A. An OEM Specification is the coolant requirement set by a vehicle or equipment manufacturer (e.g., MB 325.3, VW TL 774-D / G12+). When a coolant lists the code, the coolant manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a coolant engineered for your machine.
A. An OEM Approval means the coolant has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 325.3). An Approval confirms the coolant is recognised by the equipment manufacturer for service use in their machines.
