Mobil Delvac Modern™ Coolant Extended Life Ready Mixed

Mobil commercial-vehicle-lube , Australia

Ready to use Pre-diluted Coolant/Antifreeze

Product Description

Mobil Delvac Modern™ Coolant Extended Life Ready Mixed is a 50/50 ready to use pre-diluted non-nitrited Coolant/Antifreeze for heavy duty and light duty vehicles and equipment.

Mobil Delvac Modern Coolant Extended Life Ready Mixed offers freeze protection down to -36 deg C and increase boiling point of 8 deg C.


Features and Benefits

Mobil Delvac Modern Coolant Extended Life Ready Mixed is a heavy-duty, ethylene glycol engine coolants based on Organic corrosion inhibitor Additive Technology (OAT). It is free of amines, borates, nitrates, nitrites, phosphates and silicates. The product provides excellent protection of the metal alloys found in most cooling systems. Being phosphate and silicate free also eliminates the risk of hard water scale.

Note: Do not use in potable water systems.


Recommended maximum service life:

Passenger Car and Light Commercial Vehicle 250,000 km 
Heavy Duty Diesel On-Road 650,000 km 
Heavy Duty Diesel Off-Road  6,000 hours 
Stationary Engines  32,000 hours 


It is recommended to change the coolant every five years or when above mileages/operating times are reached, whichever comes first.



Advantages and Potential Benefits

Cost Effective

Supplementary Coolant Additives (SCAs) are not required to achieve to achieve maximum service lives listed.


Effective protection against corrosion erosion and pitting even on sensitive metals like aluminium.

Reduced maintenance

With proper top-up practices regular use of testing and supplemental coolant additives is avoided.

Heat Transfer

Silicate free formulations eliminates deposits which may impede heat transfer.

Hardware Life

Enhanced water pump life through reduce risk of seal wear.

Broad operating temperature range

Protection against winter freeze-up and summer boil-over.

Wide Range of Applications

Protects engines where the OEM specifies a nitrite and molybdate free coolant. Can be used in heavy duty engines using EGR, DPF or ACERT technologies. Suitable for mixed fleet applications.


While compatible with conventional antifreezes dilution with conventional antifreeze could reduce extended life benefits. ExxonMobil recommend that the diluted coolant made from this concentrate is not diluted by more than 25% with other coolant formulations to maintain performance claims.


Can be stored for approximately 8 years in sealed containers without any effect on the product quality or performance.



• Heavy duty engines where the OEM recommends a nitrite free, silicate free coolant.

• Suitable for mixed fleets of passenger vehicles, light and heavy-duty trucks, or off-road on-road and marine cooling systems where the OEM requires a Nitrite and Silicate free coolant.
