Finol CoolTemp U OAT Red RTU – Premixed Long-Life Engine Coolant & Antifreeze

Finol CoolTemp U OAT Red RTU is a ready-to-use long-life engine coolant and antifreeze formulated with high-purity monoethylene glycol and Organic Acid Technology (OAT) corrosion inhibitors.

Supplied pre-mixed and ready for immediate use, it removes the need to dilute coolant concentrate with water before filling. The formulation is designed to provide year-round protection against freezing, overheating, corrosion, cavitation and deposit formation in compatible engine cooling systems.

The OAT formulation is free from nitrites, amines, phosphates, borates and silicates, making it suitable for a wide range of modern petrol and diesel engines, commercial vehicles, agricultural machinery, construction equipment and other compatible applications.

Long-Life OAT Cooling Protection

The Organic Acid Technology used in this coolant is designed to provide long-term corrosion protection while helping maintain the condition of the engine cooling system.

The coolant helps protect components such as radiators, water pumps, engine blocks, cylinder heads and other cooling system parts from corrosion and cavitation. Maintaining the correct coolant in the system also helps support effective heat transfer and engine temperature control.

Ready-Mixed – No Water Required

Unlike concentrated antifreeze, Finol CoolTemp U OAT Red RTU is supplied at its intended ready-to-use concentration.

This makes it particularly convenient for:

• Routine coolant top-ups
• Complete coolant changes
• Workshop servicing
• Fleet maintenance
• Agricultural machinery servicing
• Commercial vehicle maintenance
• Plant and construction equipment

There is no need to calculate an antifreeze-to-water ratio before use. Always follow the equipment manufacturer's instructions for coolant replacement and top-up procedures.

Product Information

Important Compatibility Information

Coolant colour should not be used on its own to determine compatibility. Red, pink or similarly coloured coolants can use different inhibitor technologies and should not automatically be mixed.

Before using Finol CoolTemp U OAT Red RTU, check the vehicle, engine or machinery manufacturer's recommended coolant specification. If changing coolant technology, follow the manufacturer's recommendations for draining and flushing the existing coolant.

Finol CoolTemp U OAT Red RTU for Workshops & Fleets

For garages, agricultural businesses, plant operators and commercial fleets, a ready-to-use coolant can make routine maintenance simpler. Finol CoolTemp U OAT Red RTU can be used directly from the container where the required OAT specification is suitable for the application.

Its availability in 1 litre, 5 litre, 20 litre, 200 litre and bulk quantities also makes it suitable for everything from individual vehicle servicing to higher-volume workshop and fleet requirements.
