Morris Ultralife Red is a high-performance Organic Acid Technology (OAT) antifreeze designed for automotive and commercial professionals who demand long-term corrosion protection and engine longevity. Ideal for modern cooling systems in passenger cars, vans, and heavy-duty machinery, this concentrated ethylene glycol formula effectively prevents frost damage down to -40oC when diluted to a 50% concentration. While it offers a convenient 5-year service life, users must ensure their vehicle's cooling system specifically requires an OAT-based formula to prevent incompatibility with older non-OAT cooling system components.

No. Mixing Morris Ultralife Red (OAT) with different types of coolant, such as IAT or HOAT, can cause chemical reactions that result in sludge, leading to engine damage.
Tap water contains minerals and chlorine that can interfere with the OAT chemistry, potentially leading to scale buildup and a reduction in the coolant's service life.
It is generally not recommended for older vehicles that were designed for traditional inorganic coolants, as the OAT chemistry may not be compatible with older seals or radiator materials.
While it has a 5-year life, it is good practice to check the coolant level and condition during your regular vehicle service intervals.
OAT coolants are much more stable and do not deplete their protective additives as quickly as traditional coolants, resulting in longer service intervals and better corrosion protection.
This often indicates leftover residue from a previous, incompatible coolant. Flush the system thoroughly with clean water before refilling.
Check the cooling system for air locks or potential blockages in the radiator. Ensure the system was properly bled during the refill process.
Before adding Ultralife Red, ensure the cooling system is completely drained and flushed of old, incompatible fluids to prevent chemical reactions. This coolant is compatible with major specifications including VW G12+, Mercedes MB 325.3, and Ford WSS-M97B44-D. Always check your vehicle owner's manual to confirm an OAT-based, G12-rated coolant is specified for your engine model. When handling, wear protective gloves and eyewear, as ethylene glycol is hazardous. Store the container in a cool, dry place and ensure the cap is tightened firmly to prevent moisture contamination.
