Fuel burns constantly in your car’s engine. Much of the heat from this combustion goes right out the exhaust system, but some of it goes into the engine heating it up. The primary job of the cooling system and coolant is to prevent the engine from overheating by transferring this heat to the air. TecLub offers a complete range of private label coolants that keep your engine cool and the entire cooling system clean, lubricated and protected against rust and corrosion.
Coolant or antifreeze?
The terms coolant and antifreeze are often mixed up. Luckily the difference is fairly simple: a coolant is a ready mixed product, ready to be used in a cooling system. An antifreeze is the concentrated product which needs to be mixed with demineralized water before use.
Function of coolants
The main functions of coolants are the following:
- Heat transfer (preventing engine overheating)
- Boiling protection
- Freezing protection
- Corrosion, cavitation and erosion protection
For coolants, we can distinguish between international specifications and OEM specifications. Some examples of well-known specifications are:
- International specifications: AFNOR NF R15-601, BS 6580: 2010, AS 2108, ASTM D3306, ASTM D4656, ASTM D4985
- OEM specifications: VAG Group (Volkswagen, Audi, Skoda, SEAT): VAG TL-774 C (G11), VAG TL 774 D & F (G12 / G12+), VAG TL 774 G (G12++), VAG TL 774 J (G13)
- MB 325.5 / 325.6, Ford ESD-M97B49-A, GM GME L1301, BMW / Mini GS 94000
Compatibility / miscibility
What about the compatibility and miscibility of the different grades? Are they all compatible with each other? The answer is NO. In the below table you can see which grades are compatible:
It is always recommended to follow the OEM’s recommendation for the right type of coolant. Optimal performance and longevity of service is guaranteed by exclusive use of one type of coolant.
