Probably equally important is a proper drain and flush of the old coolant.Įdit: I would ask Caterpillar tech support why their coolant is so bloody expensive and ask them to explain why it is worth the extra money. Since it is your employers truck and your employers money, barring any completely conclusive facts to the contrary I would use the CAT coolant. Container size availability will vary by region. Thats because your machine came with Cat Extended Life Coolant (ELC TM). ELC Extender is added at the half life of the coolant 500,000 km (300,000 miles) for truck engines and 6,000 hours for other engines. 9 gal/min (163 l/min) Relief Valve Pressure: 2250 psiSpecs for the. Cat ELC for Maximum Coolant Life Cat DEACTM 3000 Hour Life 322,000 km (200,000 miles) or 3 years. If you use the cheap coolant and something like the water pump should fail for some completely unrelated cause, who is going to have fingers pointed his direction? To obtain a freeze point of -52° C (-62° F) add one liter (gallon) to each 5 liters (gallons) of Cat ELC 50/50 premix. I hate to even bring this topic up, but it's part of the reality we live in. We don't 100% know and it's not your money you are to some extent gambling with. The extra money may be literally down the drain or it may be a very good investment in the service life of the engine. Isn't the coolant service life something like 750,000 miles? The extra cost of the CAT coolant is completely negligible on a cost per mile basis. Speaking only for myself, if I was charged with maintaining a truck owned by my employer I would run the CAT coolant. I believe Caterpillar was involved in the initial research involving Diesel cylinder liner cavitation erosion. Part of the reason the CAT coolant costs 3 times as much may be due to the CAT name but part of the cost may also be for superior coolant - I don't know for sure. Use ULTRA POWER RED ELC 50/50 exclusively for top-off, as needed.George, I have an older Ford Diesel pickup and I also struggle with coolant specs, although on a smaller scale and with my own money. Product colored purple for easy recognition. Follow vehicle or equipment owner’s manual for recommended maintenance guidelines, including proper coolant levels and instructions for coolant top-off. The new Shell Ultra ELC is yellow which is nitrate free and is only being used in the new international maxxforce engine, as well as the cat truck and is better for the metals being used in the. The two that I know are molybdate based are the Rotella Ultra and Delo. That being the case, it may or may not matter to you but the red CAT ELC is a carboxylate based system. ULTRA POWER RED ELC 50/50 is carefully balanced (prediluted) with pure deionized water to ensure optimum freezing and boiling points and eliminates system deterioration caused by poor water quality, DO NOT ADD WATER. there DEAC is purple which Cats equivalent to green coolant. Wingnut-You are certainly correct that any good ELC coolant is far better than what we have now.
