Coolant/Anti Freeze D4D

Hi All
Can anyone tell me what type of coolant is the the 3.0L D4D engine as standard (ie from the factory and what Toyota service centres use)? I am heading up to the snow in July and want to know if I need to change the coolant or will it be ok.
Cheers in advance.

Toyota Super Long Life. Costs about the same from the dealer as Supercheap sell aftermarket coolant for.

Cheers for that. According to the Nulon website, the equivalent coolant to match the Toyota Super Long Life is good for -37degC.

Just don't buy the wrong coolant from Toyota. If it says "concentrate" on the genuine Toyota coolant bottle, it's the old coolant. Toyota Super Long Life Coolant (SLLC) is pink, and is sold as a premix only by Toyota dealers in Australia.

The two products are very different. Red is for very old Toyotas. Pink is for newer Toyotas.

Toyota Red Long Life ingredients: Ethylene Glycol(107-21-1),Diethylene Glycol(111-46-6) Water(7732-18-5) Orangic Acid Salt(532-32-1) Hydrated Inorganic Salt(1310-58-3)

Toyota Super Long Life Antifreeze/coolant ( Pink ) ingredients: Water (7732-18-5), Ethylene Glycol (107-21-1), Diethylene Glycol (111-46-6), Sebacic Acid (111-20-6), Potassium Hydroxide (1310-58-3)

Super Long Life is a HOAT coolant (typically what most green coolants are). The old toyota coolant is OAT coolant.

HOAT a good liquid? I've heard a lot of reviews about it, which were quite negative.
I had the same problem and so I carefully searched for information about it. My brother works as a car mechanic and he told me how I can fix it. He said read it https://thetoolscout.com/fridge-not-cooling/ and to see and try if I can fix it, he couldn't help me at that time, because he was in another city and so I had to do it myself, but I still fixed this problem.
The funny thing is that at first I thought of a completely different solution and tried to fix it, but it didn't work out. I have never used HOAT and I want to get more information about it, as the reviews about it are very, very different
