The New Holland 73344307 Extended-Life OAT Coolant/Antifreeze is a 1-gallon, 50/50 premix coolant that meets MAT 3724 specifications and provides long service life protection for FPT Tier 4 and Tier 4 Final engines. This ready-to-use formula requires no dilution and protects the cooling system down to -34°F, guarding against freeze damage in cold climates and boil-over during peak summer use.

NOTE: Conventional coolants and OAT coolants must never be mixed in the same system, as mixing degrades the additive package and can lead to gel formation, deposit buildup, liner cavitation, and corrosion that damages expensive engine components.
