Toyota Red vs Pink Coolant – Which is Better?

So, it is time to change the coolant in your Toyota, but you are wondering what is better, Toyota Red Long Life Coolant or Toyota Pink Super Long Life Coolant. These are two main coolants available from Toyota and while they look similar, there are some differences.

Is Toyota Pink Coolant Just Premixed Red?

No, Toyota Pink Coolant is not just premixed Red. The pink coolant is an OAT (organic acid technology) that typically has a longer service life. The red coolant on the other hand is an IAT (inorganic acid technology) that is considered to be more “conventional” but still longer lasting than some other coolants on the market.

What Are the Ingredients of Each Coolant?

Toyota Pink Super Long Life Coolant:

  • Water (7732-18-5)
  • Ethylene Glycol (107-21-1)
  • Diethylene Glycol (111-46-6)
  • Sebacic Acid (111-20-6)
  • Potassium Hydroxide (1310-58-3)

Toyota Red Long Life Coolant:

  • 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)

Which Toyota Coolant is the Longest Lasting?

Toyota claims that their Pink Coolant is good for up to 160,000 km (100,000 miles) or 10 years for the factory fill and then needs to be changed every 100,000 km (60,000 miles) or 5 years after that. The red coolant has a much shorter life and needs to be changed every 50,000 km (30,000 miles) or every 2 years.

Which Toyota Coolant is the Cheapest?

While Toyota Pink Coolant does last a lot longer than Red it is quite a bit more expensive. This is in part because it is only available as 50/50 pre-mixed formula whereas Toyota Red is not pre-diluted.

Which Toyota Coolant is Better for Older Cars?

It is generally recommended that you use Toyota Red in older vehicles. This is mainly due to the fact that older Toyotas usually have non-aluminium radiators and Pink is not formulated with the inhibitors necessary to protect them. The Red Long Life coolant had molybate and a triazole to protect the metals (copper, etc.) in the older radiators.

Toyota Red can also be used in later model cars, but from the factory they come with Pink. The Pink coolant was used in most Toyotas from the early to mid 2000s

So, Which Coolant is the Best?

This really comes down to the model and year of your car. If you have a modern Toyota with an aluminium radiator, Pink is probably the coolant you want to go for. However, if you do not mind changing the coolant frequently, Toyota Red can be used on newer cars if you want to save a few bucks (remember it needs to be mixed with water).

For older cars it is recommended that you use Toyota Red and not Pink as per the advice above.

Can I Mix Toyota Red & Pink?

Toyota does state that their two coolants are compatible, but we would always exercise caution when mixing coolants. If you are thinking about changing between them we would flush the system completely before adding the new, different coolant.
