There's more to coolants than just cooling. It is important to use the correct type of coolant specified for your vehicle, for reasons of material and additive compatibility, which affects corrosion resistance, deposit formation and, ultimately, component longevity (particularly aluminium and rubber swelling). Lobrid coolants use a combination of organic additives with a small amount of inorganic additives.Īll four coolant types work well when used in their intended applications and when used as specified. Hybrid coolants use a combination of organic and inorganic additives. Newer coolants that use organic additives (organic acid technology or OAT) have significantly reduced depletion rates and require much less frequent replacement intervals. Traditional coolants that use inorganic additives, such as silicates and phosphates, tend to deplete much faster and require more frequent replacement intervals. Mono-ethylene glycol hybrid coolant (OAT with reduced phosphates, but no silicates, nitrates, amines or borates) dyed pink. If we're talking in the context of older vehicles, then you could probably get away with that - but for modern vehicles, that just doesn't cut it. I know many people who have flushed their systems and have gone over to green for the simple fact that the long term running costs are far less.Whoever told you all that is not strictly correct. To be honest, there really is no difference between red and green coolant apart from the cost. I find the toyota (red) coolant is very good and ran this for a while. As such, Volkswagen recommends that:Ī car factory-filled (or flushed and refilled) with G12 should be topped up with G12 or G12+ or G12++ or G13.Ī car factory-filled (or flushed and refilled) with G12+ should be topped up with G12+ or G12++ or G13.Ī car factory-filled (or flushed and refilled) with G12++ should be topped up with G12++ or G13.Ī car factory-filled (or flushed and refilled) with G13 should be topped up with G12++ or G13.Īlways refer to the owner's manual on which coolant/s the vehicle should use.Įven though one would always reco factory, to my knowledge, any pink / red coolant can be substituted. However, in terms of vehicle application, G12, G12+, G12++ and G13 coolants should generally be used in a forward-compatible (rather than backward-compatible) manner. In terms of chemical compatibility, all G12 and G13 coolants can be mixed with each other. Mono-ethylene glycol and glycerine lobrid coolant (OAT with reduced silicates, but no nitrates, amines or phosphates) dyed purple. Mono-ethylene glycol lobrid coolant (OAT with reduced silicates, but no nitrates, amines or phosphates) dyed purple. Mono-ethylene glycol OAT coolant (no silicates, nitrates, amines, borates or phosphates) dyed purple. Mono-ethylene glycol OAT coolant (no silicates, nitrates, amines, borates or phosphates) dyed red. Mono-ethylene glycol hybrid coolant (OAT with silicates but no nitrates, amines or phosphates) dyed blue. These days, it would extremely unwise to go by colour alone when deciding which coolant to use, as demonstrated below: If it doesnt have that I wouldnt use it in my vehicles To get this approval they have to submit a product for testing (at a cost) and if it passes they get a letter like this which allows them to put "Approved by VW on the product container Lots of products state they are "compatible " with VW but it the ones that have "Approval" that should be used. it seems they both have their pros can cons. Most important thing is you do youe research before deciding to go either red or green,īy no means am I trying to state that red is better or vice versa. I guess like everthing, people have choices and ultimately the choice comes down ot the the end user. Myabe the newer stuff has come along way in recent years. and many of them claim that they are compatible with VW Motors,etc. Funnily enough, needed to go and pick up some oil and whilst in the shop, had a quick look at some of the green coolants at hand out of curiosity (sorry guys, im one of those real inquisative people) to take a look at specs, etc.
