This article attempts to answer most of these and some other questions by breaking things down into bite-size chunks that are easy to understand.
#Auto coolant color series#
With this complexity comes a series of questions ranging from “what’s the difference between a red coolant and a green coolant?” or “what will happen if I mix the two?” to “is ethylene glycol the same as propylene glycol?” Coolants serve relatively simple but important purposes in automotive and industrial applications - corrosion prevention, freeze and boil protection if required.īut in a market of ever-increasing technologies, OEM requirements, and even colors, coolants can seem very complex, maybe even downright vexing. If you are thinking about changing between them we would flush the system completely before adding the new, different coolant.A coolant or an antifreeze as it is commonly referred to, is a liquid that helps regulate the vehicle engine temperatures during operation. Toyota does state that their two coolants are compatible, but we would always exercise caution when mixing coolants. 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).įor older cars it is recommended that you use Toyota Red and not Pink as per the advice above. If you have a modern Toyota with an aluminium radiator, Pink is probably the coolant you want to go for. This really comes down to the model and year of your car. The Pink coolant was used in most Toyotas from the early to mid 2000s So, Which Coolant is the Best? Toyota Red can also be used in later model cars, but from the factory they come with Pink. The Red Long Life coolant had molybate and a triazole to protect the metals (copper, etc.) in the older radiators. 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.
It is generally recommended that you use Toyota Red in older vehicles. Which Toyota Coolant is Better for Older Cars? You can get a great deal on genuine Toyota Red coolant here on Amazon This is in part because it is only available as 50/50 pre-mixed formula whereas Toyota Red is not pre-diluted. While Toyota Pink Coolant does last a lot longer than Red it is quite a bit more expensive. The red coolant has a much shorter life and needs to be changed every 50,000 km (30,000 miles) or every 2 years.
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. Which Toyota Coolant is the Longest Lasting? What Are the Ingredients of Each Coolant? 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. The pink coolant is an OAT (organic acid technology) that typically has a longer service life. No, Toyota Pink Coolant is not just premixed Red. Is Toyota Pink Coolant Just Premixed Red? These are two main coolants available from Toyota and while they look similar, there are some differences. 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.
