Mobil Delvac Modern™️ Coolant Hydro Protection Ready Mixed

Mobil commercial-vehicle-lube , Australia

Ready to use Pre-diluted Coolant

Product Description

Mobil Delvac Modern™️ Coolant Hydro Protection Ready Mixed is a water-based ready to use pre-diluted coolant based on Organic corrosion inhibitor Additive Technology (OAT) chemistry. It is suitable for use in stationary engines in power generation, marine and automotive applications where glycol-based antifreeze is not required.


Features and Benefits

Recommended maximum service life:

 Heavy duty diesel on-road 650,000 km 
 Heavy duty diesel off-road 8,000 hours
 Stationary power generation and marine 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

Complete cooling system protection

The OAT inhibitor provides corrosion protection for aluminium, iron, steel, copper solder alloys and a wide range of other engine and cooling system metals. The corrosion inhibitor is effective at preventing wet liner cavitation erosion.

Long service life

The very low depletion rate of the OAT inhibitor ensures long-term corrosion protection under all operating conditions.

Reduced maintenance

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