Daimler Trucks 19
Liquid SCA s Nitrite / Borate technology Added to coolant @ 5% concentration (1 pint per 4 gallons) on initial fill Center for Education Daimler Trucks 20
Coolant Filters NF2999 (Blank) Contains no SCA NF3000 Contains 1 pint of Pencool 3000 Center for Education Daimler Trucks 21
Need-Release Extended Life Cooling System Filter Used with Fully Formulated Coolants Continuous cooling system protection Releases SCA into the cooling system as the corrosively of the coolant increases Lasts 150,000 miles, 15 months or 3,000 hours Replaces 8-10 ordinary filters Saves on labor and inventory Center for Education Daimler Trucks 22
Need Release Coolant Filter Separate Pucks dissolve as the coolant becomes more acidic, releasing SCA back into the coolant Center for Education Daimler Trucks 23
Converting ELC to Fully Formulated? Q: What happens if the bus is ordered with ELC, but I do not want to use ELC? A: Factory Fill ELC doesn t force you to continue to use the product. You don t even have to drain it. Just use conventional coolants for top-up and SCAs as recommended by the manufacturer. Q: What happens if I am on the road and cannot find my brand of ELC? A: Most ELC are compatible with most other brands. Using these other products will not diminish the performance of your coolant. Center for Education Daimler Trucks 24
