Mobil Delvac Modern™ Coolant Hydro Protection Concentrate
Mobil commercial-vehicle-lube , Australia
Product Description
Mobil Delvac Modern™ Coolant Hydro Protection Concentrate is a water-based corrosion inhibitor concentrate 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.
ExxonMobil recommends that the concentrate be used at 7.5% treat rate in water (7.5% Concentrate 92.5% Water) The concentrate can be used up to concentrations of 10% treat rate (10% Concentrate 90% Water) where extreme corrosion protection is required, but it is not recommended that this treat rate be exceeded.
Features and Benefits
Recommended maximum service life based on 7.5% treat rate in water (7.5% Concentrate 92.5% Water):
| 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. |
Applications
• Automotive Engine cooling systems
• Engines in construction, earthmoving, mining and quarrying equipment cooling systems
