BOOM GP 3039126 - Caterpillar

At operating temperature, the engine coolant is hot and under pressure.Steam can cause personal injury.Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand.Remove the fill cap slowly to relieve pressure.Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.
Use 8T-5296 Test Kit in order to check the concentration of the coolant.

1.18 L (40 oz) or one unit of both 3P-2044 and 6V-3542     two units of 111-2371 (3)    
( 1 ) Use a Caterpillar SCA when you do not use a Caterpillar Antifreeze.
( 2 ) Do not exceed the 6 percent maximum concentration. Check with the supplemental coolant additive test kit.
( 3 ) Element Assembly
Do not exceed the recommended six percent supplemental coolant additive concentration. Excessive supplemental coolant additive concentration can form deposits on the higher temperature surfaces of the cooling system, reducing the engine's heat transfer characteristics. Reduced heat transfer could cause cracking of the cylinder head and other high temperature components. Excessive supplemental coolant additive concentration could also result in radiator tube blockage, overheating, and/or accelerated water pump seal wear. Never use both liquid supplemental coolant additive and the spin-on element (if equipped) at the same time. The use of those additives together could result in supplemental coolant additive concentration exceeding the recommended six percent maximum.
Liquid Supplemental Coolant Additive

Open the access cover. Slowly loosen the radiator cap in order to relieve system pressure. Remove the radiator cap.
If necessary, drain enough coolant from the radiator in order to allow the addition of the liquid coolant additive.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Add 0.24 L (.50 pint) of cooling system additive for every 38 L (10 US gal) of engine cooling capacity.
Install the radiator cap. Close the access cover.Coolant Additive Element

Right side of engine
Open the access cover on the right side of the machine.
Close inlet valve (1) and outlet valve (2) .
Remove coolant conditioner element (3) with your hand or with a strap type wrench. Properly discard coolant conditioner element (3) .
Clean the element mounting base. Make sure that all of the old gasket is removed.
Replace the used coolant conditioner element with a new Caterpillar maintenance element.
Apply a light coat of clean engine oil
