The next time you look inside a TDI motor that has run G-12 for 300,000 miles you won't find the slighest bit of corrosion! G-12 far and away has some of the best qualities of any coolant I have ever seen. Keep in mind that the G-12 is significant enough that if mixed with coolants like Dex-Cool or conventional coolants that your motor will suffer severe damage. The coolant does not have to be mixed exactly 50/50 you can get away with running 60/40 with no issues.Click to expand.I am pretty sure that only Mercedes and VW coolants are compatible and both are "Phosphate Free" HOAT based coolants. If the problem comes back then deal with that. If it was just a little low on coolant you could have just add some distilled water and call it good-to-go for now. Much as I was looking forward to saving money by buying the red ($31.84/gal which would make 2 gals when diluted), I caved and spent $21.81 to get a gal of the pink as it is spec'd for my car. OTOH, the two chemical differences between red and pink as stated on the jugs might just be marketing mumbo jumbo BS to get people who bought cheaper cars to spend more money on parts. But, the pink "Super Long Life" product might be formulated to be nicer to engines it's spec'd for over a longer period of time than the red. Will using red in your Yaris, or mixing the two, cause engine damage? Doesn't sound like it, at least not in the short term. So, while the pink and red are similar and compatible it would appear that they are not quite exactly the same thing. He even walked out to the shop to ask a tech whether he knew if the pink and red were exactly the same thing, but he said he didn't know. The second component had a completely different name and number on each jug. Interestingly, one of the components had the same number on both products, but the name was different. They were the same in both, except for two components, I believe an acid and some chemical. He went and got a gallon of each and showed me in the Contents list how there is a little difference in the composition between the two and they are spec'd for different model year ranges of vehicles.Įach component in the product has a name and number (even the water in the pink). I told him I thought the pink was just diluted red. He said he thought the pink was spec'd for it and checked his book and confirmed. He asked about my car and I told him it was an '07 Yaris. As my coolant is down a little I went over to the local dealer this afternoon to buy a gallon of red. Our toyota technical rep said its basically the same antifreeze without dilution. its cheaper, and essentially the same as toyota pink. You might say why thermostat housing.well when I didn't get the amount after draining all else and that I wanted to replace the thermostat anyway, when i popped the housing off there is a cavity area behind it and the waterpump that held the rest that won't drain.īuy toyota red and dilute it. I did do a complete drain (block, radiator lines, fluid overflow tank & thermostat housing) taking out the amount for AT shown above. Long−life hybrid organic acid technology. Only use “Toyota Super Long Life Coolant” Without getting into it.you didn't define empty but as quoted from another post vįill.
