ENGINE AR 5103473 - Caterpillar

Note: Ensure that the correct oil type label is applied to the oil filler cap.Coolant Recommendations
The following two coolants are used in Caterpillar diesel engines:Preferred - Caterpillar ELC (Extended Life Coolant).Acceptable - A Caterpillar DEAC (Diesel Engine Antifreeze/Coolant) or a commercial heavy-duty antifreeze that meets "ASTM D6210" specifications
The Caterpillar industrial engine must be operated with a 1:1 mixture of water and glycol. This concentration allows the NOx reduction system to operate correctly at high ambient temperatures.
Caterpillar recommends a 1:1 mixture of water and glycol. This mixture of water and glycol will provide optimum heavy-duty performance as an antifreeze.Ensure that the coolant fill rate meets the recommended coolant fill rate for the application.Glow Plug Control Unit for C3.4B Engines
