When it comes to radiator coolant for a Komatsu 40 excavator, there are lots of things to consider. If you’re buying any kind of excavator, you might like to have some knowledge about what coolant type to use and why.

komatsu 40 excavator-Without the proper coolant, your engine can overheat and require costly repairs to fix.

Antifreeze, also called coolant, is an essential component of your car’s engine. It helps to keep it from overheating and freezing. According to the car experts at Edmunds.com, “Without the proper coolant, your engine can overheat and require costly repairs to fix.”

Coolant is a mixture of antifreeze and water. The ratio you mix depends on the temperature where you live. Most popular brands of coolant are premixed 50/50 with water; however, if you live in a very cold area, you may want a mixture that’s more like 70 percent antifreeze and 30 percent water.

In addition to preventing overheating and freezing, antifreeze also protects against corrosion. It slows down the aging process of all parts of your engine’s cooling system by inhibiting rust and scale buildup on internal surfaces. It also helps protect against rusting due to moisture in the air or from condensation that can form inside an unoccupied engine block overnight.

komatsu 40 excavator-Komatsu recommends using 2.61 liters of its proprietary KES 07.895.1-10 (commonly referred to as “Komatsu coolant”) 90% mixed with water and 0.39 liters of 100% Komatsu coolant 10% mixed with water to achieve a freeze temperature of -37 degrees Celsius and a boiling temperature of 129 degrees Celsius.

The Komatsu D51EX, D51PX and D61EX crawler dozers use a unique coolant formula, according to the company’s maintenance manual. This formula is designed to achieve maximum performance of the engine and cooling system, while also protecting against corrosion. Coolant should be added to these machines when they are at normal operating temperature.

komatsu 40 excavator-The Komatsu coolant is prepared and sold in plastic containers of either 1 or 5 liters in volume.

Komatsu coolant is a high quality, ready to use, ethylene glycol based coolant/anti-freeze with a low silicate enhanced formula. It is specifically designed for use in Komatsu heavy-duty diesel engine cooling systems.

The Komatsu coolant is prepared and sold in plastic containers of either 1 or 5 liters in volume.

The Komatsu coolant is tested and approved by Komatsu R&D Department to ensure its performance and compatibility with other Komatsu components. The coolant meets the ASTM D3306 and SAE J1034 specifications for corrosion inhibition and protection against freezing and overheating. The Komatsu coolant is suitable for use with all types of aluminium alloys commonly used in construction machine cooling systems.

komatsu 40 excavator-Currently, the Komatsu 40 utilizes a green coolant.

This coolant can be used in the Komatsu 30 and 30A but you must use it with Komatsu’s coolant additive when used in these units. If you don’t use the hardener, the coolant will break down much faster. There are several benefits to using this type of coolant over ethylene glycol based coolants. Kerosene based coolants don’t contribute to electrolysis and won’t mix with water, which is one of the biggest causes for breakdown in other types of coolants. Furthermore, kerosene based antifreeze/coolants don’t contribute to foaming as readily as ethylene glycol based products. The operating temperature range for this type of coolant is between -40 and +40 degrees Fahrenheit (without the additive) or between -60 and +40 degrees Fahrenheit (with the additive).

komatsu 40 excavator-Komatsu 40 excavator uses the same coolant as the Komatsu PC-400 excavator.

Komatsu has a special coolant that is required in their excavators. This coolant is also used in the PC-400 excavator.

The coolant is not very expensive and usually costs less than $10 per gallon. It is sold at most auto parts stores and can be purchased online as well.

Most of the time, you will need to use the same brand of coolant that was put in when the machine was manufactured.

However, if your excavator uses a different type of coolant, then it may be possible to buy it from another manufacturer that makes this type of fluid for other types of equipment.

komatsu 40 excavator-Komatsu Radiator Coolant is KES 07.851.1

Komatsu Radiator Coolant is KES 07.851.1, which is a heavy-duty diesel engine coolant with a service life of up to 750,000 km / 12,000 hours.

Komatsu Radiator Coolant is suitable for use in all makes and models of heavy-duty engines, including Komatsu, Caterpillar, Detroit Diesel, Deutz and Isuzu engines. It can also be used in many other applications including generators and earthmoving equipment.

Komatsu Radiator Coolant has exceptional wetting properties which ensure excellent heat transfer to the radiator core.

Komatsu Radiator Coolant is formulated with an organic corrosion inhibitor package that provides superior protection against corrosion of all metals used in modern cooling systems such as aluminium, iron and copper.

It also contains a patented cavitation inhibitor which protects water pump seals from damage due to cavitation (the formation of vapour bubbles when the water pump impeller rotates).

komatsu 40 excavator-You should use the recommended radiator coolant for your Komatsu 40 excavators.

Operators should always use the suggested radiator coolant for their Komatsu 40 excavators. The Komatsu 40 excavator is a diesel powered piece of heavy machinery used in construction and demolition. It has six cylinders, which are cooled by a radiator system that circulates coolant between the engine block and the radiator.

The correct coolant to use in the Komatsu 40 excavator is EC-1. This is a special type of coolant designed to protect aluminum components from corrosion and cavitation. It is also an extended life coolant, meaning it doesn’t require as frequent change-outs as traditional coolants.

Checking Engine Coolant Level

The owner’s manual for your Komatsu 40 excavator will have specific instructions for checking your engine’s coolant level. In general, you’ll need to check the level with the engine off and cold. A dipstick or stick gauge will show you how much fluid to add if necessary.
